Dynamics of Two Dimensional Projectile Motion

Dynamics of Two Dimensional Projectile Motion Experiment: Study of Projectile Motion SUMMARY Moving an object in a bilaterally symmetrical, parabolic path is called Projectile motion. The path followed by the object is called its trajectory (Boundless, 2014). Some of examples are as follows:- Firstly, projectile is dropping object from rest position; secondly, an object thrown vertically upward is also called projectile in the end, an object which is thrown at an angle upward to the horizontal is also a projectile (providing effect of air resistance is negligible). Furthermore, in projectile object that once projected or dropped remains in motion by its own inertia and is inclined only by the downward force of gravity (Anonymous, 1996). KEY POINTS OF PROJECTILE MOTION: Time of Flight, T: The time of flight depends upon two things that are angle of projection and initial velocity of an object. Moreover, the vertical displacement of an object will be zero when the point of projection and return will be on the same horizontal surface (Boundless, 2014). Symmetry: If the point of projection and return occur along the same horizontal surface means current motion is symmetrical in the vertical plane (Boundless, 2014). Maximum Height, H: When the vertical component of velocity, vy, will be equals to zero shows the maximum height of an object. Projectile goes against gravity as it moves up, so the velocity decelerates likewise velocity accelerates downward under gravity (Boundless, 2014). Range of the Projectile, R: Displacement in the horizontal direction is called range. Acceleration is absent in this direction and the line of range shown when gravity only acts vertically (Boundless, 2014). As shown in this image, range of projectile is independent of the forces of gravity (Boundless, 2014). OBJECTIVES The purpose of this experiment was to analyze the dynamics of two dimensional projectile motion. Moreover, this was done by providing a ball with a horizontal velocity and measuring the time of flight and range. Furthermore, check the systematic errors in the data by comparing the values of vertical and horizontal acceleration. PRIMARY OBJECTIVE: To follow the two dimensional motion of an object and to determine that the motion can be analyzed by considering the motion in each dimension separately. SECONDARY OBJECTIVE: To check the existing possible systematic errors by comparing the horizontal acceleration with expected value of zero and vertical acceleration with the accepted value for g. THEORY Figure above is showing the experimental setup displaying measured values of initial height, range and time of flight The ball According to the Newton’s first law of motion, there will be no acceleration in horizontal direction, unless a horizontally directed force acts on the ball. Ignoring the air friction, only force acting on the ball during flights is the force of gravity. The range is the horizontal distance, x, between the hooter of the launcher and the place where the ball lands. The range is given by x = (v0 cos à ¸) t, Where v0 is the initial speed of the ball as it leaves the hooter, à ¸ is the angle of inclination above the horizontal, and t is the time of flight. If the ball is shot horizontally (à ¸ = 0), then the cos à ¸ = 1 and the range is given by x = v0 t. The time of flight will be t = x / v0 [Equation 1] The vertical distance, y, that the ball falls in time t is given by y = v0y t + 1/2 g t2 where v0y = 0 thus giving y = 1/2 g t2. Substituting for time, t with equation [1] will yield EXPERIMENTAL METHOD Equipment required: 1: Science Workshop Interface 2: A photo gate motion sensor 3: Time-of-flight timing sensor pad 4: Projectile Launcher 5: A plastic ball 6: Measuring tape Experimental procedure: Firstly, set up the angle that you have to launch by using the protractor; angles are 0, 30 or 60. Secondly, with the help of ramrod set the ball into the launcher. Moreover, the most important point is setting the right range that you wanted to calculate that is short, medium or long range. After that adjust the time of flight sensor pad, open the software â€Å"Projectile Motion† on computer and activate the application. By pulling the trigger launch the ball; note the reading for the time of flight from computer and then by using ruler measure the range. Take measurements three times for each range (short, medium, long range). Furthermore repeat the same process and take measurements three times for each angle (short range at 30 and 60). QUESTION/ANSWERS How do the values for the time of flight for short, medium and long range distances compare when the ball was launched horizontally? Also compare the values with the theoretical value of time of flight at 0. How do the values for the time of flight in horizontal, 30 and 60 launch compare when the ball was launched (in short range)? DISCUSSION Object moving in both motions that is falling free under gravity and moving both in horizontal direction is called as projectile motion; both the vertical and horizontal motions occur simultaneously but they don’t depend on each other. Moreover, after inputting the diameter of the ball into Data Studio we began our first shot at angle 0 and then according to that adjusted the landing pad to start collecting data. Furthermore, during this process we were making sure that the launcher speed remains same in every shot and also its angle; there were no problems in recording the data. CONCLUSION Projectile motion is two dimensional motion under constant acceleration due to gravity. Moreover, it is not necessary that an object should be thrown with some initial velocity in the horizontal direction; it is clear that there is a relationship between the angle of takeoff and the distance from which ball is thrown. Furthermore, the motion of a projectile can be studied easily by resolving it into horizontal and vertical components which are independent of each other. STUDENT’S SUGGESTION We have learned many things from this experiment like to calculate total time of the flight of an object and the prediction of landing point of a projectile. Moreover, Projectile motion helps in hitting the target. In addition, some of the real life examples are as follows: A golfer needs to know at what angle above the ground the golf ball should travel to reach closer to the golf pot, there are many applications of a projectile. Real life applications of projectile include bullets on a straight spinning flight, rockets, and missiles. Furthermore, football kicked off by a player, a ball thrown by a cricketer and a missile fired from launching pad, all projected at some angles with the horizontal, are called projectiles.

