British Mercantilism Essay -- essays research papers
Economic ideas and systems come and go. Many systems have failed and many have succeeded. The British system of mercantilism was actually quite a good system for England. They raked in profits from their colonies. The only problem was that they did not give enough economic freedom to their colonies. At almost every turn, the British tried to restrict what their colonies could do and whom they could trade with. In hindsight, I believe that the British may have been a bit more lenient on their restrictions because the constant prohibitions eventually lead to revolutionâ⬠¦ England did not directly control its colonies. Instead, they let joint-stock companies control and provide funds and foodstuffs for the colonies. Modern day corporations find their roots in these Joint-stock companies. The joint-stock companies were comprised of a group of entrepreneurs who provided the funds for all the voyages and supplies. The people funding the company usually controlled the colony as well. à à à à à The Dominion of New England was set up by English officials to unite the colonies into one defense against the Native à à à à à Americans. It was run by a man named Andros, who began to levy taxes on all the colonists without first getting input from the various assemblies from the colonies. The Dominion of New England was eventually overrun. Andros was being searched for because of the failings of this Dominion, so he took cover and tried to escape the colonies by dressing like a woman. However, his boots gave him away. à à à à à The colonists were growing more and more displeased by the economic system the British were forcing on them, and then the Molasses Act came. This Act placed high tariffs on sugar, molasses and rum imported into New England in a effort to prevent colonial trade with the French West Indies sugar islands of Martinique and Guadeloupe. British sugar merchants on the islands of Barbados, Antigua and Jamaica had complained to Parliament. The law was enacted to restrict non-British trade and to further enforce the concept that trade was to be done only on British owned ships.

Is There Too Much Sex on T.V?
Is there too much explicit sex on T. V? Over the past century, television has changed quite alot. Contents that was once seen as being inappropriate and outrageous, is now on everyday television. Recently, sex has become the main focus on our television screens. Many people think it is bad for young peopleââ¬â¢s health but others may say it is an appropriate way of advertising and attracting viewers and readers. Sexual scenes and images can lead people to a very wrong conclusion of how they should look and act. Television producers claim that what they are broadcasting is appropriate but many young people do end up watching women and men who all have perfect bodies. Body image is a major issue in the UK and according to a survey from 2008, 44% of women express negative feelings about both individual body parts and their bodies as a whole. If this is an adultââ¬â¢s view of their body, then the images in the media are affecting girls and even boys from our own generation on a much higher level, leaving many young people with very low self-esteem and lack of confidence. Reasons to support the views that there is too much explicit sex on TV is that some people feel that sex on television has become acceptable and is being broadcasted in ââ¬Ësoaps' and other programs during the day. Carolyn Teasley, a journalist said, ââ¬Å"Soap operas have bored me recently, it was becoming harder to tell who had slept with whom anyway. â⬠This quote shows that some people have became bored and lost interest in programs because they no longer care about an interesting story, or plot, only the advertisement of sex. Sex on TV can also influence children in a huge way, many teenagers have admitted to having underage sex because they have felt pressured from the television and the programmess that they watch. However, in the programmes, the teenagers do not see the dangers and consequences of sex. They only see a directors perception of an interesting scene. This can cause underage people to get sexually transmitted diseases and also underage pregnancy. Some people find sex or even the implementation of sex quite boring and not very interesting, they also don't see it as it being an important part of relationship between two people who truly love each other. Some choose to change the channel when there is a scene of a male and female undressing. Most people say that they would rather read an interesting story than see sex displayed on television. Most couples have admitted to feeling insecure when watching sex on television because the actors have perfect bodies and look a certain way and they do not. Adding to this most people, especially elderly people can feel uncomfortable watching sex scenes on television. On the other hand, some people feel that sex on television isn't as bad as some people make it out to be. For example some people feel that sex on TV can benefit children. The UK has one of the worst teenage pregnancy rates in the developed world, simply because children are not being taught enough at school about sex. A channel 4 programme called ââ¬Å"the sex education showâ⬠teaches children about sex in an appropriate manor, also the show is shown at later hours so no young children can see. Another point that can be made is that most parents complain and say there is too much sex on TV and their young child is exposed to the sexual behavior on the TV. However, sky and some freeview boxes have a parental control with a pin code to view only certain channels and it is up to the parent which programmes their child can watch, if they chose to let their child watch a programme of a sexual nature, then they have no right to comment and say it is not appropriate because the child has been given its parents discretion. Another advantage is the income that is made from these programmes and movies. Most programmes that have high ratings are of a sexual nature. Statistics show that more people watch shows with sexual content such as ââ¬ËFriends', ââ¬Ëtwo and a half men' and ââ¬Ëscrubs'. A leading journalist for the guardian said ââ¬Å"As time goes by television broadens its horizons and opens up new doors. Television draws in audiences by portraying what's on people's minds and what's going on around them. People will continue to be attracted to money and sex on television,â⬠Although many people think sex on TV is bad, the majority of people agree that is it also a good thing. To conclude, my opinion on the amount of sex on TV is acceptable. I feel that programmes of a sexual nature are shown at an appropriate time. I also feel that sex on TV does help educate young children, because young children can make up insane rumours about things involving sex and seeing the truth on TV can reasure the child of what is right and wrong. In addition I think it is the responsibility of the parent to decide what they are allowing their children to be exposed to, they shouldnt let their child watch the programme if they do not think it is suitable or appropriate for their age.

