Solid State Lasers Back And Forth
2,014 wordsLaser is an acronym for light amplification by stimulated emission of radiation. In the last century many types of lasers have been used for many different applications from welding to surgery to military and even many uses in every day life by harnessing the principles of light and stimulated emission. To understand how lasers work we must first understand the physics behind light waves. Light is emitted from a source and travels in straight lines and when it strikes an object is either absorbe...

2 H 2 O Carbon Monoxide
1,607 words1. State the five assumptions of the Kinetic-Molecular Theory of gases. a) Gases consist of large numbers of tiny particles. These particles, usually molecules or atoms, typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids. Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared to liquids and so...

Thus, the property being black cannot form a part of the definition of a cat. The lesson to be learnt is that definitions must be universal. They must apply to all the members of a defined set (the set of all cats in our example). Let us try to define a chair. In doing so we...

Waste Disposal Solid Waste
1,485 wordsSolid Waste Part 1 Waste disposal has always been somewhat of an issue for the human society. Our civilization has been generating various forms of waste as long as it exists, starting from the ancient times. At that time, human settlements were quite small and most of the waste consisted of easily degradable organic matter, so it didnt create much concern. However, throughout the course of human development, as our cities grew and the technological progress started producing a variety of waste ...

Life On Earth B And C
1,459 wordsCarbon dioxide is a colorless, odorless, non-toxic, and slightly acid-tasting gas. Sometimes referred to as a carbonic acid gas, the molecule consists of one atom of carbon joined to two atoms of oxygen. It occurs naturally in the atmospheres of many planets, including that of earth. Carbon dioxide is uniformly distributed over the earths surface at a concentration of about 0. 033 %, or 330 parts per million. It was called fixed air by the Scottish chemist and physician Joseph Black in the 1750 ...

Civil War Long Range
657 wordsThe artillery crews of both armies of the Civil War worked with the first guns that would eventually come to be the long-range killing machines that are used by the modern armies of today. The Civil War saw the beginnings of rifled barrels and breech loading artillery, with limited service however these new concepts were not fully developed and perfected until the years after the war. On the battlefields of the Civil War the smoothbore guns reigned supreme. There were three types of field ordina...

2,337 wordsCOMBUSTIOn &# 038; carbon Dioxide Research By Reason Hutcherson II. Combustion and carbon dioxide, what are they? When people think of combustion they probably think of simple just bursting into flames; and for carbon dioxide you probably think of what we breath out and what plants take from the air and turn to oxygen. Even though these thoughts are true there is much more to combustion and carbon dioxide. Things you might not think of about combustion are, mathematical equations, models, soluti...

Three Phases Law States
528 wordsSolids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between its atoms. The tighter the bond between its atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a definite shape and do not take the shape of their container. Liquids do not have any definite shape an...

Ovarian Cancer Oral Contraceptives
4,183 wordsOf all gynecologic malignancies, ovarian cancer continues to have the highest mortality and is the most difficult to diagnose. In the United States female population, ovarian cancer ranks fifth in absolute mortality among cancer related deaths (13, 000 /yr). In most reported cases, ovarian cancer, when first diagnosed is in stages III or IV in about 60 to 70 % of patients which further complicates treatment of the disease (Barber, 3). Early detection in ovarian cancer is hampered by the lack of ...

Solid Waste Waste Disposal
507 wordsRecycling is an ancient practice with many modern applications. It refers to the recovery and reuse of materials from spent products. In recent years recycling has become a major part of environmental policy, mainly because of the increased costs of solid- and hazardous-waste disposal, the scarcity of natural resources, and the growing concern over polluted land, water, and air. There are two types of recycling operations: internal and external. Internal recycling is the reuse in a manufacturing...