The Gallant Boys of Gettysburg :: essays research papers

The story I read took place mostly at the Battle of Gettysburg. Tom and Jeff Majors had just enrolled in the Confederate army. Tom enrolled as a private and Jeff as a drummer boy. Their dad, Nelson Majors, who had been in the army for quite some time, had just been promoted to Major. Tom and Jeff were appointed to their father's unit. They fought in the Battle of Gettysburg which was the worst battle of the Civil War. The death total for the battle was great. The Union and the Confederates lost a total of 18,000 men each. During the worst part of the battle, a shell hit Tom's leg. Jeff immediately carried him to the field doctor. The doctor told Tom that his leg would have to be cut off. The Confederate army was being beaten back by the Union and they had to retreat. That meant that Tom was put on a wagon and carried away. Tom knew there was little chance of him surviving the ride. Jeff had an idea to take Tom to the Poteets' house. They had eaten with them before the battle. The Poteets gladly agreed to keep Tom for a short while at their house. Jeff and Nelson Majors were very happy that Tom could stay with them. When Tom's leg was healed, he and Jeff went back to Kentucky where their family was from. When they got home there was a big welcome dinner. A letter came a few days later telling Jeff that he would need to go back to the army. When Jeff got back, he and his dad talked about how Tom was doing and the rest of the family. After that, the story ends just as they were about to go fight another battle. The predominate conflict in The Gallant Boys of Gettysburg occurred when Tom was hit by a shell from the Union army. Jeff turned and saw Tom rolling and rolling on the ground. When Jeff got there, he saw that it had struck Tom's leg. He quickly tied a bandage on it to stop the bleeding. Jeff told Tom that he would have to instantly see a field doctor. The doctor told Tom that his leg would have to be taken off. When Jeff and Tom arrived at their home in Kentucky, Sarah, Tom's girlfriend, saw what had happened to his leg.

The Safety and Benefits of Creatine :: essays research papers fc

The Safety and Benefits of Creatine Topic:  Ã‚  Ã‚  Ã‚  Ã‚  The Safety and Benefits of Creatine General Purpose:  Ã‚  Ã‚  Ã‚  Ã‚  To inform Specific Purpose:  Ã‚  Ã‚  Ã‚  Ã‚  To inform my audience of the safety of creatine use and also to inform them of the benefits creatine use can provide. Central Idea:  Ã‚  Ã‚  Ã‚  Ã‚  Many people are misinformed on the subject of creatine use and exactly what it is and what creatine can do. Organizational Pattern:  Ã‚  Ã‚  Ã‚  Ã‚  Topical Introduction I.  Ã‚  Ã‚  Ã‚  Ã‚  How would you like to be able to increase your strength or even increase your bench press by 25 pounds in less then ten days? Or how about improving your endurance. What if I were to say this can be accomplished without taking any harmful or illegal substances. These types of results have been recorded with the use of the supplement creatine. II.  Ã‚  Ã‚  Ã‚  Ã‚  I first became interested in weight training when I was in high school. After poor gains from weight training alone I stumbled upon the keys to success, proper nutrition and supplementation. Creatine is a supplement I have used for awhile and strongly believe it has accelerated my strength and size gains. In three and a half years amount of time I have gained 62 pounds from 153 at the beginning of my senior year in high school to currently 215 pounds. III.  Ã‚  Ã‚  Ã‚  Ã‚  Today, I will explain how creatine use can be beneficial and also safe to use with no harmful side effects. Also, I hope to inform you of what and how natural the substance creatine really is. Body I.  Ã‚  Ã‚  Ã‚  Ã‚  How many people here have heard creatine is bad for you, or heard stories of creatine hurting someone who has taken it? A.  Ã‚  Ã‚  Ã‚  Ã‚  Many studies have been performed on creatine to determine if there are any adverse side effects from creatine consumption when taken at an amount of 3-5 grams. II.  Ã‚  Ã‚  Ã‚  Ã‚  Creatine is a natural occurring substance. Ray Sahelian MD has done extensive research on creatine. A.  Ã‚  Ã‚  Ã‚  Ã‚  Sahelian states â€Å"Creatine is not an herb, mineral, vitamin, hormone, or steroid.† 1.  Ã‚  Ã‚  Ã‚  Ã‚  Creatine is a natural nutrient found in our bodies and the bodies of most animals. 2.  Ã‚  Ã‚  Ã‚  Ã‚  Approximately 95% of the body’s creatine supply is found in the skeletal muscles. B.  Ã‚  Ã‚  Ã‚  Ã‚  Creatine is easily absorbed through the intestinal tract and into the bloodstream. 1.  Ã‚  Ã‚  Ã‚  Ã‚  Creatine production occurs in the liver, pancreas and kidneys. C.  Ã‚  Ã‚  Ã‚  Ã‚  From Sahelian study it is easy to see that creatine is a natural substance found in food. By taking creatine as a supplement all you are doing is increasing the amount of natural creatine the body has. III.  Ã‚  Ã‚  Ã‚  Ã‚  Creatine is not only safe but has also been found to be beneficial for overall health.

