Impact of Slope Incline on Cart Roll
Impact of Slope Incline on Cart Roll Parth Mahajan Acceleration Cart The Aim of this practical report is to roll a car on a slope of 15Ã °, 30Ã °, 45Ã °. The Results then used to make a Ticker-tape graph, Displacement-time graphs, and Velocity-Time graphs with the results that have been obtained. This will show the effects on the cart and how the different aspects of the cart can be effected, (such as the Velocity of the cart, Displacement of the cart and the acceleration of the cart.) Ticker-timers will help analyze the carts motion as the dots on the ticker tape can tell various things which include: The displacement of the cart, the time taken for its total journey, the acceleration of the cart and the velocity of the cart. The Incline plane is a tilted surface which an object (in this case a cart) will slide down. The angle of the incline plane is measured from the horizontal surface to the plank used for the cart to roll down. The Greater the incline of the plank results to a greater acceleration while the smaller the incline of the plank will lead to a smaller acceleration. If friction is deduced then at least 2 forces are acted upon an object to move the object, the force of gravity and the normal force. The force of gravity The force of gravity is also known as the weight acts in a downward direction.The normal force The normal force acts in a direction perpendicular to the surface. Galileo had put this to the test and conducted appointment with the inclined planes. After he had completed the prac several times he had observed that the amount of time it took for the ball to roll down the entire length of the ramp equal to double the amount of time it took for the same ball to only roll a quarter of the distance. He had concluded with: If an object is released from rest and gains speed at a steady rate, then the total distance travelled by the object is proportional to the time squared needed for that travel. Ticker Timer, Power Pack, Wires (2), G clamp. Paper Tape, Sticky Tape Wooden Ramp Trolley Find a place to put the wooden ramp. Secure the Ticker timer with a G-clamp to the wooden ramp. Connect the ticker timer to the power pack. (Make sure you connect to the AC ports and have your volts set to 12V) Get some ticker tape, 60 cm should be enough, and attach it to your cart with some tape. Thread the tape through the ticker timer, making sure the tape goes under the carbon paper and not over. Turn the power bank on, which should turn the ticker timer on and let go of the cart. Make sure someone is there to catch the cart or it could damage the cart. Remove the tape from the cart and you should have a ticker tape with multiple blue dots. Do this for each group member Repeat the process for different angles You should do for angles 15Ã °, 30Ã ° and 45Ã °. 15Ã ° Incline The ticker tape for the cart going down a 15Ã ° incline has the least space between the dots out of the 3 inclines tested. This is because the acceleration on the 15Ã ° incline is the least. As the acceleration is the least this means that the velocity would be the smallest at a given time out of the 3 inclines. The shape of the displacement-time graph shows that the cart is accelerating, this can be seen as the graphs gradient is increasing. For the Ticker-Tape Graph, there is a constant increase in the gradient showing that the cart is accelerating at a constant acceleration. Lastly the Velocity-Time Graph the line is mostly the same gradient showing that there is a constant acceleration. 30Ã ° Incline The ticker tape for the cart going down 30Ã ° incline has averagely sized spaces between the dot out of the 3 different inclines tested. The shape of the displacement-time graph is like the 15Ã ° incline graph but this graph picks has a greater gradient in the end and reaches a higher velocity, this is because since the incline is greater than it means there will be more acceleration. For the Ticker-timer graph the spaces between the different parts of the tapes are similar meaning that the gradient is constant. This is the same for Velocity-Time graph, as the gradient varies a little bit but is mainly constant. 45Ã ° Incline The ticker tape for the cart going down a 45Ã ° has the most space meaning that this cart was travelling the fastest out of all the three carts. The shape of the Displacement-Time Graph for the 45Ã ° incline has the biggest gradient out of the three meaning that it had reached the highest velocity out of the three. The shape of the Ticker-Timer is having a steady increase in the velocity meaning it had constant acceleration. This can be seen in the Velocity-Time Graph. The Gradient of the Displacement-time graph shown the velocity of the cart, since the line is a curved line to find the gradient tangent would need to be calculated to find the instantaneous velocity. The gradient of a Velocity-Time graph shows the acceleration of the cart. Ã Ã When all 9 graphs are compared, it can be seen that the greater the incline means the create the velocity reached and the greater the acceleration of the cart. The results for this prac can vary within the classroom as of human error, the angles measured werent 100% accurate meaning that there could be variations for the angles which leads to variations of the speed reached by the carts. This Prac had been completed successfully and without any major errors. It was learnt that in an Incline is plane is a tilted surface which an object will slide down, it was also learnt that the angle of the incline is measured from the horizontal surface to the planked used.Ã Galileo had put this to the test and conducted various experiments using the incline plane. Improvements that could be made are that the measuring of the angle could greatly be more accurate as the protractors used for the prac were just rough estimates for the angle.

