Length affects the resistance
... of the investigations of the German physicist George Simon Ohm. Alternate statements of Ohm's law are that the current I in a conductor equals the potential difference V across the conductor divided by the resistance of the conductor, or simply I = V/R, and that the potential difference ...
Resistance Of Wire Investigation (length)
... This means that if there are more atoms in the way to collide with the free electrons the resistance is increased. In a length of wire there will be a number of atoms, and in a wire twice the length, there will be twice the number of atoms. In turn this ...
Diffraction and interference of light
... wavelengths of the sodium light and each color of the hydrogen lights were accurate. This means that there was only small source of error and that is because all the instruments and measurements were accurate. We can conclude from this experiment that the property of diffraction of ...
Insulation Experiment
... test tube of hot water stays hot? Background Information I know that there are many different ways of insulating this test tube, shiny foil can be used because it's a poor emitter of radiation and it will reflect escaping heat by reflecting, because this method is used in flasks to keep hot ...
Conservation Of Momentum/Energy
... different velocities and surfaces affect the conservation. Theory: In all collisions (closed system), momentum is conserved, so long as no external forces are acting. Variables that shall be changed are the surfaces that the collision shall take place on (friction varies), the initial velocity of ...
The Big Bang Theory
... that, a theory. Though, I believe this particular theory so far is best idea we have of how the universe was formed, the Big Bang Theory is still under thorough investigational testing, and in practice this will never end. Such is the nature of ...
Notes on sound and harmonics (greek letters do not appear correctly)
... Wavelengths for various harmonics on a string) self-explanatory) Air tubes Many instruments use standing waves produced in vibrating coloumns of air to create notes. The most important point in understanding this is to realize that if an air cavity is closed, then the air ...
A Talk with Einstein about Theorizing.
... around. In this exchange, Einstein has indicated that the concern with observation in experiment is not the only basis of the formulation of the theory. But rather the theory must be firmly anchored in the wholenesss of the scientist's personal experience. Einstein's tie and unwavering ...
Pros/Cons, advantages/disadvantages of nuclear energy/fossil fuels.
... of radiation in the surrounding area. The third and final disadvantage of using nuclear energy is its thermal pollution. Thermal pollution occurs when hot effluents from a plant are placed into a lake or ocean. This causes the temperature of the water ...
Golfing In Lee County
... of distance and height. Today we still use his idea. When the player improves he goes to higher levels. Different kinds of ...
