The spinners investigation Essay Example for Free

The spinners investigation Essay The prediction for this investigation is the shorter the wingspan of the spinner the faster it will fall the 2. 59m to the floor. I think this because with shortening the wingspan Im making the surface area smaller this means less air resistance acting upon it when it is falling. There will be an unbalanced force because gravity will always be the same but the air resistance will get smaller with every half centimetre I cut off, so there will be less area for the air resistance to act upon. The apparatus you need for this experiment are the following things: A paper spinner. A paperclip (to give the spinner some weight) A table to which you can stand on to hold the spinner to the height of 2. 59m (the ceiling) A stop clock A table to record the results (the results are the times taken to reach the floor) In order to make the investigation fair: You will only change the length of the wing span because that is the variable you are using; changing anything else would mean the experiment would be corrupted. The things you have to keep the same are the spinner; you will use the same spinner throughout the experiment. Keep the height the same too. In this investigation you have to count the time taken for the spinner to fall the 2. 59m to the floor from the ceiling and measure the length of the spinner since you change that yourself. When you drop the spinner you take the time taken for it to land using a stop clock, you do this three times and take an average. You can get an exact time taken for it to fall but the stop clock is the best instrument for the job as far as I can decide. The safety issues are important, like when you have to stand on the table to reach the ceiling you should make sure your shoes are suitable and dont have too big a heel. My preliminary work consisted of doing work on unbalanced forces this helped me to come to my prediction about how there would be an unbalanced force acting on the spinner because there would be less air resistance the less surface area there was to act upon. The Method The detailed plan is: To carry out this investigation you would have to do the following: First, you would have to make the spinner, you can make it however you want but there is a spinner for example overleaf. Add a paperclip to give it a little weight. Once the spinner is made you would have to make yourself a results table to fill in. Then you stand on something secure and hold the spinner to the ceiling and have someone ready with a stop clock to press the start button at the precise moment the spinner is dropped from the ceiling and stop the clock once the spinner has reached the floor. As this isnt completely accurate do this three times for every time you change the variable (the wing span). So every time you cut off the half centimetre off the wings (both sides) you should do the particular experiment three times over and find the average. Results Wing Length (cm). Time Taken (s) Time Taken (s) Time Taken (s) Time Taken (s) 1st Time 2nd Time 3rd Time Average   An observation I made during this experiment was when the wingspan got to only 4cm long the amount of air resistance was too small compared to the greater amount of gravity to make the spinner spin and reach a constant speed, it just ended up falling straight to the floor. I didnt change anything through out my investigation. Below is a bar chart of my results and over the page are my results as a line graph. The y-axis is the time taken for the spinner to reach the floor (in seconds) and the x-axis is the length in (centimetres). I have found out through doing this experiment that the smaller the surface area is the quicker something will fall to the floor, this is because the force of gravity doesnt change but as air resistance relies on the surface area and changes to suit the area. If the area is small then the air resistance too is small and if the area is large then the air resistance too is large. This means when the wingspan is smaller the area of the spinner is smaller and with that the air resistance is smaller, smaller than the force of gravity. So if gravity is the larger of the two forces it will pull the spinner to the floor faster and faster as the air resistance gets smaller and smaller. Thats what this investigation has proved. The majority pattern throughout my results is that of, as the surface area of the spinner gets smaller the time taken to reach the floor decreases too. My results and what I have found out match the prediction I made at the beginning before the experiment had been carried out. Evaluation My results or anyone elses can not be 100% accurate because there is always going to be a time delay from when you see the spinner being dropped and when your brain tells your fingers to begin the stop clock. I think I took enough results as I came up with the answer I was looking for and knew was right, but I dont think it would have done much harm doing more results though, but I dont think it would have been necessary to do more. I could have maybe made the range of changing the variable bigger and then do more measurement but then I would have to have made a larger spinner. There was one result that didnt fit into the pattern but I didnt worry too much about it as I had the 2nd and 3rd result to make sure the average wasnt messed up. Also I believe it was just the slow reactions of my partner, starting the stop clock too late after I had dropped the spinner. If I was to repeat this experiment again I would probably try and get a higher height to drop my spinner from I think that would probably improve my results the measurements wouldnt be so small if the height was bigger and that way the graphs would look better and be easier to read. I could also try making spinners out of different materials and see if that affects the time taken to reach the floor any differently.

Critical Prespective Native Son :: essays papers

Critical Prespective Native Son Richard Wright marked the beginning of a new era in black fiction. He was one of the first American writers of his time to confront his readers with the effects of racism. Wright had a way of telling his reader about his own life through his writing. He is best known for his novel, Native Son, which is deeply rooted in his personal life and the times in which he lived. This paper will discuss this outstanding American writer, his highly acclaimed novel, Native Son, and how his life influenced his writing. Richard Nathaniel Wright, was born on September 4, 1908 in Roxie, Mississippi. His father was a sharecropper and his mother a schoolteacher. In search for better employment his father moved the family to Memphis, Tennessee. While in Memphis, his father worked as a night porter in a hotel and his mother worked as a cook for a Caucasian family. Shortly after their move to Memphis, Wright’s father deserted his family. His mother then tried to find any work she could find to support her family. Then, at the age of seven his mother became ill and was unable to financially support her family. As a result, the family had to move to Jackson, Mississippi to live with relatives. Wright remained in Jackson until 1925 (Walker, 13). In 1925, Wright left Jackson and headed as far as his money could take him, and that was Memphis, Tennessee. Memphis was the exact same city in which his father had taken his family to find a better life and where he abandoned them. Wright’s first trip to Memphis ended in disappointment, desertion, and deprivation. While there Wright found work as a messenger for an optical company. He lived in Memphis for approximately two years. During that time, he witnessed the deep and violent South which eventually would permanently scar him for life. Margaret Walker wrote: I am convinced that the best of Richard Wright’s fiction grew out of the first nineteen years of his life. All he ever wrote of great strength and terrifying beauty must be understood in this light. His subjects and themes, his folk references and history, his characters and places come from the South of his childhood and adolescence. His morbid interest in violence-lynching, rape, and murder-goes back to the murky twilight of a southern past. Out of this racial nightmare marked with racial suffering,

