There are two charges, one is positive and one is negative, but equal in magnitude. they are located near the origin, one slightly in the positive k direction, one slightly in the negative k direction. assume that they are very close, but with a large charge, and that the value of q*x=a, where q is the magnitude of each charge, and x is the distance they each are from the origin. for a given value of a, what is the electric field everywhere? considering the symmetries of the problem, you may want to use a cylindrical coordinate system (that is polar coordinates for the ij plane, and cartesian in the k direction)

What object a collides with object b and bounces back its final momentum is?

Lightning is an example of what phenomenon? a release of a large amount of energyan absorption of a large amount of energya natural electric circuita natural electric current

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
