- 471: Emotional and Rational Appeals
- ... at the University of California at Santa Barbara, 184 students received partial course credit in return for their participation. Subjects in the experiment were assigned to the cells of a 2(positive or neutral mood) x 2(emotional or rational message type) x 2(strong or weak argument quality). Subjects were in groups of two to six. After this step was established, eight messages in approximately equal length were developed. Each message contained six arguments that were either ...
- 472: The Superstring Theory
- ... theories, each requiring ten dimensions (nine space and one time), and that each of them has a consistent description in terms of maintaining "intelligibility." The five theories, are type I, type IIA, type IIB, E8 X E8 heterotic (HE, for short), and SO [32] heterotic (HO, for short). The type II theories have two supersymmetries in the ten-dimensional sense, while the other three have just one. The type I theory ... is they are the developers of the HE string theory. This theory has latent properties that are surpassing when compared to the original (superstring theory that is). This was done by using the E(8) x E(8) string symmetry, which happened to be compatible with all the earlier grand unification theories (meanings, it was consistent with all known experiments). The only "problem" is that under this symmetry, thousands of particles ...
- 473: Barium
- ... in automobile ignition systems. Barium sulfate (BaSO4) is used as a filler for rubber products, in paint, and in linoleum. Barium nitrate is used in fireworks. A form of barium sulfate, which is opaque to X rays, is used for the X-ray examination of the gastrointestinal tract. Naturally occurring barium is a mixture of seven stable isotopes. Twenty two other radioactive isotopes are known to exist. Barium is an ore found in the ground. It is ...
- 474: Newton's Method: A Computer Project
- Newton's Method: A Computer Project Newton's Method is used to find the root of an equation provided that the function f[x] is equal to zero. Newton Method is an equation created before the days of calculators and was used to find approximate roots to numbers. The roots of the function are where the function crosses the x axis. The basic principle behind Newton's Method is that the root can be found by subtracting the function divided by its derivative from the initial guess of the root. Newtons Method worked well because ...
- 475: Rates of Reaction
- ... the amount of moles that we have to use the formula: Moles = mass of sample 100 =0.004 moles. volume with 1 mole 24,000 To get the maximum mass we can use: Mass = moles x RAM. = 0.004 x 24 = 0.0096g So, this is the maximum amount of magnesium we can use. To the nearest 0.01 of a gram = 0.01. This is the maximum amount of magnesium we can use. Because ...
- 476: Freezing Point of Naphthalene
- ... 30 70.3oC V. Graph (See following pages) VI. Calculations Using 80.1 oC as the theoretical value for the freezing point of naphthalene, we can now determine percent error. Percent Error = ((Theoretical - Experimental) / Theoretical) x 100 Percent Error = ((80.1 oC - 79.0 oC) / 80.1oC) x 100 Percent Error = 1.4% VII. Conclusions In this lab, we heated the known substance naphthalene in a test tube to approximately 100oC and observed its temperature while it cooled to approximately 70oC. Over a ...
- 477: The Discovery Of The Electron
- ... Thomson in the form of cathode rays, and was the first elementary particle to be identified. The electron is the lightest known particle which possesses an electric charge. Its rest mass is Me 9.1 x 10 -28 g, about 1/1836 of the mass of the proton or neutron. The charge of the electron is -e = -4.8 x 10^-10 esu and in many other decay processes. The electron itself is completely stable. Electrons contribute the bulk to ordinary matter; the volume of an atom is nearly all occupied by the cloud of ...
- 478: The Study of Akali Metal Contamination in Road Side Soil
- ... of the fact that equation 1 is a quadriatic equation of the general form: y=ax2+bx+c, with yΉ0, where a, b, and c are constants. At any point in the domain of x, y takes on a constant value and the following equation can be written: 0= ax2+bx+(c-y). Let (=(c-y).The difference of two constants is certainly a constant, thus, 0= ax2+bx+(. The quadriatic formula can be written as x= . Only the solution obtained from adding the discriminant was used in subsequent calculations. -Ca Emission: -Ca Absorbtion: eq(2): I=(0.243)C+(0.570) eq(3): A=(0.459)C+(0.100) eq(2A ...
- 479: Crystals: Does Surface Tension Affect the Process of Crystallization?
- ... on the growth of crystals; it would probably reduce the speed of the growth of the crystals or would cease the growth if the surface tension is too great. MATERIALS 5 clear plastic cups 5 x 100 ml beakers 1 cup of water 1 cup of alcohol (isopropyl-rubbing alcohol) 1 cup of bleach 1 cup of corn oil 1 cup of dishwashing liquid (brand name "Dawn") 5 x 1/4 cup of table salt 1 small portable stove 1 thermometer 1 stiring rod 5 straws 5 strings (15 cm in length) 5 staples scale which measures in milligrams PROCEDURE 1) label cup for ...
- 480: The Search for Black Holes: Both As A Concept And An Understanding
- ... several approaches to this question. Obviously, as realized from a previous paragraph, by seeing, it isnt necessarily meant to be a visual representation. So were left with two approaches. The first deals with X-ray detection. In this precision measuring system, scientists would look for areas that would create enormous shifts in energy levels. Such shifts would result from gases that are sucked into the black hole. The enormous ... circumference. The only problem is that these ripples are so minute that detecting them would require instrumentation way beyond our present capabilities. Because theyre unaffected by matter, they carry a pure signal, not like X-rays which are diffused and distorted. In simulations the black hole creates a unique frequency known as it natural mode of vibrations. This fingerprint will undoubtedly point to a black hole, if its ever ...