The Lost Duke of Wyndham Chapter Twenty

Outside the carriage, the atmosphere was considerably less tense. The three men remained on horseback, never quite in a line. Every now and then one of them would increase his pace or fall behind, and one horse would pass another. Perfunctory greetings would be exchanged. Occasionally someone would comment on the weather. Lord Crowland seemed rather interested in the native birds. Thomas didn't say much, but – Jack glanced over at him – good Lord, was he whistling? â€Å"Are you happy?† Jack asked, his voice a bit short. Thomas looked back in surprise. â€Å"Me?† He frowned, thinking about it. â€Å"I suppose I am. It's a rather fine day, don't you think?† â€Å"A fine day,† Jack echoed. â€Å"None of us is trapped in the carriage with that evil old hag,† Crowland announced. â€Å"We should all be happy.† Then he added, â€Å"Pardon,† since the evil old hag was, after all, grandmother to both of his companions. â€Å"Pardons unnecessary on my account,† Thomas said. â€Å"I agree with your assessment completely.† There had to be something significant in this, Jack thought – that their conversation kept returning to how relieved they all were not to be in the dowager's presence. It was damned strange, to tell the truth, and yet, it did make one think†¦ â€Å"Will I have to live with her?† he blurted out. Thomas looked over and grinned. â€Å"The Outer Hebrides, my man, the Outer Hebrides.† â€Å"Why didn't you do it?† Jack demanded. â€Å"Oh, believe me, I will, on the off chance I still possess any power over her tomorrow. And if I don't†¦Ã¢â‚¬  Thomas shrugged. â€Å"I'll need some sort of employment, won't I? I always wished to travel. Perhaps I shall be your scout. I'll find the oldest, coldest place on the island. I shall have a rollicking good time.† â€Å"For God's sake,† Jack swore. â€Å"Stop talking like that.† He did not want this to be preordained. He did not want it to be understood. Thomas ought to be fighting for his place in the world, not blithely handing it over. Because he himself did not want it. He wanted Grace, and he wanted his freedom, and more than anything, right at that very moment, he wanted to be somewhere else. Anywhere else. Thomas gave him a curious look but said nothing more. And neither did Jack. Not when they reached Pollamore, or Cavan town, or even as they rode into Butlersbridge. Night had long since fallen, but Jack knew every storefront, every last signpost and tree. There was the Derragarra Inn, where he'd got himself drunk on his seventeenth birthday. There was the butcher, and the blacksmith, and ah, yes, there was the oatmeal mill, behind which he'd stolen his first kiss. Which meant that in five – no, make that four – more minutes, he would be home. Home. It was a word he had not uttered in years. It had had no meaning. He'd lived in inns and public houses and sometimes under the stars. He'd had his ragtag group of friends, but they drifted in and out of togetherness. They thieved together more by convenience than anything else. All they'd had in common was a shared past in the military, and a willingness to give a portion of their bounty to those who had returned from the war less fortunate than they. Over the years, Jack had given money to men without legs, women without husbands, children without parents. No one ever questioned where he'd got the money. He supposed his bearing and accent were those of a gentleman, and that was enough. People saw what they wanted to see, and when a former officer (who never quite got around to sharing his name) came bearing gifts†¦ No one ever wanted to question it. And through all this, he'd told no one. Who had there been to tell? Grace. Now there was Grace. He smiled. She would approve. Perhaps not of the means, but certainly of the end. The truth was, he'd never taken anything from anyone who hadn't looked as if they could afford it. And he'd always been careful to more thoroughly rob the most annoying of his victims. Such scruples would not have kept him from the gallows, but it had always made him feel a bit better about his chosen profession. He heard a horse draw up next to his, and when he turned, there was Thomas, now keeping pace beside him. â€Å"Is this the road?† he asked quietly. Jack nodded. â€Å"Just around the bend.† â€Å"They are not expecting you, are they?† â€Å"No.† Thomas had far too much tact to question him further, and indeed, he allowed his mount to fall back by half a length, granting Jack his privacy. And then there it was. Cloverhill. Just as he'd remembered it, except maybe the vines had taken over a bit more of the brick facade. The rooms were lit, and the windows shone with warmth. And even though the only sounds were those made by the traveling party, Jack could swear he could hear laughter and merriment seeping out through the walls. Dear God, he'd thought he'd missed it, but this†¦ This was something more. This was an ache, a true, pounding pain in his chest; an empty hole; a sob, forever caught in his throat. This was home. Jack wanted to stop, to take a moment to gaze at the graceful old house, but he heard the carriage drawing closer and knew that he could not keep everyone at bay while he indulged his own nostalgia. The last thing he wanted was for the dowager to barge in ahead of him (which he was quite certain she would do), so he rode up to the entrance, dismounted, and walked up the steps on his own. He closed his eyes and drew a long breath, and then, since he wasn't likely to amass any more courage in the next few minutes, he lifted the brass knocker and brought it down. There was no immediate reply. This was not a surprise. It was late. They were unexpected. The butler might have retired for the night. There were so many reasons they should have got rooms in the village and made their way to Cloverhill in the morning. He didn't want – The door opened. Jack held his hands tightly behind his back. He'd tried leaving them at his sides, but they started to shake. He saw the light of the candle first, and then the man behind it, wrinkled and stooped. â€Å"Master Jack?† Jack swallowed. â€Å"Wimpole,† he said. Good heavens, the old butler must be nearing eighty, but of course his aunt would have kept him on, for as long as he wished to work, which, knowing Wimpole, would be until the day he died. â€Å"We were not expecting you,† Wimpole said. Jack tried for a smile. â€Å"Well, you know how I like a surprise.† â€Å"Come in! Come in! Oh, Master Jack, Mrs. Audley will be so pleased to see you. As will – † Wimpole stopped, peering out the door, his wizened old eyes creasing into a squint. â€Å"I am afraid that I brought a few guests,† Jack explained. The dowager had already been helped down from the carriage, and Grace and Amelia were right behind her. Thomas had grabbed onto his grandmother's arm – hard, from the looks of it – to give Jack a few moments alone, but the dowager was already showing signs of impending outrage. â€Å"Wimpole?