Does the Uk need new nuclear power stations
Does the UK need new Nuclear Power stations? Throughout this piece of coursework, I will be the answering the question, "does the UK need new nuclear power stations?" Once I have conducted the relevant research I hope to come up with an informed conclusion taking into account all of my sources upon whether establishing more nuclear power stations would be beneficial for the UK. I have attained information regarding nuclear power stations from numerous sources, one of which being, "The Independent" newspaper's website. The website states that Tony Blair, Prime minister of the UK, has agreed to the building of a new generation of nuclear power stations on the grounds that they would guarantee energy supplies and tackle climate change, since they do not produce gases such as carbon dioxide, which leads to global warming, unlike the traditional coal, oil and gas power stations currently in place. What is more nuclear power stations also don't emit toxic sulphur dioxide fumes, which not only worsen the symptoms of asthma sufferers but also lead to acid rain. However despite the fact that nuclear power stations, when working normally, release little or no radiation or radioactive sources into the environment, Tony Jupiter, director of "Friends of the Earth", lashes back in the same article, arguing that nuclear power stations are not a safe means of tackling climate change.

How will it end? - the universe -
How will it end? Scientists are still arguing about this, but there are three main possibilities: . If there is too much matter in the Universe, the gravitational attraction between all the masses will eventually pull all the galaxies back together into a big crunch. This is called a closed universe. This may lead to another Big Bang setting up an oscillating universe that keeps expanding and contracting. 2. If there is not enough matter in the Universe, everything will keep moving apart forever. This is called an open universe. 3. If there is just the right amount of matter in the Universe, the expansion of the Universe will slow down until it is expanding so slowly that it will appear the Universe has stopped expanding. This is called a flat universe. This evidence is found when we look at the electromagnetic radiation emitted from other galaxies. It is normally red-shifted. This means the wavelength of the electromagnetic radiation appears longer than it actually is. This is a result of an effect known as the Doppler Effect. This effect makes waves appear to have a longer wavelength if their source is moving away from you. It also means the wavelength will appear shorter if something is moving towards you. You can hear this when a police car goes past you, with its siren on. As the car approaches you, the noise is a higher pitch than when the car is moving away from
life on earth
Earth Before Life After reading the article "Earth before Life," the concepts that were addressed in the featured segment were how the atmosphere was developed and how the earth was formed. These concepts addressed the beginning of evolution and the adjustments to its surrounding. The article states "Chemical reactions and Physical processes on the early Earth created an environment that made life possible. And life, once it began, transformed the planet's chemistry. Biological and geologic histories are inseparable." Earth, a giant ball of hot gases, rocks and dust, went through a period of catastrophic and intense formation approximately 4.5 billon years ago. This was caused by particles of gases being drawn together and compressed, giving off a large amount of heat. Finally the earth cooled down enough for water vapor to condense and form liquid water. Rain fell from the sky for millions of years and covered most of the Earth with oceans and lakes. The oceans contained chemicals called nucleotides and amino acids that existed in little blobs surrounded by a membrane. These blobs are called microspheres and were not real cells but they were able to replicate themselves and reproduce. Energy from the sun and from lightning produced chemical reactions in the air that formed very complex molecules like nucleotides and amino acids. These are the building blocks of DNA

What is the solar system? Then solar system is a system comprising the sun and the astronomical bodies gravitationally bound to the Sun, the nine major planets; Mercury, Venus, earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. What are Planets? The Planets are described as censorial bodies that move around the Sun and shines by light reflected from its surface. How big are the planets in comparison with each other? The biggest of the planets is Jupiter, Pluto is the smallest. In order of size it goes Jupiter then Saturn then Neptune then Uranus, Earth then Venus then Mars Mercury and lastly Pluto. How far are the nine planets from the sun? Mercury is the closest to the sun being 57.9 (mkl millions of kilometres) Venus is 108 mkl Earth is 149.6 mkl Mars is 227.9 mkl Jupiter is 778.3 mkl Saturn is 1427 mkl and Uranus is 2870 mkl Neptune is 4497 mkl and Pluto is 5893 millions of kilometres. The Planets Mercury orbits the sun every 88 days its long period Of axial rotation 58.6 days is only two thirds of its orbital period. Mercury's surface is heavily Cratered with intervening lava pools its atmosphere Is very tenuous mainly helium and argon. Venus orbits the sun every 225 days. Its surface Is covered by dense swirling yellowish clouds of Sulphuric acid droplets and sulphur particles. The atmosphere is primarily carbon dioxide the Temperature

