Two carts are traveling at the same speed in the same direction. The first cart's speed doubles in a specified time. The second cart's speed doubles in twice that time. The magnitude of the average acceleration of the first cart is greater than the magnitude of the average acceleration of the second cart.

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.​

the answer would be a

ice to water 1 water to vapour 2 latent heat

c) up is the direction the magnetic force is acting on the charge.
