13. A ball is dropped from the top of a building. After 2 seconds, its velocity is measured to be 196 m/s. Calculate the acceleration for the dropped ball.

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.

The answer is orbit around nucleus
