.... passes along the tube. When it reaches the closed end, it is reflected. The molecules of reflected air meet the molecules of oncoming air forming a node at the closed end. When the air reaches the open end, the reflected compression wave becomes a rarefaction. It bounces back through the tube to the closed end, where it is reflected. the wave has now completed a single cycle. It has passed through the tube four times making the closed tube, one fourth the length of a sound wave. By a continuous sound frequency, standing waves are produced in the tube. This creates a pure tone. We can use this knowledge of one fourth wavelength to create our .....

.... But, at the same time it is winter in the opposite hemisphere, because it is further away, and the rays from the sun are indirect. They are indirect, because of the earth’s round shape. If you would take all ball, and shine a flashlight on it, there is no way possible to get the light to spread evenly over the entire ball. This is just like Earth and the sun. The earth’s shape makes the light amount about even, for example, at 40%S and 40%N latitude because the rays sort of fan out from the equator. While the earth is revolving around the sun, it is also rotating on it’s own axis. One full rotation equals one day or twenty- four hours. At the middle .....

.... of these mammals are domestic stock, fish, frogs, turtles, small alligators, pecarries, turtle eggs, tapir, and deer. When in captivity the jaguar can live up to 22 years. The closest relative to the jaguar is the leopard. The cubs of the jaguar are born with no father. The father leaves the mother after they are through mating.

At one month the cubs go go outside the den and follow their mother around. When six months comes and the cubs have learned how to do things the way their mother does, they begin to hu .....

.... gets within its wings or fuselage. Fuel is considered a chemical energy. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy©giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanat .....

.... in the discovery of DNA structure. Francis Crick is the one individual that may have influenced Watson the most in the discovery. Crick seemed to be a loud and out spoken man. He never was afraid to express his opinion or suggestions to others. Watson appreciated Crick for this outspoken nature, while others could not bear Crick because of this nature. Maurice Wilkins was a much calmer and quieter man that worked in London at King's College. Wilkins was the initial person that excited Watson on DNA research. Wilkins had an assistant, Rosalind Franklin (also known as Rosy). Initially, Wilkins thought that Rosy was supposed to be his assistant in researc .....

.... Acid rain makes the tree weaken and poisons it with toxic substances that are slowly released from the soil (EPA). When the trees weaken from the acid, it has a harder time fighting off adversaries such as fungi, diseases, and frost so subsequently it dies. Around the 1970s the acid rain dilemma got worse, the acid rain has put trees in danger and now they are starting to die off. The effects of acid rain on a tree is shown if it has less foliage, yellow spots and produces many cones (Baines, 22). Secondly, acid rain damages the trees through the soil by releasing metals that harm them even further (Lucas, 72). Acid rain makes .....

.... by thoughts of M16’s, grenades, and hand to hand combat. In this new era of technology that we are living in warfare has come to mean so much more. is the use of any type of information used to injure your opponent’s progress and further your own. The power of spans a broad scope of uses, from the gathering information about companies, to personal blackmail. It’s used not only by individuals against other persons, but companies and even the nation as well. As the third wave, defined by Tofflers, becomes more widely spread across the nation and world we can only expect a far larger usage of such technological tactics, being used .....
