This refers to the previous question in which a wave propagates in air and is transmitted through a piece of paper. Does increasing the frequency increase the amplitude of a sound wave transmitted through the piece of paper

A14 kg rock starting from rest free falls through a distance of 5.0 m with no air resistance. find the momentum change of the rock caused by its fall and the resulting change in the magnitude of earths velocity. earth mass is 6.0 * 10^24 kg. show your work assuming the rock earth system is closed.
