At what height above the ground must a body of mass 20kg be situated in order to have potential energy equal in value to the Kinetic energy possessed by another body of mass 20kg moving with a velocity of 10m/s? (Take g = 10m/s?)

Assuming the height of the first body is h and the speed of the second one is v, just equate the PE of the first with the KE of the second:

mgh = (1/2) mv^2

since they have equal mass, it cancels out and you can solve for h.

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.​

i believe the answer is electric potential.
