If two carts collide, what type of collision will conserve both momentum and kinetic energy?
a. head on c. none
b. inelastic d. elastic
39. the impulse experienced by a body is equivalent to the body’s change in
a. velocity c. momentum
b. kinetic energy d. force

For the first one I believe it would be D. And for 39 it would be c

we need some answer choices, or something like that

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.​
