The magnitudes of the masses for the gliders before the collision were: mass XA1 is equal to 0.107m, and mass XB1 is equal to 0.101m. The magnitudes after the collision of the masses were: mass XA2 equal to 0.0890m, and mass XB2 equal to 0.0820m. The momentum of the masses before collision were: mass PA1 equal to 0.3737 (kg m/s), and mass PB1 equal to 0.3551(kg m/s). The momentum after collision of the masses were: PA2 equal to 0.3109 (kg m/s), and mass PB2 equal to 0.2886 (kg m/s). When considering the direction of the vectors the area of uncertainty is small when considering the area of both parallelograms of uncertainty, because the overlapping of the parallelograms is only a small portion of each. The momentum was partially conserved within the error range of the parallelograms, or the portion where they overlap.

Conclusions
1. It is necessary that they glide on a cushion of air, so that they can avoid any friction which would slow down their movement and could possibly keep them from colliding. The friction would differ for each mass, and would change all the predicted values. If the masses were not on an air cushion, it is impossible to predict that the two masses would ever collide because of the differing frictions for each mass.

2.If the masses were doubled, the before and after collision velocities would both decrease by a factor of two. Because the gliders would take double the time to get to the same distance for collision as if they were not doubled.(newton’s law)

3.The original assumption of this experiment was that it was an elastic collision because there was no visible deformation or heat loss. After further calculations it…...

The Last Spring

...The last spring I remember once I had someone very dear to me, someone that left deep traces in my life, someone that would live in my heart forever, someone that I will never forget. In order to preserve the memory of this angel, a divine human creature, I devote this story to my friend because her innocence and her fragility has been inspiring me for years. I hope that many people will understand the hidden message once they've read the story. It was a wonderful spring dawning. The air was poisoned with nothing else but the strong smell of the spring flowers and the joy of the birds' songs. We were holding our hands and happily as happy can two little girls be, we were bouncing and jumping in the park. Spring could be seen in our eyes, sunshine could be recognized in our smile. It seemed to us like we were flying in the air as two colourful butterflies from a flower to a flower, each of them more and more beautiful, each of them more and more attracting, as if they were the last days of our lives and each of them was more and more challenging. Smiling faces everywhere, people could envy our happy childhood reflected in the deepness of our sight. We were so excited in those spring rainbows above our heads without knowing that this would be our last spring together, remembered afterwards as the coldest one and the darkest one in my life. It's funny how Marta and I met at a beach resort. We could never imagine that we were going to be inseparable friends.......

Constant Gardener

...the parameters within which this civilization functions. To begin with, it is populated solely with boys—the group of young English schoolboys shot down over the tropical island where the novel takes place. The fact that the characters are only boys is significant: the young boys are only half formed, perched between civilization and savagery and thus embodying the novel’s central conflict. Throughout the novel, Golding’s foundation is the idea that moral and societal constraints are learned rather than innate—that the human tendency to obey rules, behave peacefully, and follow orders is imposed by a system that is not in itself a fundamental part of human nature. Young boys are a fitting illustration of this premise, for they live in a constant state of tension with regard to the rules and regulations they are expected to follow. Left to their own devices, they often behave with instinctive cruelty and violence. In this regard, the civilization established in Lord of the Flies—a product of preadolescent boys’ social instincts—seems endangered from the beginning. In Chapter 1, the boys, still unsure of how to behave with no adult presence overseeing them, largely stick to the learned behaviors of civilization and order. They attempt to re-create the structures of society on their deserted island: they elect a leader, establish a division of labor, and set about systematically exploring the island. But even at this early stage, we see the danger that the boys’ innate......

Constant Gardener

...The fragmented style of "The Constant Gardener" is the best way to tell this story. It is not a story told where the beginning starts with a mystery and ending at truth, but a circling around an elusive conspiracy. In a remote area of Northern Kenya, the passionate Tessa Quayle, played by Rachel Weisz, has been found brutally murdered. Tessa's travelling companion, a local doctor, appears to have fled the scene and the evidence points to a crime of passion. Members of the British High Commission assume that Tessa's widowed husband, Justin Quayle (Ralph Fiennes), will leave the matter to their discretion. Determined to clear his wife's name and "finish what she started", Justin embarks on a crash course to learn about the pharmaceutical industry, whose crimes Tessa was on the verge of uncovering. The film involves drug companies who test their products on the poor of the Third World and are willing to accept the deaths that may occur because, after all, those people don't count. Why not you might ask, no one is there to count them. Film editing could be called 'film construction' and has been regarded by many as the 'invisible' art behind some of the greatest motion picture sequences of all time. Film editing is a skilled art - the selection and integration of a sequence of shots taken from thousands of feet of film to establish a structure, tempo, mood, or style. Editing a films emotional intention of a scene is not realized: you don't laugh at what was intended to be......

