Formula for electrostatic potential energy between two charged particles change if one particles 's charge is reduced to a factor of 3?

a: increase by a factor of 9
b: decrease by a factor of 9
c: increase by a factor of 3
d: decrease by a factor of 3

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.​

that would be because of both gravity and friction. so     c

i think the answer is a and b

i wish you luck

technology is the application of the knowledge gained by science.
