A ball is thrown over the head of a person who is standing a horizontal distancedfrom the point where the ball was thrown. The initial ball’s velocity is at an angleθwith respect to the ground and has a magnitudev0. As soon as the ball is thrown, the person runs with a time-varying acceleration whose component along the x-axis isgiven byBt, whereBis a positive constant. The person catches the ball at exactlythe same height it was thrown from. Assume that the air resistance is negligible andthat the gravitational acceleration is directed downward and has magnitudeg. Findthe constantB.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the results is a decrease in air temperature with an increase of altitude.
