.... and the funnel can move slowly or at about 100/ft per second. Eventually the tornado becomes fragmented and dissipates causing the end of the tornado. Tornados are the cause of great destruction and devistation in the area in which they occur. For example the Tri-State Tornado of 1925 occured in the Kansas, Oklahoma, and Texas States. This tornado was one of the largest tornados recorded in history. It killed nearly 625 people. However, the tornado which strikes closest to home has occured on what Canadians have come to know as "BLACK FRIDAY". The torna .....

.... of 190 bison. The pattern or relationship between the bones and how they were found gives the archaeologist clues as to how the bison were butchered. Some bones were found with spear points in the bodies, some whole skeletons were found closer to the bottom, and some bones were scattered all over. It can be inferred from the patterning of the bison bones that they were butchered differently. Middle range theory also plays a part in the Olsen-Chubbuck site. From the visible remains of the bison, we can estimate from the skeletal remains of the bison that the .....

.... ordinary broom is a machine. It is a form of a lever. Our country or world would never be this evolved if it wasn't for machine. Almost every thing we do has a machine involved. We use machines to manufacture goods, for transportation, ect. In the W=F*d equation the trade of between force and distance is as you use a machine the force goes down and distance goes up. If there was no friction they would be equal and trade. There are six simple machines. They are a lever, pulleys, inclined plain, wheel and axle, screw, and wedge. The lever is used very ofte .....

.... availability and waste", and the other "the continuity of life support systems pertinent to survival." Thus, the environmentalists believe that nuclear energy should not be used for various reasons. First of all, the waste product, i.e. plutonium, is extremely radioactive, which may cause the people who are working or living in or around the area of storage or use, to acquire leukemia and other cancers. They also show how billions of dollars are spent yearly on safety devices for a single reactor, and this still doesn't ensure the impossibility of a .....

.... the methods scientists use in cloning. In more clear terms, cloning is the process in which DNA of a female egg is replaced with different DNA from another cell. This process is referred to as the Nuclear Transfer or Nuclear Substitution. DNA molecules are the strings of protein that hold genetic coding. In this operation, the nucleus, which is the part of the cell that contains the DNA, are carefully removed from an unfertilized female egg then replaced with the DNA from the cell of another person (Harris 4). The egg with the DNA from another person is the .....

.... galaxy. One of the most energetic explosive happenings known is a supernova. occur at the end of a stars lifetime, when its nuclear fuel is exhausted an it is no longer supported by the release of nuclear energy. If the star is particularly massive, then its core will collapse and in so doing will release a huge amount of energy. This will cause a blast waver that ejects the stars envelope into interstellar space. The result of the collapse may be, in some cases, a rapidly rotating neutron start that can be observed many years later as a radio pulsar. As a re .....

.... of the high tech instruments became useless. They realized that they could not even make it to Winnipeg. Their only chance was an abandoned to a abandoned Air Force airstrip. Unfortunately, the airstrip had been converted to a race track, complete with race cars, fences, and spectators. The 767 crash landed, and, fortunately, no one was killed. Their were many contributing factors that made this plane run out of fuel. First of all, the computerized fuel gauge was not working, and a maintenance worker said , incorrectly, that the plane was still certifie .....

.... that there is no bare metal, chips or cracks on the vehicle, which is impractical. Another problem is that it is almost impossible to hold a charge (potential difference) on a sharp thin edge of metal, and so this technology is not really suited for vehicles, which are made up of many irregular shapes. Because of this, it is also ineffective on existing rust and the areas surrounding it, as rust always causes sharp edges and damaged paintwork. Electronic rust prevention is another method used to prevent rust using one of two technologies; either Impressed Curren .....