Understanding Momentum in Physics
Momentum is a derived quantity, calculated by multiplying the mass, m (a scalar quantity), times velocity, v (a vector quantity). This means that the momentum has a direction and that direction is always the same direction as the velocity of an objects motion. The variable used to represent momentum is p. The equation to calculate momentum is shown below. Equation for Momentum p mv The SI units of momentum are kilograms times meters per second, or kg*m/s. Vector Components and Momentum As a vector quantity, momentum can be broken down into component vectors. When you are looking at a situation on a three-dimensional coordinate grid with directions labeled x, y, and z. For example, you can talk about the component of momentum that goes in each of these three directions: px mvxpy mvypz mvz These component vectors can then be reconstituted together using the techniques of vector mathematics, which includes a basic understanding of trigonometry. Without going into the trig specifics, the basic vector equations are shown below: p px py pz mvx mvy mvz Conservation of Momentum One of the important properties of momentum and the reason its so important in doing physics is that it is a conserved quantity. The total momentum of a system will always stay the same, no matter what changes the system goes through (as long as new momentum-carrying objects are not introduced, that is). The reason that this is so important is that it allows physicists to make measurements of the system before and after the systems change and make conclusions about it without having to actually know every specific detail of the collision itself. Consider a classic example of two billiard balls colliding together. This type of collision is called an elastic collision. One might think that to figure out whats going to happen after the collision, a physicist will have to carefully study the specific events that take place during the collision. This actually isnt the case. Instead, you can calculate the momentum of the two balls before the collision (p1i and p2i, where the i stands for initial). The sum of these is the total momentum of the system (lets call it pT, where T stands for total) and after the collisionà ââ¬âà the total momentum will be equal to this, and vice versa. The momenta of the two balls after the collision is p1f and p1f, where the f stands for final. This results in the equation: pT p1i p2i p1f p1f If you know some of these momentum vectors, you can use those to calculate the missing values and construct the situation. In a basic example, if you know that ball 1 was at rest (p1i 0) and you measure the velocities of the balls after the collision and use that to calculate their momentum vectors, p1f and p2f, you can use these three values to determine exactly the momentum p2i must have been. You can also use this to determine the velocity of the second ball prior to the collision since p / m v. Another type of collision is called an inelastic collision, and these are characterized by the fact that kinetic energy is lost during the collision (usually in the form of heat and sound). In these collisions, however, momentum is conserved, so the total momentum after the collision equals the total momentum, just as in an elastic collision: pT p1i p2i p1f p1f When the collision results in the two objects sticking together, it is called a perfectly inelastic collision, because the maximum amount of kinetic energy has been lost. A classic example of this is firing a bullet into a block of wood. The bullet stops in the wood and the two objects that were moving now become a single object. The resulting equation is: m1v1i m2v2i (m1 m2)vf Like with the earlier collisions, this modified equation allows you to use some of these quantities to calculate the other ones. You can, therefore, shoot the block of wood, measure the velocity at which it moves when being shot, and then calculate the momentum (and therefore velocity) at which the bullet was moving prior to the collision. Momentum Physics and the Second Law of Motion Newtons Second Law of Motion tells us that the sum of all forces (well call this Fsum, though the usual notation involves the Greek letter sigma) acting on an object equals the mass times acceleration of the object. Acceleration is the rate of change of velocity. This is the derivative of velocity with respect to time, or dv/dt, in calculus terms. Using some basic calculus, we get: Fsum ma m * dv/dt d(mv)/dt dp/dt In other words, the sum of the forces acting on an object is the derivative of the momentum with respect to time. Together with the conservation laws described earlier, this provides a powerful tool for calculating the forces acting on a system. In fact, you can use the above equation to derive the conservation laws discussed earlier. In a closed system, the total forces acting on the system will be zero (Fsum 0), and that means that dPsum/dt 0. In other words, the total of all momentum within the system will not change over time, which means that the total momentum Psum must remain constant. Thats the conservation of momentum!
