*help, please* In the figure above, suppose that waves from the ship are sent down and reflected back up by the sunken ship. If it takes 2 seconds for the waves to travel from their source to the sunken ship and back, what is the depth of the sunken ship? (Assume that the speed of the waves is 1,500 m/s.)

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.)
