According to the diagram, the block should be moving in which direction? a. there is no way to tell which way the block should move. b. the block should move to the right. c. the block should not move at all. d. the block should move to the left.

D. The block should move to the left.

Since the forces are in opposite directions the difference of these forces determines the magnitude and direction of the block.  Therefore,

20 N left - 10 N right = 10 N left

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.​

unbalanced force
