wire move very slowly through wires. A typical speed for an electron in a battery circuit is 5.0x10 to the -4th meters per second. How long does it take an electron moving at that speed to travel a wire 1.0 centimeter‚ or 1.0x10 to the -2nd? Part B: Electrons move quickly through wires‚ but electric energy does. It moves at almost the speed of light‚ 3.0x10 to the 8th meters per second. How long would it take to travel 1.0 centimeters at the speed of light? Part C: Electrons in an ordinary flashlight

1905‚ Albert Einstein published the theory of special relativity‚ which explains how to interpret motion between different inertial frames of reference — that is‚ places that are moving at constant speeds relative to each other. Einstein explained that when two objects are moving at a constant speed as the relative motion between the two objects‚ instead of appealing to the aether as an absolute frame of reference that defined what was going on. If you and your friend‚ say AA‚ are moving in different

HORIZONTAL ASYMPTOTES We define the line y = L as a horizontal asymptote of the graph of f(x)‚ iff f(x) approaches L as x approaches infinity (or negative infinity). For the function the line is the horizontal asymptote of the graph of . The following limit shows why this is true: and When x approaches infinity‚ approaches the line‚ and when x approaches negative infinity‚ also approaches the line . A quick way to determine the

The theory of relativity came from Einstein’s search for a general law of nature that would explain a problem that had occurred to him when he was sixteen. "No matter what speed the observer is moving at‚ he must always observe the same velocity of light‚ also that if an observer at rest and an observer moving at constant speed carry out the same kind of experiment‚ they must get the same result"(Albert Einstein Biography). By using the theory‚ he changed the way how people only believed in Newton’s

Special Theory of Relativity means a physical theory of relativity based on the assumption that the speed of light in a vacuum is a constant and the assumption that the laws of physics are invariant in all inertial systems. Albert Einstein created many different experiments one being where Mrs. Einstein is standing in a field and Mr. Einstein is standing