Education Fiesta :: Technology Internet Technological Essays
Education Fiesta In Todayââ¬â¢s competitive society, we all strive for the ideal occupation, and the best learning skills. Technology is a prevalent tool for us, and the Internet especially has helped bring about efficiency. Distance education is not something that I have personally experienced, but through various information sources, I now am fully aware of what online education is all about. To put my research into play I chose to narrate a scenario in which the authors of the sources I used came to my house for a dinner party. Then I provided my own ideas in an analysis of the facts that these authors presented. I tied it up with a personal reflection of everything that I learned. My dining room table pushed against the wall, buffet style, with steaming chaffing dishes, a basket of assorted fresh baked breads, a caddy filled with festive cutlery, pretty napkins laid out in a crescent shaped pattern, and various plates and bowls with the evenings fixings, anxiously I awaited my five guests of honor for tonightââ¬â¢s dinner: Pam Dixon, Emily Weiner, Marcia Williams, Kenneth Paprock, and Barbara Covington; all experts on the topic and field of distance education. They were to arrive at seven oââ¬â¢ clock, which was in ten minutes. I meticulously set up a table of beverages, and a bucket of ice. I also invited a few of my own friends and family members who were interested and about the subject, and wanted more information about online learning. My mother, who is considering finishing up her degree online, my aunt and uncle who are both in the field of computer technology and programming, my neighbor who is also doing research for school on online lea rning, and my friend Lauren who had just decided to come for the discussion, information and appetizing meal. I finished up some last minute preparation work, as the arrival time of my guests got closer. Distance learning is an alternative method of education in our society, which values time and convenience. Online learning, although not a tangible way to attend a university, allows those with families, people with busy lives, those with jobs, those with physical disabilities, and those who do not have access to universities or the right classes to learn the r skills they need, and attain the right degree, in order to work in our field of choice.

Essay on Enzymes Ph and Hydrogen Peroxide
Essay on Enzymes Ph and Hydrogen Peroxide Essay on Enzymes: Ph and Hydrogen Peroxide Investigating a factor that affects the rate if enzyme activity S(a) Possible Independent Variables * Concentration of substrate ââ¬â different concentrations of the substrate can have an effect on the rate of reaction due to more particles in the solution therefore increasing chance of the particles colliding. * pH ââ¬â different pH levels can have an effect on the rate of reaction due to the interference of bonds that hold the enzyme together in the active site. Therefore the specific substrate will not fit into the active site * Temperature - the temperature can have an effect on the rate of reaction. This is because when a substance is heated the particles will move faster therefore increasing the chance of collisions between the particles. * Concentration of enzyme ââ¬â different concentrations of the enzyme can have an effect on the rate of reaction due to more particles in the solution therefore increasing the chance of the particles colliding. * Source of catalase ââ¬â depending on the source of catalase you are using can also have an effect on the rate of reaction. There are many different sources of catalase such as potato, liver and spinach. Depending on which source you are using for your catalase can produce different results. I have chosen to investigate the effect of changing the concentration of enzyme on the rate of catalase activity. I have chosen this independent variable because it will be easy to monitor and change considering that the experiment is kept as fair as possible. It is also easy to measure with the