Saturn

... for Saturn's equatorial bulge and oblate shape. The equatorial-polar-diameter ratio is 1.12 to 1. Saturn's mass is 5.686 X 10 to the power of 26 kg , or 95.147 times the Earth's. Thus the average density is only 0.69 g/cu cm , which is much less than water, indicating a very deep atmosphere and a very small core. Saturn is one of the giant outer planets, which are characterized by their large size, low density, and corresponding extensive atmospheres. Current models of the interior indicate that below the relatively thin opaque cloud lay ...

Asteroids

... single McDonald's franchise. Total disaster would occur no matter where the asteroid hit. Land, sea it doesn't matter. Ocean impact would create a number of things. First, a Tsunami(tidal wave) would be created on impact. The wave would be hundreds for feet high traveling hundreds of miles per hour. It would start to slow down crashing ashore through all coastal city. Then, finally wash up hundreds for miles inland. " The mid-Atlantic Ocean impact ranging from 400 meters to 5 kilometers in diameter. This would generate a tsunami that would swe ...

Lasers And Their Applications

... that allows lasers to work. Constructive interference is what amplifies light. Since light is a wave it has a frequency calculated by the equation: = c/f where f is the frequency c is the speed of light which is equal to 3.00 x 108 m/s and is the wave length of light. Also waves have crests, the high points of waves, and troughs, the low points. Constructive interference occurs when two waves of the same frequency meet at a crest or trough therefore combining to form a wave that has an amplitude equal to the sum of the individual amp ...

Human Origins

... much scientific evidence and studies, there is now physical proof that human beings may have evolved from ape-like creatures. Even with this, there are still disputes in the paleoanthropological field of whether or not this is true. Still, many choose to believe their religious creation stories where a God created humans. Whether it is Johanson's idea on human evolution or Leakey's or even the Roman Catholic's creation story, all are an individual own interpretation and neither wrong nor right. A paleanthropologist by the name of Donald Joha ...

Air Pollution

... now? Factory and business owners have the ability to prevent . is the presence in the atmosphere of harmful gases, liquids, or solids. , known as smoke pollution for many years, resulted from coal combustion (Hodges 526). Smog has been a problem in coal-burning areas for several centuries. Smog finally decreased when coal combustion was replaced by oil and gas combustion. is caused by a number of different types of pollutants. The first type, particulate matter, consists of solid and liquid aerosols suspended in the atmosphere. These ar ...

The Acid Rain Effects On Living Things

... the major cause acid rain is air pollution from the burning of fossil fuels. The smoke and fumes from burning these fossil fuels rise into the atmosphere and combine with moisture in the air to form acid rain. The main chemicals in air pollution that create acid rain are sulfur dioxide and nitrogen oxides. Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. This forms a mild solution of sulfuric acid and nitric acid. These chemical reactions that change air pollut ...

Acid Rain

... problem was first brought to light about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, or even decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers and lak ...

Hydrogen: The Fuel Of The Future

... universe (in other forms i.e. water on earth, and its form in space is a gas). Hydrogen can do just about everything conventional fuels can do but better. Hydrogen can be "packaged" in several ways, as a fuel gas in a H2/02 powered engine or the newly devised solid state pellet of hydrogen isotopes that contains about the equivalent of 5000 cubic feet of hydrogen and is broken down and releases gas into the second chamber where it goes to the engine for use. There are many ways to get pure hydrogen out of many compounds using methods such as ...

Coral

... and they make a ring-shaped reef that close a circular lagoon. reefs are the largest biological structures on the planet, with the largest being the Great Barrier Reef covering over 2000 kilometers along the east coast of Australia. The reef is said to be 500,000 to 2,500,000 years old and is said to be visible from the moon. There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse by coal miners, fisheries, and ...

Kevlar

... flexible-chain molecules, such as nylon or polyester, this could only be done by mechanically drawn in after spinning. This required chain disentanglement and orientation in the solid phase of it. Therefore the strength and modulus levels were far lower than theoretically possible values. In 1965, scientists at Du Pont discovered a new method of producing an almost perfect polymer chain extension. The polymer poly-p-benzamide was found to form liquid crystalline solutions due to the repetitiveness of its molecular backbone. The key for ...

Aquired Dyslexia

... the task of reading the written word. It can not be determined by introspection or studying the human brain in action as this is not possible. The way Psychologists and Neuroscientists have developed to determine hoe humans read is to observe people who have suffered some form of brain damage and have thereby incurred some form of reading disability. This disability is known as acquired dyslexia. From the study of such patients several variations of a basic model have been developed to highlight the way in which the written word is processed ...
