Amoving particle encounters an external electric field that decreases its kinetic energy from 9970 ev to 6340 ev as the particle moves from position a to position b the electric potential at a is 55.0 v and that at b is 19.0 v determine the charge of the particle include the algebraic sign or with your answer

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.​
