Kanak Shah Economics AS/b David Conquest "Discuss the Effectiveness of Supply Side Policies in Improving UK Economic Performance" Supply side policies are those designed to increase an economy's long-term growth and so increase aggregate supple or production. In terms of a graphical analysis, if supply side policies work, the long run AS (aggregate supply) curve would shift to the right. A number of various policies have been implemented to increase aggregate demand (AD). The first is deregulation. This involves removing laws and regulations which restrict competition. With deregulation, more firms will compete in the industry and the total supply of the good or the service will increase. A good example to look at is airline deregulation. All Europe flight routes were regulated by governments. There was not very much competition. With the introduction of deregulation, any airline company can fly on any routes that they bid for e.g. EasyJet and Buzz (all low cost airlines). This increases passenger numbers and there is more aggregate supply in the industry. There are a couple of advantages of deregulation. Less regulation means that fewer regulators need to be employed by the government or local councils. Also less regulation should encourage more competition. However, many rules affecting business were to stop exploitation: is this acceptable nowadays? Another
The hypothesis for this piece of coursework is "Exeter is dealing well with its traffic needs" As shown in the maps on the previous page Exeter is a city in the south-west of England, with areas like Dartmoor which is a national park nearby, Exeter is also surrounded by towns and villages like Topsham, Exmouth, Starcross and Lympstone. At the moment Exeter's population is around 111,000 but is always growing. Exeter has many transport links, including two main train stations and a few more local ones, a successful bus service, many roads in and surrounding Exeter and an international airport. Exeter's main train stations are Central station which is a few minute walk to the city centre and St David's station which is a 15-20 minutes walk or a few minute bus journey. Exeter has more local train station such as St Thomas train station, but these unlike the two main train stations which have trains which travel all around the country only have trains which travel to closer towns or cities. Exeter's main bus service which is Stagecoach, has many routes which enables you to travel around and just past the outskirts of Exeter, Stagecoach also have a Main bus station in Exeter which also has less frequent buses which travel further to place all around England. The last transport link which Exeter has is Exeter's international airport which as well as flying chartered flights also
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
Jose Cree Explore the presentation of revenge in 'Hamlet' Revenge is a key theme in Hamlet. It is not only essential to understanding Hamlet's character, it forms the structure for the whole play, supporting and overlapping other important themes that arise. Though it is Hamlets revenge that forms the basis for the story, tied into this is the vengeance of Laertes and Fortinbras, whose situations in many ways mirror Hamlets' own. By juxtaposing these avengers, Shakespeare draws attention to their different approaches to the problem of revenge and how they resolve these. The idea of revenge is first introduced by the appearance of the ghost in act 1 Scene 5, and linked to this is the theme of hell and the afterlife. At the end of this scene, Hamlet is irreversibly bound to revenge for the duration of the play, 'speak, I am bound to hear' 'So art thou to revenge'. The ghost appears with the sole aim of using his son to obtain revenge on his brother, and so every word he speaks is designed to enrage Hamlet and stir in him a desire for vengeance. He uses very emotive language to exaggerate the enormity of the crime, and he concentrates Hamlet's attention on the treachery of Claudius. His description of the murder itself demonises Claudius and contains many references to original sin, 'the serpent that did sting thy fathers life now wears his crown.' Hamlet, who has been
. 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
Say 'NO' to Plastic Bags! Gone are the days when our grandmothers used cloth bags and straw baskets to carry the grocery while going around in the market. For small items there were brown or newspaper bags, but now whether you buy clothes, groceries, meat, books or buttons, the shopkeepers only use plastic bags for the items. Have you ever wondered the beneficial and dangerous side of using plastics? I have and I have found that plastics are very harmful to the environment, even though they are very useful to carry things around. You must be wondering how just a plastic bag, can be so detrimental to the environment. Allow me to tell you how. Plastic bags are cheap and are light in weight. They are also water and chemical resistant and require less energy in manufacture.1 These are the advantages of using plastic bags, but above all these benefits they are still very harmful to the environment! Let's begin with a story to give you all an idea what actually happens when you just throw away a plastic bag, without considering what harm it can cause. A young boy asks a shopkeeper for a plastic bag for the items he had bought; not knowing that it would harm the earth for not carrying the items in his hands or pockets. As soon as he arrives at his doorstep, he throws away the "plastic bag" now regarding it as a useless piece of junk. The winds carry the bag into the river and
