A rock is projected from the edge of the top of a building with an initial velocity of 20 m/s at an angle of 30° above the horizontal. The rock strikes the ground a horizontal distance of 5 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. How tall is the building?

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.​