† came a feminine voice. â€Å"Who is here at this hour?† Jack stood stiffly, hardly able to breathe. It was his aunt Mary. She sounded exactly the same. It was as if he'd never left†¦ Except it wasn't. If he'd never left, his heart wouldn't be pounding, his mouth wouldn't be dry. And most of all, he wouldn't feel so bloody terrified. Scared spitless at seeing the one person who had loved him his entire life, with her whole heart and without condition. â€Å"Wimpole? I – † She'd rounded the corner and was staring at him like a ghost. â€Å"Jack?† â€Å"In the flesh.† He tried for a jovial tone but couldn't quite manage it, and deep inside, down where he kept his blackest moments, he wanted to cry. Right there, in front of everyone, it was twisting and writhing inside of him, bursting to get out. â€Å"Jack!† she cried out, and she hurled herself forward, throwing her arms around him. â€Å"Oh, Jack. Jack, my dear sweet boy. We've missed you so.† She was covering his face with kisses, like a mother would her son. Like she should have been able to do for Arthur. â€Å"It is good to see you, Aunt Mary,† he said. He pulled her tight then and buried his face in the crook of her neck, because she was his mother, in every way that mattered. And he'd missed her. By God, he'd missed her, and in that moment it did not matter that he'd hurt her in the worst way imaginable. He just wanted to be held. â€Å"Oh, Jack,† she said, smiling through her tears, â€Å"I ought to horsewhip you for staying away so long. Why would you do such a thing? Don't you know how worried we were? How – â€Å" â€Å"Ahem.† Mary stopped and turned, still holding Jack's face in her hands. The dowager had made her way to the front entrance and was standing behind him on the stone steps. â€Å"You must be the aunt,† she said. Mary just stared at her. â€Å"Yes,† she finally replied. â€Å"And you are†¦?† â€Å"Aunt Mary,† Jack said hastily, before the dowager could speak again, â€Å"I am afraid I must introduce you to the dowager Duchess of Wyndham.† Mary let go of him and curtsied, stepping aside as the dowager swept past her. â€Å"The Duchess of Wyndham?† she echoed, looking at Jack with palpable shock. â€Å"Good heavens, Jack, couldn't you have sent notice?† Jack smiled tightly. â€Å"It is better this way, I assure you.† The rest of the traveling party came forward at that moment, and Jack completed the introductions, trying not to notice his aunt going from paler to palest after he identified the Duke of Wyndham and the Earl of Crowland. â€Å"Jack,† she whispered frantically, â€Å"I haven't the rooms. We have nothing grand enough – â€Å" â€Å"Please, Mrs. Audley,† Thomas said with a deferential bow, â€Å"do not put yourself out on my accord. It was unforgivable for us to arrive without notice. I would not expect you to go to any great lengths. Although† – he glanced over at the dowager, who was standing in the hall with a sour look on her face – â€Å"perhaps your finest room for my grandmother. It will be easier for everyone.† â€Å"Of course,† Mary said quickly. â€Å"Please, please, it's chilly. You must all come inside. Jack, I do need to tell you – â€Å" â€Å"Where is your church?† the dowager demanded. â€Å"Our church?† Mary asked, looking to Jack in confusion. â€Å"At this hour?† â€Å"I do not intend to worship,† the dowager snapped. â€Å"I wish to inspect the records.† â€Å"Does Vicar Beveridge still preside?† Jack asked, trying to cut the dowager off. â€Å"Yes, but he will surely be abed. It's half nine, I should think, and he is an early riser. Perhaps in the morning. I – â€Å" â€Å"This is a matter of dynastic importance,† the dowager cut in. â€Å"I don't care if it's after midnight. We – â€Å" â€Å"I care,† Jack cut in, silencing her with an icy expression. â€Å"You are not going to pull the vicar out of bed. You have waited this long. You can bloody well wait until morning.† â€Å"Jack!† Mary gasped. She turned to the dowager. â€Å"I did not raise him to speak this way.† â€Å"No, you didn't,† Jack said, which was the closest he was going to come to an apology while the dowager was staring him down. â€Å"You were his mother's sister, weren't you?† the dowager said. Mary looked a bit baffled at the sudden change of topic. â€Å"I am.† â€Å"Were you present at her wedding?† â€Å"I was not.† Jack turned to her in surprise. â€Å"You weren't?† â€Å"No. I could not attend. I was in confinement.† She gave Jack a rueful look. â€Å"I never told you. It was a stillbirth.† Her face softened. â€Å"Just one of the reasons I was so happy to have you.† â€Å"We shall make for the church in the morning,† the dowager announced, uninterested in Mary's obstetrical history. â€Å"First thing. We shall find the papers and be done with it.† â€Å"The papers?† Mary echoed. â€Å"Proof of the marriage,† the dowager bit off. She looked upon Mary with icy condescension, then dismissed her with a flick of her head, adding, â€Å"Are you daft?† It was a good thing Thomas pulled her back, because Jack would have gone for her throat. â€Å"Louise was not married in the Butlersbridge church,† Mary said. â€Å"She was married at Maguiresbridge. In County Fermanagh, where we grew up.† â€Å"How far is that?† the dowager demanded, trying to yank her arm free of Thomas's grasp. â€Å"Twenty miles, your grace.† The dowager muttered something quite unpleasant. Jack could not make out the exact words, but Mary blanched. She turned to him with an expression nearing alarm. â€Å"Jack? What is this all about? Why do you need proof of your mother's marriage?† He looked at Grace, who was standing a bit behind his aunt. She offered him a tiny nod of encouragement, and he cleared his throat and said, â€Å"My father was her son.† Mary looked over at the dowager in shock. â€Å"Your father†¦John Cavendish, you mean†¦Ã¢â‚¬  Thomas stepped forward. â€Å"May I intercede?† Jack felt exhausted. â€Å"Please do.† â€Å"Mrs. Audley,† Thomas said, with more dignity and collection than Jack could ever have imagined, â€Å"if there is proof of your sister's marriage, then your nephew is the true Duke of Wyndham.† â€Å"The true Duke of – † Mary covered her mouth in shock. â€Å"No. It's not possible. I remember him. Mr. Cavendish. He was – † She waved her arms in the air as if trying to describe him with gestures. Finally, after several attempts at a more verbal explanation, she said, â€Å"He would not have kept such a thing from us.† â€Å"He was not the heir at the time,† Thomas told her, â€Å"and had no reason to believe he would become so.† â€Å"Oh, my heavens. But if Jack is the duke, then you – â€Å" â€Å"Are not,† he finished wryly. â€Å"I am sure you can imagine our eagerness to have this settled.