Style and Analysis Essay for Soldier

John Ruskin, an English critic of art and society, wrote a passage arguing that we should be giving precedence to the soldier rather than to the merchant or manufacturer. In today’s world many people debate about who deserves to be emphasized in society. Ruskin’s argument is invalid because of his use of generalization, false dilemma, pathos and charged language. He uses a black and white statement to show the difference between soldier and manufacturer and generalization to make it seem as though all soldiers participate for the same reason. The use of pathos and charged language really plays with the reader’s emotions.In Ruskin’s passage he argues that the soldier should be more respected and considered more important than a merchant or manufacturer. Ruskin, directing his passage to the general society, says a soldier would â€Å"put him in a fortress breach, with all the pleasures of the world behind him, and only death and his duty in front of him. â €  This statement, very generalized, uses the logical fallacy of generalization. In this statement John Ruskin describes all the soldiers together as one, instead of individually. Just because all soldiers participate in war, does not mean they all are in favor of death, or dying for their country.For example a man could have joined war and become a soldier because he didn’t have any skills or simply because he enjoys the act of killing, not because he wants to fight for his country. Ruskin, using pathos, says that soldiers give up â€Å"pleasures of the world† and put their â€Å"duty in front. † In this quote Ruskin uses charged words to emotionally involve you. Duty is a strong word that many of us take as another word for responsibility. In some perspectives duty is seen as a law; one must uphold a moral or legal obligation. Putting death before pleasure makes the reader feel obligated to respond with sympathy.Not only does John Ruskin play on our emotion s and guilt us into making soldiers seem more important, he makes a black and white statement about soldiers and merchants/manufacturers. John Ruskin makes a black and white statement by saying soldiers are different from merchants and manufactures because â€Å"men associated for purposes of violence and for purposes of manufacture; in that the former appear capable of self sacrifice. † John Ruskin says that the general public should perceive that merchants/manufacturers are nothing if they don’t have the willingness to sacrifice themselves as soldiers do. The eaders don’t realize that the soldiers would be nothing without the merchants and manufacturers. The soldiers are provided in war, weapons, materials and food†¦but by whom? The manufacturers sacrificed time, materials, and food to support the soldiers. Ruskin is very heavy in using pathos, and once again tries play with the reader’s emotions. Using very well wording to emphasize emotions and c hange our view and perspectives, Ruskin draws out pathos. In the first sentence Ruskin says â€Å"that the former appear capable of self sacrifice. † The word â€Å"capable† portrays as a very strong and demeaning word.It makes readers see the merchants and manufacturers as weak, pathetic and selfish to not have the courage to die for ones country. Ruskin uses pathos, making the readers feel not only guilty and sympathetic, but also proud that they have men willing to fight for their country. John Ruskin’s statement’s about soldiers deserving more precedence is invalid due to the use of logical fallacies. Generalizing people can turn out invalid because all people, whether they do the same things or not, have different interpretations of things. The motivations of the soldiers joining war are unknown and can vary depending on the person.Making a black and white statement can also turnout invalid because there may be shades of gray in between. The merchant s and manufacturers may seem small compared to the soldiers, but in actuality they are doing something just as important as the soldier. Ruskin’s argument is flawed with charged and specific selection of language that plays on the reader’s emotions, causing logic to be unsound. Ruskin’s use of language creates an impression of sympathy for the soldiers. In society, status will always be judged and argued by everyone through different understandings.

The Importance Of Developing Good International...

In the world of business, the importance of developing good international relationship is increasing as technology and competition arises. Today, there is no country that feels self-sufficient enough to not do negotiations with diverse countries across the world. Nevertheless, certain negotiations may experience conflicts while communicating since the agreement is being done by people from different countries. The most common issue that humans experience while communicating with people around the world is the culture since society can sometimes be close minded, meaning that â€Å"people see what they want to see(Riccardi, 2014).† As Pellegrino Riccardi expanded the problem with intercultural communication, he stated the real significance in the definition of culture, which is being in the comfort zone of familiarity and acceptance. In addition, according to Benedict Lee(2015) some of the barriers that affect intercultural communications include â€Å"anxiety, ethnocentrism, assumptions, stereotype and prejudice.† However, there are ways to conquer intercultural communications such as acquiring â€Å"good attitude, being knowledgeable of the other culture, and developing such cultures empathy skills(Lee, 2015).† Communication across cultures will be described by going in deep in the work of Geert Hofstede and examining culture of China and Australia.