equipment that is available to us. Hypothesis I predict using the information researched that the rate of reaction for the enzyme will be directly proportional to the enzyme concentration. I think the optimum rate of reaction will depend on the enzyme concentration. This is because enzymes can only react with a specific amount of substrate at a given amount of time. Therefore if you were to decrease the amount of enzyme concentration then the reaction would take longer. This is due to the fact that there will not enough particles to react with the substrate. For example if I put in 2g of potato then the reaction will be slower than if I put in 20g, which will then react faster. Variables Independent Concentration of enzyme Dependent Volume of oxygen (cm3) Control * Volume of hydrogen peroxide (cm3) * Volume of pH buffer solution (cm3) * Temperature of water in the tray * Time (seconds) It is important that all the control variables of the experiment are kept the same. This is to ensure that all of the results are accurate and reliable, and that any changes to the enzyme are caused by the change of the concentration of enzyme and no other factors. This will help to make the experiment a fair test. S(b) Equipment list * Potatoes ââ¬â This is the source of the catalase enzyme. It is important that each sample is taken from the same potato to avoid any variation in catalase levels due to different potatoes. We will be using diced potatoes. This will make it easier to adjust when measuring for the concentration. It will also break open the cells, which releases more enzyme and will speed up the rate of reaction. * Hydrogen Peroxide ââ¬â This is the solution we will be using as the substrate for the catalase. The volume of solution we use will be the same each time. * Safety Goggles and Lab Coats ââ¬â this is to make sure that we protects our eyes and clothes from the hydrogen peroxide and the pH buffers. This is because hydrogen peroxide is a bleaching agent. * Buffer Solutions ââ¬â These are the pH buffers that we will be using. We will be using the level 7 buffer solutions each time. * Boiling Tubes ââ¬â The size and depth of the boiling tube will be kept the same so that the volume of solution will not vary each time we do the experiment. * Delivery Tube ââ¬â The delivery tube will be used to transfer the oxygen in to the measuring cylinder

Free Essays on The Shifting Heart
The Shifting Heartà ¡Ã ¨ This play à ¡Ã §The Shifting Heartà ¡Ã ¨ was set in 1950s, in a community where many people did not accept any migrants. The main, theme of this play shows Bianchi family moved to Australia from Italy and how the issues raised regarding to lifestyles in Australia. The racial discrimination was one of the major issues Bianchi family faced since they moved to Australia. For example, Mr. Wilson who works at the sà ¡Ã §hop, thinks it is amusing to call Mrs. Bianchi, Momma Macaroni. This sees it as discrimination and it is an insult and prejudice. And in Act 1, Momma does not see the other neighbours actions as humorous and retaliates by blocking the sewer with stinking fish. And also there are people who throw rubbish. People do this rather than speak to Momma. They have never spoken for eight years since Bianchi family came to Australia. This because neighbours are obviously jealous that the Bianchi own their home through their hard work, and still other neighbours have to pay for their rant. However, this play reveals that the attitudes in todayà ¡Ã ¦s Australia towards migrants have changed significantly. They are more migrants in Australia compared to back in 1950s. Australia is a multicultural society, which is entirely populated by migration. In the past, people from all other continents migrated to Australia in response to economic opportunity and the need for labour or left in times of drought, depression and two world wars. After World War II, Australia was in need of skilled and labour population for development. At present, 150 different nationalities and 90 different languages are represented in the society.