The Diary of the last Person First Entry: May 10th 2007 It is now three days since my life has been changed once and for all. It was three days ago that I turned 18 but did I know what was going to take place on that day. Before all this I used to go to college and I was supposed to be going to university but all these dreams have been shattered by the recent events that have taken place. I have decided to keep this diary so that one day yet to come it will be found and the human race would be able to know what happened in World War 3. I find it hard to believe that aliens launched an attack a few days ago on earth and I never knew that they really existed. It occurred so suddenly that no one knew that they were setting up an invasion on the planet earth and their intention to eliminate mankind. All around here it is all gone dead before this city used to be really busy but now you can't hear anything at all as like the place has been abandoned for years. It was judgment day, that's what it was all you could see were the national guards and the army trying to defend the people but there were too many of them they just kept on coming and coming. How can I clarify it, alien ships were landing and they were coming out from their ships the unknown creatures, butchering and murdering humans eating the flesh from the bodies. It was all horrible all I could see were bodies
The shorn Dream Planet X with Doctor Du and Larry the master.
Bhavesh Makwana 16 October 2003 English 1X1 The shorn Dream Planet X with Doctor Du and Larry the master It was another Monday morning with Shorn being moody, as school starts of at 8:45. The watch turned to 8:15 then 8:30, then 8:45 a big blast came through the door "Boom!!" as in his dream. He came through to Planet X, Welcome Master said one, people walking around in suits, one said command master any help no reply was made. Doctor Du came through with chemicals, Master let me combined an equation for the DDFR agency. Few seconds later another Boom!, one said in the background 'push to full bars' master push to 4,700 the angle moved to another angle with a furious blast. 'Fill that space, sir, there is a lot of resistance in the way to the earth, as Shorn put the fuel higher the laser beamed towards earth started to go stronger the angle started to point towards earth. Doctor Du what was in the chemical one said there was a substance that had Co2 in it that can make earth loose all there energy. On the other side Shorn was getting ready to go into the cockpit, he gave the ignition, the engine of the F-1 one growled out in its flames, blasting off in his F-1 concept flight towards earth with chemical ready to flush the earth in to his power, wonting to be in power off earth. 'What is going on set one can u hear me set one, set one!, there was no response the
Astronomical observation
Astronomical observation .Describe the observed motion of the stars during one night. At first sight stars appear not to move in the sky, they are seen static by human eyes. However recently astronomers have found that the stars are moving at fast velocities through space. The reason why they appear not to be moving is that they are so far away from us, the closest star is Proxima Centauri, which is 40 million million kilometers far away. 2.Describe the observed motion of the sun in the sky each day, and how this varies over the year, at different latitudes. From the earth the sun is seen to rise in the east, arc across the sky, and set in the west. However this is only an apparent motion, which happens because the earth spins on its axis from west to east. The sun is seen to rise higher in the sky in summer than in winter. This occurs because the earth spin is tilted in space. As the earth circles in orbit around the sun during a year, a particular place on the surface is tilted more towards the sun at some times than at others. This brings about the season. The greatest tilt occur on about June 21 and December 21 every year. On June 21 the Northern Hemisphere is tilted most towards the sun, and it is mid-summer. On December 21 the Northern Hemisphere is tilted farthest away from the sun and it is mid-winter. This days are known as the Solstices. 3. Describe the

After hearing about it, you might've wondered if it actually was real and if it was, how does it occur? Through the next pages you'll find the answers to your questions and learn how it works through physics. On a side note, you should realise that the 'green flash' is not an indication that a soul has returned to the land of living, as represented in Pirates of the Caribbean. What is a green flash? The green flash is a rare optical phenomenon that occurs shortly before sunrise or after sunset. Despite its name, there is no actual flash, rather it's more just like a spot of green above the sunset point or green rays that shoot up from the sunset/sunrise point. Types of
Compare the way in which the opening sequence of 'Star Wars' and 'Independents Day' are typical of the science fiction genre.
Media Assignment: Compare the way in which the opening sequence of 'Star Wars' and 'Independents Day' are typical of the science fiction genre. Introduction In this essay I well write about two science fiction films ' Independents Day' and 'Star Wars' and compare them to each other and to the typical science fiction genre. I will be comparing setting, costume, plot, characters, special effects, music, sound and language, and objective and style. The typical Science fiction genre involves aliens, good vs. evil, humans fighting aliens, guy gets the girl and the heroes (normally humans) save the world or defeat the evil. The Star Wars film that I will be focusing on its beginning is called Star Wars episode 1 the phantom menace. This is one of six Star Wars films. Where as Independents Day is just one film with no following films. Star Wars stars Ewan McGregar, Liam Neeson, Natalie Portman and Jake Lloyd. Independence Day stars Will Smith, Bill Pullman and Jeff Goldblum Plot Typical sci-fi plot is aliens trying to take over earth, good Vs evil, humans fight aliens, aliens steal something and the good side normally wins. Normally romance is involved. In Star Wars, two Jedi Knights, Qui-Gon Jinn and his apprentice Obi- Wan Kenobi, must rescue the young Queen Amidala and help her save her home planet, Naboo, which is under blockade by the ruthless trade federation.
AS Chemistry: Chemistry of the Stratosphere
AS Chemistry Open book paper (March 1997) There are several techniques used to investigate the chemistry of the stratosphere. The first of these is monitoring which involves analysing the air using spectroscopy. Given that ozone absorbs in the infra-red and ultra-violet regions of the spectrum, the concentration on ozone in a sample can be calculated form the strength of its absorption (figure1). This has to be carried out at different times and in different conditions to ensure any decrease is not due to natural fluctuations. Figure 1 - Ozone Distribution in the Atmosphere Once the molecules present in the stratosphere are identified, laboratory measurements can be carried out to investigate the reactivity of the molecules concerned and how radiation affects them. Special techniques such as flash photolysis have to be used to work out how fast the reactions are occurring. This technique allowed scientists to work out that the reactions breaking down and making ozone are generally occurring at the same rate and consequently there is a steady concentration of ozone. The study of meteorology involves learning about the movements of air currents which circle around the lines of latitude and help gas to mix within a layer. Meteorology allows scientists to obtain a better idea of how the reactions occur in the stratosphere as opposed to the very different conditions under
