Answer: Pretty sure it is A.
Explanation: If you mean the molecules will get farther apart, then it is A because the molecules will be closer together in a solid.
Answer:
64.1°
Explanation:
Coefficient of friction = Horizontally resolved pushing force divided by Moving force
Coefficient of friction is 0.437
Resolving pushing force to horizontal = Moving force * Cos ∅
Therefore, 0.437 = Cos ∅
and ∅ = Arch Cos 0.437 = 64.1°
<span>The car's reference frame should be your go to. Just have the car be stationary (modifying the velocity of the rain rather than the car's). From there you should be able to get the rain's velocity by a simple equation set.</span>