† Mary stared at him in shock. And then at Jack. And then looked as if she very much wanted to sit down. â€Å"I am standing in the hall,† the dowager announced haughtily. â€Å"Don't be rude,† Thomas chided. â€Å"She should have seen to – â€Å" Thomas shifted his grip on her arm and yanked her forward, brushing right past Jack and his aunt. â€Å"Mrs. Audley,† he said, â€Å"we are most grateful for your hospitality. All of us.† Mary nodded gratefully and turned to the butler. â€Å"Wimpole, would you – â€Å" â€Å"Of course, ma'am,† he said, and Jack had to smile as he moved away. No doubt he was rousing the housekeeper to have her prepare the necessary bedrooms. Wimpole had always known what Aunt Mary needed before she'd had to utter the words. â€Å"We shall have rooms readied in no time,† Mary said, turning to Grace and Amelia, who were standing off to the side. â€Å"Would the two of you mind sharing? I don't have – â€Å" â€Å"It is no trouble at all,† Grace said warmly. â€Å"We enjoy each other's company.† â€Å"Oh, thank you,† Mary said, sounding relieved. â€Å"Jack, you shall have to take your old bed in the nursery, and – oh, this is silly, I should not be wasting your time here in the hall. Let us retire to the drawing room, where you may warm yourselves by the fire until your rooms are ready.† She ushered everyone in, but when Jack made to go, she placed her hand on his arm, gently holding him back. â€Å"We missed you,† she said. He swallowed, but the lump in his throat would not dislodge. â€Å"I missed you, too,† he said. He tried to smile. â€Å"Who is home? Edward must have – â€Å" â€Å"Married,† she finished for him. â€Å"Yes. As soon as we were out of mourning for Arthur. And Margaret soon after. They both live close by, Edward just down the lane, Margaret in Belturbet.† â€Å"And Uncle William?† Jack had last seen him at Arthur's funeral. He'd looked older. Older, and tired. And stiff with grief. â€Å"He is well?† Mary was silent, and then an unbearable sorrow filled her eyes. Her lips parted but she did not speak. She did not need to. Jack stared at her in shock. â€Å"No,† he whispered, because it could not be true. He was supposed to have had a chance to say he was sorry. He'd come all the way to Ireland. He wanted to say he was sorry. â€Å"He died, Jack.† Mary blinked several times, her eyes glistening. â€Å"It was two years ago. I didn't know how to find you. You never gave us an address.† Jack turned, taking a few steps toward the rear of the house. If he stayed where he was, someone could see him. Everyone was in the drawing room. If they looked through the doorway, they would see him, struck, ready to cry, maybe ready to scream. â€Å"Jack?† It was Mary, and he could hear her steps moving cautiously toward him. He looked up at the ceiling, taking a shaky, open-mouthed breath. It didn't help, but it was all he could manage. Mary laid her hand on his arm. â€Å"He told me to tell you he loved you.† â€Å"Don't say that.† It was the one thing he couldn't hear. Not just now. â€Å"He did. He told me he knew you would come home. And that he loved you, and you were his son. In his heart, you were his son.† He covered his face with his hands and found himself pressing tight, tighter, as if he could squeeze this all away. Why was he surprised? There was no reason he should be. William was not a young man; he'd been nearly forty when he married Mary. Did he think that life would have stood still in his absence? That no one would have changed, or grown†¦or died? â€Å"I should have come back,† he said. â€Å"I should have – Oh, God, I'm such an idiot.† Mary touched his hand, pulled it gently down and held it. And then she pulled him out of the hall, into the nearest room. His uncle's study. Jack walked over to the desk. It was a hulking, behemoth of a thing, the wood dark and scuffed and smelling like the paper and ink that always lain atop it. But it had never been imposing. Funny, he'd always liked coming in here. It seemed odd, really. He'd been an out of doors sort of boy, always running and racing, and covered in mud. Even now, he hated a room with fewer than two windows. But he had always liked it here. He turned to look at his aunt. She was standing in the middle of the room. She'd closed the door most of the way and set her candle down on a shelf. She turned and looked back at him and said, very softly, â€Å"He knew you loved him.† He shook his head. â€Å"I did not deserve him. Or you.† â€Å"Stop this talk. I won't hear it.† â€Å"Aunt Mary, you know†¦Ã¢â‚¬  He put his fisted hand to his mouth, biting down on his knuckle. The words were there, but they burned in his chest, and it was so damned hard to speak them. â€Å"You know that Arthur would not have gone to France if not for me.† She stared at him in bewilderment, then gasped and said, â€Å"Good heavens, Jack, you do not blame yourself for his death?† â€Å"Of course I do. He went for me. He would never have – â€Å" â€Å"He wanted to join the army. He knew it was that or the clergy, and heaven knows he did not want that. He'd always planned – â€Å" â€Å"No,† Jack cut in, with all the force and anger in his heart. â€Å"He hadn't. Maybe he told you he had, but – â€Å" â€Å"You cannot take responsibility for his death. I will not let you.† â€Å"Aunt Mary – â€Å" â€Å"Stop! Stop it!† The heels of her hands were pressed against her temples, her fingers wrapping up and over her skull. More than anything, she looked as if she were trying to shut him out, to put a stop to whatever it was he was trying to tell her. But it had to be said. It was the only way she would understand. And it would be the first time he'd uttered the words aloud. â€Å"I cannot read.† Three words. That's all it was. Three words. And a lifetime of secrets. Her brow wrinkled, and Jack could not tell – did she not believe him? Or was it simply that she thought she'd misheard? People saw what they expected to see. He'd acted like an educated man, and so that was how she'd seen him. â€Å"I can't read, Aunt Mary. I've never been able to. Arthur was the only one who ever realized.† She shook her head. â€Å"I don't understand. You were in school. You were graduated – â€Å" â€Å"By the skin of my teeth,† Jack cut in, â€Å"and only then, with Arthur's help. Why do you think I had to leave university?† â€Å"Jack†¦Ã¢â‚¬  She looked almost embarrassed. â€Å"We were told you misbehaved. You drank too much, and there was that woman, and – and – that awful prank with the pig, and – Why are you shaking your head?† â€Å"I didn't want to embarrass you.† â€Å"You think that wasn't embarrassing?† â€Å"I could not do the work without Arthur's help,† he explained. â€Å"And he was two years behind me.† â€Å"But we were told – â€Å" â€Å"I'd rather have been dismissed for bad behavior than stupidity,† he said softly. â€Å"You did it all on purpose?† He dipped his chin. â€Å"Oh, my God.† She sank into a chair. â€Å"Why didn't you say something? We could have hired a tutor.