Extractions: view results by Emily McPherson LASER stands for Light Amplification by the Stimulated Emission of Radiation. In 1917 Albert Einstein calculated the conditions necessary for stimulated emission; but, it was only much later, in 1960, that the first visible LASER was demonstrated by T. Maiman. However, a MASER, a similar device that emitted energy in the microwave region was the first to be developed. Basic Concepts Normally when an electron gains energy there is a random time delay before it spontaneously emits the energy as light. Sometimes this emission is said to come from a 'forbidden transition' and the time delay is much longer, though still random. This is called Spontaneous emission. If during this waiting period the electron is hit by a photon of light the electron will instantly emit its energy. This is called Stimulated emission. An unusual feature of this is that the photon emitted will be traveling in the same direction as the original photon. For this process to be sustained the rate of stimulated emission needs to be greater than that of spontaneous emission. This state is called a Population Inversion, where there are more excited electrons than unexcited electrons. However, with just two energy state involved this will never be achieved. Three or four energy levels are generally used.

Extractions: Aluminum Is the most abundant metal element in the Earths crust. Bauxite is the main source of aluminum. Aluminum is used in the United States in packaging, transportation, and building. Guinea and Australia have about one-half of the worlds reserves. Other countries with major reserves include Brazil, Jamaica, and India. More information Antimony A native element, antimony metal is extracted from stibnite and other minerals. Antimony is used as a hardening alloy for lead, especially storage batteries and cable sheaths, also used in bearing metal, type metal, solder, collapsible tubes and foil, sheet and pipes, and semiconductor technology. More information Stibnite (the main ore of Antimony) The sample in the photo contains 71.8 percent antimony and 28.2 percent sulfur. It is the most important ore for antimony. Stibnite is used for metal antifriction alloys, metal type, shot, batteries, in the manufacture of fireworks. Antimony salts are used in the rubber and textile industries, in medicine, and glassmaking.

Properties of Matter "FORMULATOR" SPEEDS UP HOMEWORK Formula: F = m x a FORCE: N MASS: kg ACCELERATION: m/s Physics Formula Calculator from http://tutor4physics.com Q. A120 lb person is being lifted aloft by a rocket which accelerates uniformly to an upward speed of 300 ft/sec in 2 sec. a) What is the upward acceleration in multiples of g? Mass of the man = 120lb Final speed of the rocket = 300 ft/sec Time = 2 sec Acceleration of the rocket can be calculated from first equation of motion v = u + at 300 = + a x 2 a = 150 ft/sec b) What is the apparent weight of the person during acceleration? Free body diagram: N - Normal reaction which is equal to the apparent weight of the man. mg - Actual weight of the man ma = N - mg N = ma + mg = m (a + g) = m (4.7g + g) = 5.7mg = 5.7 x 120 g = 684g = 684 lbf. Q. A short 10 gram string is used to pull a 50 gram toy across a frictionless horizontal surface. If a 3.0 x 10 Newton force is applied horizontally to the free end. Find the force of the string on the toy, at the other end. Mass of the string = 10 grams = 10 kg Mass of the toy = 50 gm = 5 x 10 kg Mass of toy + string = 10 + 5 x 10 = 6 x 10 kg Force applied F = 3.0 x 10 N
