Project in Physics Technical Paper "Making an Electromagnet" Submitted by: Group 10 Audrey Mae Selda Ednard La Rosa Easter Cindy Mutia Ken Bjanli Te Year 4- Diamond Submitted to: Ms. Shella Mae Cascaro Physics Teacher Date of Submission: December 14, 2005 Wednesday A. Statement of the Problem/ Objectives: The following are some objectives or what the proponents would like to carry out in the progress of this project: To be able to make an electromagnet in the simplest way. To be able to relate the number of turns of wire with the strength of the electromagnet To be able to attract as many paper clips as possible. To be able to explain and recognize the principles and concepts behind electromagnetism. B. Materials and Methods: I. Materials: These are some of the materials used by the proponents in making the electromagnet: One iron nail Stranded copper wire One or more D-cell batteries Scissors Paper clips II. Methods: These are what the proponents did in making the electromagnet: The proponents first gathered all the materials needed for the making of the electromagnet. The next thing that the proponents did was to remove some insulation. So a pair of scissor or a cutter was used in order to remove the insulating rubber starting from each end of the wire to expose the copper wire. The wire was wrapped around the nail in a spiral manner.

eBusiness / Kmart Analysis Online Marketing Marketing businesses, products and services has become much more complex with the introduction of the internet. In this paper I will attempt to describe the effect of e-business on marketing strategies today, as well as describe the e-business marketing strategies utilized by Kmart, Inc. The internet is an enormous environment that is advancing and developing at a very erratic pace, and only companies able to adapt will survive. The World Wide Web provides a medium that breaks through geographical boundaries, allows the customer much more control, and has no time restrictions as it is always "open". According to an article by Dr. Ralph F. Wilson, Niche Marketing on the Web, there are three important steps to marketing on the internet; (1) profile your customers, (2) decide where they congregate, and (3) communicate the message where they congregate in a net-acceptable manner (Wilson, 1996). Bluelight.com, Kmart's e-commerce site launched in 1999, is a shining example of this philosophy, having accumulated over 3.5 million customers in less than one year. Although Kmart had an obvious advantage with a n existing strong customer base, these shoppers were not internet customers. In an effort to establish a web based customer segment, they targeted these existing customers by placing Bluelight.com CD ROM's which provided
CRITIACAL EVALUATION "Ambulances" by Philip Larkin uses the every day incident of someone being taken away in an ambulance to convey the ideas of human life. The poem discusses the idea of the closeness of death; it's randomness and its inevitability. I am going to look at how effectively Philip Larkin uses this everyday occurrence to lead to the general or universal statement: death will come to us all at some point no matter who you are. I will show this by discussing the use of word choice, theme and setting. In stanza one, the impression that an accident can happen anywhere at any time is created by the feeling of menace. This is shown by the thought that ambulances can "come to rest at any kerb" suggesting that it doesn't matter where you are an accident can happen. The use of the word "any" helps to emphasise this point and convey the theme of the randomness of death. The idea that death comes to us all is suggested by "All streets in time are visited". The word "All" emphasises the fact that everyone dies, and the word "time" indicates that it is just a matter of time. I think that Larkin wanted to portray the idea that everyone will make their journey in an ambulance at some point. The ambulance is only symbolic for the doorway to death. At the beginning of the stanza the ambulances are described as "closed like confessionals," this sets the feeling inside the

THE MAYOR OF CASTERBRIDGE. "Discuss how the passage of time is presented in the first chapters of The Mayor of Casterbridge. What effect does it have on the characters?" This essay will answer the preceding question by discussing how the key characters and places develop and are affected by the passage of time in the first few chapters of the book. The author of the book is Thomas Hardy, a very descriptive writer, although this is one of his faster paced books. It was written in the 1880's and is set in the 1830's. The book begins with Michael Henchard walking along a dusty road with his wife Susan. She is carrying a baby called Elizabeth -Jane. After getting to the fair taking place in the village Henchard becomes drunk and sells his wife. The next day he regrets what he has done and consequently swears an oath that he will not touch a drop of liquor for 21 years. At this point in the book (chapters 2-3) there is an 18 year gap in the book. The book is set in the summer of around 1830 we know this because "before the 19th century had reached one-third of its span." As it was set in the 1830's the landscape would have been very different from today. This is demonstrated from the start of the book. Michael and Susan Henchard are "plainly but not ill clad" This tells us that they are not badly off. On the other hand they are covered in a "thick hoar of dust" telling us that
7/07/2004 Bilawal Ajmal Khan 10A H/W/K Science Investigation Aim: to investigate the effect of carbon dioxide concentration on the rate of photosynthesis. Scientific knowledge: The Elodea (Canadian pondweed) makes bubbles of oxygen when it photosynthesises. The faster it photosynthesises the faster it makes oxygen. The plant uses dissolved carbon dioxide. This can be made by adding hydrogen carbonate solution to the water. The factors which can effect how quickly a plant can make food by photosynthesis include the following. * Carbon dioxide concentration - this can be simulated by changing the volume of hydrogen carbonate solution added to the water. At low concentrations of carbon dioxide the rate of photosynthesis is very slow. As you increase the concentration of carbon dioxide the plant can make food faster and faster. There is a limit however. There comes a time when adding more carbon dioxide does not increase the rate of photosynthesis. The plant is making food as fast as it can under the conditions. * Light intensity - this can be altered by either changing the brightness of the bulb or by moving the bulb further and further away from the plant. Plants need light energy in order to make food. The more light they have the faster they can make food.