† â€Å"It wouldn't have helped.† And then, when she looked up at him in confusion he said, almost helplessly, â€Å"The letters dance. They flip about. I can never tell the difference between a d and a b, unless they are uppercase, and even then I – â€Å" â€Å"You're not stupid,† she cut in, and her voice was sharp. He stared at her. â€Å"You are not stupid. If there is a problem it is with your eyes, not your mind. I know you.† She stood, her movements shaky but determined, and then she touched his cheek with her hand. â€Å"I was there the moment you were born. I was the first to hold you. I have been with you for every scrape, every tumble. I have watched your eyes light, Jack. I have watched you think. â€Å"How clever you must have been,† she said softly, â€Å"to have fooled us all.† â€Å"Arthur helped me all through school,† he said as evenly as he was able. â€Å"I never asked him to. He said he liked – † He swallowed then, because the memory was rising in his throat like a cannonball. â€Å"He said he liked to read aloud.† â€Å"I think he did like that.† A tear began to roll down her cheek. â€Å"He idolized you, Jack.† Jack fought the sobs that were choking his throat. â€Å"I was supposed to protect him.† â€Å"Soldiers die, Jack. Arthur was not the only one. He was merely†¦Ã¢â‚¬  She closed her eyes and turned away, but not so fast that Jack didn't see the flash of pain on her face. â€Å"He was merely the only one who mattered to me,† she whispered. She looked up, straight into his eyes. â€Å"Please, Jack, I don't want to lose two sons.† She held out her arms, and before Jack knew it, he was there, in her embrace. Sobbing. He had not cried for Arthur. Not once. He'd been so full of anger – at the French, at himself – that he had not left room for grief. But now here it was, rushing in. All the sadness, all the times he'd witnessed something amusing and Arthur had not been there to share it with. All the milestones he had celebrated alone. All the milestones Arthur would never celebrate. He cried for all of that. And he cried for himself, for his lost years. He'd been running. Running from himself. And he was tired of it. He wanted to stop. To stay in one place. With Grace. He would not lose her. He did not care what he had to do to ensure their future, but ensure it he would. If Grace said that she could not marry the Duke of Wyndham, then he would not be the Duke of Wyndham. Surely there was some measure of his destiny that was still under his control. â€Å"I need to see to the guests,† Mary whispered, pulling gently away. Jack nodded, wiping the last of his tears from his eyes. â€Å"The dowager†¦Ã¢â‚¬  Good lord, what was there to say about the dowager, except: â€Å"I'm so sorry.† â€Å"She shall have my bedchamber,† Mary said. Normally Jack would have forbidden her to give up her room, but he was tired, and he suspected she was tired, and tonight seemed like the perfect time to put ease before pride. And so he nodded. â€Å"That is very kind of you.† â€Å"I suspect it's something closer to self-preservation.† He smiled at that. â€Å"Aunt Mary?† She'd reached the door, but she stopped with her hand on the knob, turning back around to face him. â€Å"Yes?† â€Å"Miss Eversleigh,† he said. Something lit in his aunt's eyes. Something romantic. â€Å"Yes?† â€Å"I love her.† Mary's entire being seemed to warm and glow. â€Å"I am so happy to hear it.† â€Å"She loves me, too.† â€Å"Even better.† â€Å"Yes,† he murmured, â€Å"it is.† She motioned toward the hall. â€Å"Will you return with me?† Jack knew he should, but the evening's revelations had left him exhausted. And he did not want anyone to see him thus, his eyes still red and raw. â€Å"Would you mind if I remained here?† he asked. â€Å"Of course not.† She smiled wistfully and left the room. Jack turned back toward his uncle's desk, running his fingers slowly along the smooth surface. It was peaceful here, and the Lord knew, he needed a spot of peace. It was going to be a long night. He would not sleep. There was no sense in trying. But he did not want to do anything. He did not want to go anywhere, and most of all, he did not want to think. For this moment†¦for this night†¦he just wanted to be. Grace liked the Audleys' drawing room, she decided. It was quite elegant, decorated in soft tones of burgundy and cream, with two seating areas, a writing desk, and several cozy reading chairs in the corners. Signs of family life were everywhere – from the stack of letters on the desk to the embroidery Mrs. Audley must have abandoned on the sofa when she'd heard Jack at the door. On the mantel sat six miniatures in a row. Grace walked over, pretending to warm her hands by the fire. It was their family, she instantly realized, probably painted fifteen years ago. The first was surely Jack's uncle, and the next Grace recognized as Mrs. Audley. After that was†¦Good heavens, was that Jack? It had to be. How could someone change so little? He looked younger, yes, but everything else was the same – the expression, the sly smile. It nearly took her breath away. The other three miniatures were the Audley children, or so Grace assumed. Two boys and one girl. She dipped her head and said a little prayer when she reached the younger of the boys. Arthur. Jack had loved him. Was that what he was talking about with his aunt? Grace had been the last to enter the drawing room; she'd seen Mrs. Audley pull him gently through another doorway. After a few minutes the butler arrived, announcing that their rooms had been prepared, but Grace loitered near the fireplace. She was not ready to leave this room. She was not sure why. â€Å"Miss Eversleigh.† She looked up. It was Jack's aunt. â€Å"You walk softly, Mrs. Audley,† she said. â€Å"I did not hear you approach.† â€Å"That one is Jack,† Mrs. Audley said, reaching out and removing his miniature from the mantel. â€Å"I recognized him,† Grace murmured. â€Å"Yes, he is much the same. This one is my son Edward. He lives just down the lane. And this is Margaret. She has two daughters of her own now.† Grace looked at Arthur. They both did. â€Å"I am sorry for your loss,† Grace finally said. Mrs. Audley swallowed, but she did not seem to be near tears. â€Å"Thank you.† She turned then, and took Grace's hand in hers. â€Å"Jack is in his uncle's study. At the far end of the hall, on the right. Go to him.† Grace's lips parted. â€Å"Go,† Mrs. Audley said, even more softly than before. Grace felt herself nod, and before she'd had time to consider her actions, she was already in the hall, hurrying down toward the end. To the door on the right. â€Å"Jack?† she said softly, pushing the door open a few inches. He was sitting in a chair, facing the window, but he turned quickly and stood at the sound of her voice. She let herself in and closed the door gently behind her. â€Å"Your aunt said – â€Å" He was right there. Right there in front of her. And then her back was against the door, and he was kissing her, hard, fast, and – dear God – thoroughly. And then he stepped away. She couldn't breathe, she could barely stand, and she knew she could not have put together a sentence if her life had depended on it. Never in her life had she wanted anything as much as she wanted this man. â€Å"Go to bed, Grace.† â€Å"What?† â€Å"I cannot resist you,† he said, his voice soft, haggard, and everything in between. She reached toward him. She could not help it. â€Å"Not in this house,† he whispered. But his eyes burned for her. â€Å"Go,† he said hoarsely. â€Å"Please.† She did. She ran up the stairs, found her room, and crawled between her sheets. But she shivered all night. She shivered and she burned.

