The cue ball collides with a pool ball. however, the pool ball doesn’t have much mechanical energy as the cue ball. how is energy conserved if the pool ball has less energy than the cue ball?

Some of the energy in the pool ball was lost through friction as they collide and then roll across the table

Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. the winds blow from west to east in jet streams but the flow often shifts to the north and south. jet streams follow the boundaries between hot and cold air. the earth's rotation is responsible for the jet stream as well.

Answer sample (c); // would be best because the percentage of the energy in an incident wave that remains in a reflected wave from this material is the smallest;