Health Care Fair Essay Example | Topics and Well Written Essays - 500 words - 1
Health Care Fair - Essay Example People are either self-motivated or needs external motivation in every job / career. Therefore, it is important to ask individuals for what is going to be their source of motivation (Carpenito-Moyet, 2006). What are the reasons for choosing this career, and are these reasons extrinsic or extrinsic? Ità will help clear many things regarding the personality and nature of that individual. The field of healthcare is undergoing some difficulties and challenges. In this regard what role can you play, and how can you contribute towards the betterment of the quality of the services in the healthcare industry? In any profession, a person might come across various issues / incidents / scenarios in which he or she has to act in a vigilant manner (Nursing Careers, 2014). For this reason every person who thinks of adopting nursing as a career should be prepared so that they can efficiently respond to them. Furthermore every person has his / her perspective and adopts some specific approach towards life and how he deals his everyday routine. It is obvious that nurses have a key function of taking care of the patients however it is important to know in what they are looking after them and what strategies they are adopting (Carpenito-Moyet, 2006). Furthermore it is also important to know their approach as sometimes they might also panic and that can endanger and risk the lives of their patients. It is understood that nurses are meant to be caring and helping. These individuals are self-driven towards humanity and public care. It is important to know that there is no forceful element behind their decision and that they are happy with their decision. It should be noted that sometimes most of the individuals are not happy with their careers and are simply doing for money or because of unemployment. This reason contributed towards the increase in patient care and its overall quality (Carpenito-Moyet, 2006). In order to figure out whether the individuals are

Television Interview with Bill Mckibben Essay Example | Topics and Well Written Essays - 1750 words
Television Interview with Bill Mckibben - Essay Example Human being shave not left the earth alone. They are carrying out activities that may significantly change not only the earth but also its climate. In this regard, carbon dioxide has been recognized as the main culprit. In fact, the single activity that would be most likely to have a significant impact on climatic conditions is burning of gas, oil, coal and other fossil fuels. Fossil fuels are made up of carbon and therefore burning them would produce carbon dioxide. Since the early 19th century, when the burning of fossil fuels in large quantities began, the levels of carbon dioxide in the atmosphere have increased by more than thirty percent. This has led to an increase in global temperatures from 1 to 2 degrees Fahrenheit. While this may appear to be a minor and even inconsequential increase in temperatures, it has had devastating effects. Numerous books, journals, essays and magazines have been written to this effect and an equally large number of propositions made on how to salv age the situations to save planet earth or even mitigate the effects. No other book captures more graphically the grim picture pertaining to climate change as Eaarth: Making a Life on a Tough New Planet, by Bill McKibben. The following is an excerpt of a television interview in which Bill McKibben talks about the book in particular and climate change in general. With him is a panel of media pundits (Stanley who is hosting the show, Joyce and Craig) and Richard (from Africa), all bound to express their views on the issue as well. Stanley: Bill, thank you for honoring our invitation and welcome to this show. Quite a lot has been said about climate change and your book has extensively touched on the issue. Please enlighten us on the views expressed in the book. Bill: Thank you Stanley. As you have said, climatic changes have been a major concern more so in the recent times. While most of our governments are flirting with the issue, it is important to acknowledge that the implications o f climate change and global warming are quite severe. Look at the changes that have been experienced in many parts of the world. The environmental news has actually deteriorated. Have we not seen ice caps vanishing, oceans acidifying and crops failing more than we have ever seen in the past? Can our forefathers recognize this earth if they were to rise from their graves? I doubt that. We are no longer living in planet earth as they knew it but rather Eaarth. Unfortunately all this has been caused by insensitive human activity. Craig: With all due respect Bill, donââ¬â¢t you think we are overlooking quite a number of things in this respect. I definitely agree that there has been a significant rise in the temperatures as to cause all those things that you have talked of. However, it is important to acknowledge that we know very little about the environment, pertaining to its history, its current state or even how we can protect and conserve it. The debate that we hold actually over states the level of existing knowledge as well as its certainty. Of course I agree that carbon dioxide levels are increasing in the atmosphere and human activity is actually the main culprit. However, how can you be sure that this is the cause of increase in temperature and the consequent changes while we are in the middle of a natural trend of global warming that kicked of around mid 19th century just when we were emerging from the ââ¬Å"Little Ice Ageââ¬
