Which of the following represents an upside-down image?

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

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.)