Interview a Professor

If freshmen can make a personal connection with Just one faculty member, their chances for success at JUS are vastly improved. Therefore, this professor interview is designed to get you talking to one of your professors outside the classroom. Make the interview into a conversation. If you see this as a quick item of busy work, you will not really get to know the professor. Don't go in, ask the questions, and keep your head down the entire time scribbling notes Instead, really listen to the professors responses and ask follow up questions that interest you.Remember, the goal of the roofless interview is to get to know one of your professors, not to write down his or her exact words. Don't worry about taking down every word your professor says instead, take some notes on key ideas. If you truly listen to the professors responses, you'll remember all you need to write up the interview questions afterwards. To free you up even more to listen and interact with your professor, you might co nsider recording the conversation with a device like your cell phone and then transcribing the interview later.However, before recording, always ask the professors permission iris Believe it or not, but professors were once students too, so take the time to really get to know this professor and what insight he or she can give that might help guide you through your own college experience. This should be a professor who you interact with in some way (advisor, class Instructor, faculty advisor of an organization, etc. ). This assignment should be completed In a face-etc;-face meeting Interview Questions 1. Name of professor. 2. What Is the name of the department In which the professor teaches 3. What courses does the professor teach 4.What Is the professors favorite course to teach 5. What Is the reason the professor chose this area In which to major 6. What degrees did the professor earn From what schools 7. How has higher education changed since the professor was In college 8. What a re the professors Interests, hobbles, recreational actively, etc. 9. What Is the professors favorite book, TV program, movie, etc. 10. What Is the professors Idea of an Ideal student Why 11. What kind of student was the professor 12.

Police Corruption

Drug-Related Police Corruption: An Increasing Problem Throughout Law Enforcement Agencies In The United States In the United States, drug-related police corruption is becoming an increasingly, unjustifiable problem throughout the ranks of law enforcement agencies. Many variables exist to explain the reason for their actions, but ultimately, what makes them do it? Knowing how to recognize a corrupted officer or one exhibiting signs of traveling down the wrong path is essential in order to mitigate the problem.Law enforcement leadership also plays a vital role in the identity and prevention of drug-related corruption. Drug-related police corruption is any act by a sworn police officer that is the sale, manufacture, distribution or supporting of drug activities for the personal gain of the officer. Why is this corruption a problem? Many law enforcement officers who are sworn in to protect the lives of our citizens, to abide and uphold the law, are doing the exact opposite, and this is a problem. The purpose of the study is to provide empirical data on cases of drug-related police corruption.It identifies and describes incidents in which police officers are arrested for criminal offenses associated with drug-related corruption. Data was analyzed on 221 drug-related arrest cases of officers employed by police agencies throughout the USA. Findings show that drug-related corruption involves a wide range of criminal offenses and that cocaine is the most prevalent drug. Older officers and those used by large companies are less likely than others to lose their jobs after a drug-related arrest (Philip Stinson, 2013). Drug-related police corruption is a problem that will not go away on its own which is evident by the statistics.The first step in preventing corruption would be to recognize the signs of a corrupted officer. Learn what puts an officer at risk of becoming corrupted, and what makes them defy the law they swore to uphold, protect and defend. Drug corruption is b orn out of police attitudes because if an officer is lacking the right attitude then corruption can become a mainstay for that officer (Cheurprakobkit, 1998). For example, if any officers believe that the enforcement of drug laws is a waste of their time and that they are underpaid, they may accept a bribe from a drug trafficker to allow the trade.This places a little more money in their pocket and allows them not to worry about enforcing a law they may not agree with. Knowing how to identify the signs of a corrupted officer is a necessary step to decreasing the amount of drug-related corruption, and may one day lead to mitigating the issue. What leads law enforcement to corruption? After looking at yearly sales of different drugs in the United States, it was found that weed brings in about $3 billion dollars, heroin $10 billion, and cocaine, a whopping $38 billion dollars annually (Stevens, 1999).If you pay attention to these numbers, you can clearly see how easy it would be for a low paid, frustrated police officer to turn corrupt and help with the sale, transport, or manufacturing of illegal substances. To reduce police corruption, the commissions recommend creating external oversight over the police with a unique focus on integrity, improving recruitment and training, guidance from supervisors of all ranks about integrity, holding all commanders responsible for the misbehavior of subordinates, and changing the organization’s culture to tolerate misbehavior less (Perito, 2011).While drug-related police corruption continues to pose a threat at some level in every law enforcement agency, it does not necessarily mean there is a high percentage of corrupt law enforcement officials. While it is a problem, it could be prevented