Spring

...Hopkins’s poem focuses on the beauty of the spring season, using examples of how life blossoms during the spring. Everything comes to life, the new array of colors paint a colorful world. All of God’s little creatures come to life. Birds fill the air soaring through the bluest sky, they build nest for little newcomers. The spring showers clean the air and everything smells clean and fresh to the poet. This world emerged from a dreary place called winter. Hopkins expresses how spring brings God’s paradise alive once again; and he is elated. Hopkins shows God his appreciation through his expression of how the spring must be similar, to the Garden of Eden. The world feels clean and bright to the Hopkins. Almost seems like a prayer request asking God to make it last forever, unlike the Garden of Eden which brought sorrow and despair. Analysis: Hopkins focuses on bright colors, like the "descending blue, that blue is all in a rush" and also uses similar "like lightning" to reinforce the power of spring. The image he gives the reader catches the reader off guard, a small distraction small distraction. Hopkins states “weeds and wheels” and “long lovely and lush,” this little distraction changes the readers’ visual. However, almost immediately he regains the reader’s attention. With his illustration it only gives the reader the meaning as his imaginary wheel makes you focus on his expression of the spring season here, Hopkins hits a note, he questions nature “”all......

The Constant Gardener

...The Constant Gardener INTRODUCTION Why Fernando Meirelles? Fernando Meirelles’ film is one of a recent batch of Hollywood films dealing with serious issues. In this case the film is a conspiracy thriller, which looks at the involvement of a large pharmaceutical company in testing drugs in Africa. That said, the film is much more, combining a love story, a quest for revenge and expressing real anger about the West’s apparently unchecked exploitation of ordinary African people. The Constant Gardener is an adaptation of a novel by the British writer John le Carré, best known for his tales of spies and Cold War intrigue. Fernando Meirelles seemed an odd choice for director, because of his Brazilian background and the seemingly huge difference between this film and his first feature, the explosive story of a Rio favela, City of God (2003). www.filmeducation.org 1 Mike Newell was the first choice for director, but had already committed himself to the new Harry Potter film, but Meirelles was very interested in the project. He told The Independent, ‘The chance to take on the pharmaceutical industry was one of the three elements that made me want to direct The Constant Gardener, as was the chance to shoot in Kenya. Also, it’s a very original love story about a man who marries a much younger woman who is very different from him, and it’s only after she dies that he truly falls in love with her.’ Meirelles’ Brazilian background gave him a source of empathy with the poverty......

Constant Temptation

...Raven Jones Professor Lee-Harris Composition II 4 February 2015 “Constant Temptation” Social media has become a constant temptation amongst kids and teens. Whether or not social media should be used as a learning tool in the classroom has become a very controversial topic in the education department. Some administrators and educators have gone as far as banning all social media from being used in the classroom and online, while others have not, and find it very useful. Although there address many views on this topic, teachers and students can benefit from using social media in classrooms. Opposing views claim social media is hindering human interaction. It doesn't help or improve a student's a stability to communicate verbally. However, the benefits outweigh the negatives. Allowing students to interact through social media can work on their ability to work together. It allows them to collaborate in and out out of school. For example, a student that is very shy and doesn't feel very comfortable speaking in front of a whole class may feel more comfortable behind the computer screen. Although social media can be a distraction in the classroom, it is also a distraction from everyday life. Students are on social media just about every hour of the day. Therefore, teachers put themselves at an advantage by using social media. Student's can get help with their homework by posting questions online and getting quick responses. Doing so, allows teachers to get feedback on......

The Constant Gardener

...The film ‘The Constant Gardener’ directed by Fernando Meirelles, I agree, is used as a means to critique our society. The character of Justin Quayle, a British High Commission Diplomat, is used by the director to reflect society. We see this in the beginning of the film where his ignorance leads to a false perception of reality, which highlights the 2 major themes in the film of Truth and Perception and Guilt and Atonement. Justin uses gardening as a means to feed this ignorance, just as society itself uses work, family and other matters to hide from the harsh reality. But as his wife Tessa dies under unusual circumstances it leads Justin into the real world, where the truth can no longer be covered up and he must follow the road to atonement. In an early scene of the film, Justin, like society is consciously removed from reality. Before this scene we are shown wide and establishing shots of Lake Tuitakana in Africa where we see mars-like images of the red sands and bright blue water streaked across the landscape. This scene then fades into the British High Commission Embassy, where there is a complete contrast in colours. We instead get a Wide Shot of the building with dull colours of grey and dark greens and blues. This shot also shows Justin “skiving” as he waters his plants. Although he is in charge of Aid distribution in Kenya, he is choosing to remain in his own perfect world “a world with no weeds”, where he stays in the office and has never once gone outside of the......

