Where do people get their energy to turn a wheel??

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.)

If jerome is swinging on a rope and transferring energy from gravitational potential energy to kinetic energy, is being done.

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.
