.... has its own assigned mass and forces as well as a force table. Weight hangers were attached to two strings tied to the center ring of the force table, where two slotted masses, one 200g and the other 249g were hung according to their specified directions. The center ring was anchored to the nail positioned at the platform’s center while the upper ring of the spring scale was attached to the free end of the third ring. After attaching the spring balance, its hook was pulled and the reading on the scale and the direction of the pull at which the two forces (hanging mass) are “balanced.� “Balance� was determined. II. Results .....

.... thought of launching the waste into outer space but it too will cost a fortune. They tried to dump barrels filled with nuclear waste into the ocean but they started leaking. As you can see, there is a great need for a nuclear waste disposal site. These sites may sound frightening, but it may be the only way for us to dispose the devastation we had longed to create. In 1986, the decision for a nuclear waste depositary proved to be "the most frightening decision of the decade." Of these sites, three were chosen to be the "most suitable" for the disposal of nuclear by-products. These three sites consisted of Hanford, Washington; Yuka Mounta .....

.... empty, it will slowly open in about a day. It may take a week to digest a housefly, and when the trap reopens, the shriveled shell of the insect is left behind. A trap may catch and digest up to three insects, after which the leaf turns black. Older leaves blacken and die regardless of how many insects are caught and the plant continually sends out new leaves during the growing season. Venus flytraps usually grow along the dampish edges of sandy, wet bogs or fens. The plant begins its growth each spring, sending out a resette of small leaves. Usually the plant flowers around April or May. Summer arrives and the plant produces its larger .....

.... a high. Inhalants are legal everyday product, which have a useful purpose. Some of these substance are paint, glues, white out, air conditioning refrigerant, felt tip makers, spray paint, air freshener, butane and even cooking spray. Inhalants can really harm the body. Almost all inhalants can cause the body to slow down. The user can suffer Sudden Sniffing Death Syndrome this means that the user can die the first time he or she uses an inhalant. Inherits can effect the other part of the body like the heart, liver, kidney, brain, bone marrow and many other organs. Inhalants can cause some of the same problems in pregnancy as alcohol does .....

.... cells of the pancreas. Epinephrine is called the “fight� or “flight� hormone. The actions of epinephrine and norepinephrine are generally similar, although they differ from each other in their effects. Norepinephrine constricts almost all blood vessels. Norepinephrine is formed by intravenous infusion to combat the fall in blood pressure associated with types of shock. Norepinephrine is formed in the body from the amino acid tyrosine, and epinephrine is formed from norepinephrine. Mineralocorticoids steroids control the overall body fluid. Mineralocorticoids are critical to regulate concentrations of minerals in extracellu .....

.... the polite arts, philosophy, theology, mathematics, and science. As the years went by, Boyle became more and more interested in medicine. His curiosity in this field led him to chemistry. At first Boyle was mainly interested in the facet of chemistry that dealt with the preparation of drugs, but soon he became genuinely interested in the subject and started to study it in great detail. His studies led him to Oxford where he joined such scientists as John Wilkins and John Wallis. Together in 1660, they founded the Royal Society of London for the Advancement of Science. From this point onwards, Boyle seriousl .....

.... The atmospheric cirulation also changes when the sea-surface temperatures in the eastern tropical Pacific rise above normal. In normal, non-El Nino conditions, the trade winds blow towards the west across the tropical Pacific. These winds pile up warm water in the west Pacific, so that the sea surface is about 1/2 meter higher at Indonesia than at Ecuador. The sea surface temperature is about 8 degrees C higher in the west, with cool termperatures off South America, dut to an upwelling of cold water from deeper levels. This cold water is nutrient-rich, supporting high levels of primary productivity, diverse marine ecosystems, and majo .....

.... shelf (Braun 55). It is in estuaries that most of the world's freshwater runoff encounters the oceans. Because fresh water is lighter, or less dense, than salt water, unless the two are mixed by the tides or winds, the fresh water remains at the surface, resulting in a salinity gradient. Tides force seawater inland as a countercurrent and produce a saltwater wedge below the freshwater surface waters (Bellamy 62). Estuaries are always in a state of change and hardly ever in a steady state. The principal energy source are tides, causing estuarine mixing, but wind, wave motions, and river runoff can also be important locally (Braun 4 .....

.... (EBV), which can be passed by coughing, sneezing or saliva transfer, where it gets it’s popular name, the “kissing disease”. Much like chicken pox, most people don’t receive a second time in their life, but it can happen. Relapses can occur, but are fairly uncommon. Although you can receive the disease very easily, is not highly contagious, according to the majority of sources. Symptoms There are many symptoms associated with infectious , but the symptoms all depend on the individual. The more common symptoms are fatigue, sore throat, swelling of the lymph nodes and malaise. There is usually a change in th .....

.... of water from the topsoil to the groundwater, due to rainfall or irrigation, can result in a dramatic rise in groundwater pressure and watertable levels. The trees of the open forests are now replaced by shallow-rooted crops and pastures which absorb far less water than the native trees. Those trees had been massive water pumps, sucking up moisture from deep underground and putting it back into the atmosphere through the evaporation from their leaves. With those pumps gone, excess rainfall accumulates underground and watertables rise to the surface, bringing ancient sediments of salt with them, often in heavy concentrations. Once ex .....
