In a certain region, the electric potential due to a charge distribution is given by the equation V( x, y,z) = 3 x 2 y 2 + yz 3 - 2 z 3 x, where x, y, and z are measured in meters and V is in volts. Calculate the magnitude of the electric field vector at the position ( x, y,z) = (1.0, 1.0, 1.0). -8.1 V/m 8.6 V/m 74 V/m 4.3 V/m 2.0 V/m

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.​