Aim To determine the water potential of a potato tuber cell using varying salt solution. Introduction Osmosis is the diffusion of water molecules from a region where it has higher water potential to a region where it has lower water potential through a partially permeable membrane1. As osmosis is a type of diffusion the same things that affect diffusion have an effect on osmosis some of theses things are: * The concentration gradient - the more the difference in molecules on one side of the membrane compared to the other, the greater the number of molecules passing through the membrane and therefore the faster the rate of diffusion2. * The surface area - the larger the area the quicker the rate of diffusion * The size of the diffusing particles - the smaller the particle the quicker the rate and polar molecules diffuse faster than non-polar ones3. * The temperature - the higher the temperature the more kinetic energy the particles have and so the faster they move. From the diagram4 we can see the process of osmosis in a simple expression. On the right side there is pure water, which has the maximum water potential of 0. Water potential is the pressure created by water. As you can see from the diagram the pure water is pushing its way through the semi permeable membrane at a high pressure. This is its water potential. Water potential is measured in kilopascals (kPa)
To what extent will does correlation and extrapolation assist Nintendo in forecasting sales? (34 marks) Correlation is the relationship between two variables. Extrapolation is related to correlation, as it involves plotting a linear regression curve (also known as a line of best fit) which is based upon how two variables are correlated, and extending the line to predict future values. For Nintendo, a computer game and console manufacturing company, a common example would be the relationship between the level of advertising expenditure and the effect of this on sales of its products. The graph to the left shows a strong positive correlation between sales and advertising, meaning if Nintendo increases its advertising, they can expect to see an increase in sales. Because all values are close to the line, as advertising expenditure increases on the x-axis, sales on the y-axis increase proportionately. The regression line can be extended past the '80' figure (meaning £80million) to predict what sales will be like if they spend £100million or even £900million. The uses of such analysis to Nintendo are to an extent very valuable. By creating a scatter graph like the one above, Nintendo can spot trends and forecast future events. For example, they could estimate demand at a certain point in the coming year. One would expect demand to surge at Christmas time when people are
. Plan Aim To investigate how the length of a simple pendulum affects the time for a complete swing. Variables length The length of the pendulum has a large effect on the time for a complete swing. As the pendulum gets longer the time increases. size of swing Surprisingly, the size of the swing does not have much effect on the time per swing. mass The mass of the pendulum also does not affect the time. air resistance With a small pendulum bob there is very little air resistance. This can easily be seen because it takes a long time for the pendulum to stop swinging, so only a small amount of energy is lost on each swing. A large and light pendulum bob would be affected by a significant amount of air resistance. This might change the way the pendulum moves. gravity The pendulum is moved by the force of gravity pulling on it. On the Moon, where the pull of gravity is less, I would expect the time for each swing to be longer. Theory When the pendulum is at the top of its swing it is momentarily stationary. It has zero kinetic energy and maximum gravitational potential energy. As the pendulum falls the potential energy is transferred to kinetic energy. The speed increases as the pendulum falls and reaches a maximum at the bottom of the swing. Here the speed and kinetic energy are a maximum, and the potential energy is a minimum. As the pendulum rises the
Explain why the depression of 1929 was a 'godsend' for the Nazi Party Of all European countries, none was hit harder than Germany by the stock market crash of October 1929. Germany, who was still suffering from the Treaty of Versailles, had borrowed very large sums from American banks, with much of the money repayable either on demand or at short notice. These loans were of course recalled, and bankruptcies in Germany rose sharply from the start of 1930. Unemployment rose sharply, too. The German economy plummeted with the stock market and the situation Germany found itself in resulted in even more faith being lost in the Weimar constitution. This situation was a godsend for the Nazi Party as it enabled them to gain public support. Having lost faith in what they already felt was an indecisive Government, and after the 'stab in the back' myth having been circulated throughout the country, Germany became increasingly hard to govern. Hitler, an inspiring and energetic speaker, took this opportunity to present himself and the Nazi party to the German people. Showing himself as a strong leader, he promised to abolish the Treaty of Versailles and restore Germany to power. This was one of the ways in which the Great Depression aided the Nazis. Because of the people of Germany falling into poverty and despair and being eager for help, Hitler's talk of a new Germany and his
