Answer: The tidal forces exerted by the moon are directly associated with the earth's rotation. Due to the strong gravitational pull of the moon, the tidal bulging appears on both the sides on earth and these are region of high tide, and there is gradual rise and fall of sea level.
Because of these tidal effect, the earth is able to rotate only once in each of the orbital period.

Given:
The mass of the truck is m1 = 3162 kg
The speed of the truck is v1i = 12 m/s in East
The mass of the parked car is m2 = 510 kg
The speed of car is v2i = 0 m/s
The speed of car after collision is v2f = 24 m/s in East
To find the speed of the truck after collision.
Explanation:
The final velocity of the truck will be
Thus, the speed of the truck after collision is 8.129 m/s
the answer is 5 m up AKA "B"
Correct answer: B
The force of gravity acting on the object on the moon can be found by multiplying its mass by the acceleration due to gravity on the moon. The acceleration due to gravity on the moon is a constant and is approximately 1.63m/s².
120kg×1.63m/s²=195.6kg.m/s²
kg.m/s²=N
<span>The force of gravity acting on the object on the moon would be of approximately 196N.</span>