with proactive steps – observing the actions and lifestyles of these police officers. There is an opportunity for corruption wherever there are drugs present, and no law enforcement official should be above suspicion. Corrupt ion has been identified at the lowest and highest levels. Police Corruption Police corruption is the misuse of police authority for personal gain. Examples include extortion (for example, demanding money for not writing traffic tickets) and bribery (for example, accepting money in exchange for not enforcing the law).The costs of police corruptionPolice corruption carries high costs. First, a corrupt act is a crime. Second, police corruption detracts from the integrity of the police and tarnishes the public image of law enforcement. Third, corruption protects other criminal activity such as drug dealing and prostitution. Protected criminal activities are often lucrative sources of income for organized crime. The causes of police corruptionAccording to the rotten apple theory, corruption is the work of a few, dishonest, immoral police officers. Experts dismiss this theory because it fails to explain why so many corrupt officers become concentrated in some police organizations but not others. Another explanation pinpoints U.S. society's use of the criminal law to enforce morality.Unenforceable laws governing moral standards promote corruption because they provide criminal organizations with a financial interest in undermining law enforcement. Narcotic corruption, for example, is an inevitable consequence of drug enforcement. Providers of these illegal goods and service use part of their profits to bribe the police in order to ensure the continuation of criminal enterprises. Rooting out police corruptionWhen police controls break down and a scandal occurs, special investigating commissions can mobilize public opinion and rally public support for anticorruption and antiviolence reforms. Commissions get information from the police department, pinpoint where the internal controls of the police have failed, and recommend changes in policy. The problem with these commissions is that they usually disappear after finishing their reports. Paul Chevigny asserts that continuing independent auditors would be more effective than commissions. He envisi ons the function of such auditors as investigating a range of police problems, including corruption and  brutality. Prosecuting corrupt police officersSince corruption involves criminal behavior, prosecution of corrupt police officers is possible. Since prosecutors depend on the police to gather evidence and develop cases, however, they often don't want to â€Å"bite the hand that feeds them.† Legislative controlLegislators could reevaluate laws that create the potential for corruption. Such a reassessment would be based on the recognition that a major portion of police corruption is an outgrowth of laws that criminalize drug use, prostitution, and gambling. Any serious attempt to fight police corruption must wrestle with the decriminalization issue. Decriminalization involves removing the criminal label from victimless crimes by legalizing and regulating them. Decriminalization would contribute significantly to improving the police corruption problem. It is doubtful, howev er, that Congress or any state legislature will seriously consider legalizing drugs or any other prohibited goods and services in the near future.

Beach water

The beaches are considered as important recreational resources. The recreational activities performed at beaches involve a physical contact with water, such as sail-boarding and swimming. There is always a risk of having an accidental injury but apart from that people also face major health problems because of the contamination the beach water. The biggest concern is the microbial contamination by microorganisms such as protozoa viruses and bacteria. The extremely dangerous sewage that comes from urban areas has a number of disease causing organisms in it.Storm drains also contribute to microbial contamination because they sometimes bring the pet waste with them and deposit it into the beaches. Humans are exposed to bacteria and dangerous viruses through the ingestion of the contaminated water which occurs through the entry of water from nose, eyes or ears. Some types of illnesses that are associated with the contamination of the water are some respiratory illnesses that are caused b y the entry of contaminated water into the lungs and Gastro-intestinal disorders; caused by the entry of contaminated water into stomach.There are also some infection associated with the beach water contamination which are minor and are caused through the contact of contaminated water with eyes, nose and ears. Fecal Coli-form bacteria are found in the intestinal tracts of animals and are passed out of the body through fecal waste. Fecal waste is present in the sewage and when that poorly treated sewage is drained into the beaches, it contaminates the water. Swimming in the water in which coli-form bacteria is already present, increases the chances for human to develop certain illnesses such as nausea, stomach cramps, hepatitis and typhoid fever.One way to fight with the fecal coli-form bacteria is to wash with soap after swimming in the contaminated water. In order to save people from the contaminated water there was a treaty signed by the United States and Canada, Great Lakes Water Quality Agreement. It argues that â€Å"recreational waters should be substantially free from bacteria, fungi, and viruses that may produce enteric disorders or eye, ear, nose, throat and skin infections or other human diseases and infections† (EPA, Para. 5). To prevent the recreational water from being contaminated, there are many water quality control programs conducted in every state.Microbial standard exceedances are used to measure the risks associated with the contaminated recreational water but â€Å"due to the limitations in frequency comparison of exceedances it’s been a challenge to evaluate the recreational water quality† (EPA, Para. 9). (NRDC) National Resources Defense Council’s watch dog monitors the quality of beach water and warns the authorities to take actions. â€Å"NRDC identified 131 beaches in 23 states that violated public health standards† (NRDC, Para. 4). The most important challenge that we face is that the water quality standards recommended by EPA are said to be 20 years old.They do not meet today’s health standards because there are many other diseases identified now. There is an annual report by NRDC's annual watchdog, â€Å"Testing the Waters: A Guide to Water Quality at Vacation Beaches,† which has called for several improvements in monitoring beach water† (NRDC, Para. 3). Improvement in the treatment of sewage also will help in avoiding the health risks.
