How will the electrostatic force be changed if the distance between electric charges is reduced one half of the original distance? A) more than original force
B) less than original force
C) impossible to determine
D) the same as original force

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

What is the speed of an object at a given moment?

What happens when a rubber rod is rubbed with a piece of fur?