Spring Motion

...Title: How different springs behave under the influence of same mass depending on the spring constant (k) and connection types (parallel or series)? Summary: This experiment will be carried out to investigate spring constants of different springs by measuring the length of springs under the influence of same mass and different masses, and observe how overall spring constant changes depending on connection types of springs by measuring amount of extension when springs are connected in series and parallel. Different springs with different constant, different masses, weighing machine and a measuring ruler will be used. Research: The course textbook and different textbooks (S.Beichner, Fizik1, Ankara: Palme Yayınevi, 2002.), some laboratory experiments, which retrieved from the Internet, some lectures and videos comprise sources for the theoretical analysis of the experiment. -Prof. Walter Lewin (1999), Hooke's Law, Simple Harmonic Oscillator (online) (http://ocw.mit.edu/courses/physics/8-01-physics-i-classical-mechanics-fall-1999/video-lectures/lecture-10), -Combination of springs (online) (http://engineeronadisk.com/V2/book_modelling/engineeronadisk-10.html) -Sal Khan (2008), Intro to springs and Hooke's Law (online) (http://www.youtube.com/watch?v=ZzwuHS9ldbY) -Forces and elasticity (online) (http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/forces/forceselasticityrev2.shtml) -Deformation of materials (online) (http://qatemplates.everythingscience.co.z...

Constant Change

...“Constant Change” In a world where nothing is constant except change, we are also faced by a dreading fact that as years goes by, our climate is also changing. The way people way people lived today has drastically changed from the way our forefathers lived thousand years ago. The Climate Change or Global Warming has been an issue for so long, but do we really care about our dying world? In the past years, scientific evidence for the warming of the climate system has been tracked down and is very unequivocal. According to National Aeronautics and Space Administration (NASA), these are the signs that we are in a state of a climate change: The sea level rise – global sea level rose about 17 centimeters (6.7 inches) in the last century. Global temperature rise – all three major global surface temperature reconstructions show that Earth has warmed since 1880. Warming Oceans – the oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of 0.302 degrees Fahrenheit since 1969. Shrinking ice sheets – the Greenland and Antarctic ice sheets have decreased in mass. Declining Arctic sea ice – both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades. Glacial retreat – glaciers are retreating almost everywhere around the world – including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa. Ocean acidification – since the beginning of the Industrial Revolution, the acidity of......

Measurement of the Spring Constant

...MEASUREMENT OF THE SPRING CONSTANT TWO METHODS COMPARED ABSTRACT A spring is an elastic object, which can be extended and contracted by forces with a constant elastic coefficient. This report assesses two methods for determining the spring constant of a specific spring. One method uses the length that the spring extends and the masses that are attached to the spring. The other method measuring the spring constant is based on the harmonic motion. INTRODUCTION Spring constant is an instinct property of a spring. The magnitude of a spring constant depends on the material of the spring but not the lengths it extends or contracts or the forces that are applied to the spring. Hook’s law predicts that the length the spring extends or contracts is directly proportional to the force applied by the coefficient of the spring constant. The aim of this experiment is to compare the two measures of finding the value of the spring constant of a spring. MATERIALS AND METHODS METHOD A The spring is hanged on an iron stand. The lengths of the spring, L, are measured when the spring is attached to different masses, M, of metals vertically. The lengths are measured by using a ruler with scales, while the mass attached to the spring can be read from the metal. For better accuracy, five masses are attached during this method. METHOD B The spring is hanged on an iron stand. Different masses, m, attached to the spring can be read from the metals and the time period, t, of the......

...art&scienceresearch methods nursing standard: clinical · research · education Use of constant comparative analysis in qualitative research Hewitt-Taylor J (2001) Use of constant comparative analysis in qualitative research. Nursing Standard. 15, 42, 39-42. Date of acceptance: March 19 2001. Summary This article describes the application of constant comparative analysis, which is one method that can be used to analyse qualitative data. The need for data analysis to be congruent with the overall research design is highlighted. T HE AIM OF qualitative research is to portray the reality of the area under investigation, and to enhance understanding of the situation and the meanings and values attributed to this by individuals; it does not involve the quantification of facts (Rose 1994). Qualitative methods emphasise the value of individual experiences and views, as encountered in real-life situations. This type of investigation is often useful in nursing, as many issues concern the quality of the lived experience of individuals, which cannot be reduced to numerical values using statistical analysis. Sometimes a mixed methodology might be adopted, with elements of qualitative and quantitative enquiry being included in a study. The nature of qualitative enquiry means that volumes of ‘rich’, ‘deep’ data are produced, often from a variety of sources. While not seeking to reduce data to statistical evidence, qualitative data nevertheless requires......
