If the masses of objects increase and their distance from each other remains the same, then the force of gravity between the two

Answer:
The answer is B. Increases.
Explanation:
The force of gravity expressed in a formula is equal to
In which:
(F) equals the force of attraction
(G) is equal to the universal gravitation constant
(M1) represents the mass of body number 1
(M2) represents the mass of body number 2
(D) represents the distance between the two bodies
So as the masses are in the numerator, if they are increased the fraction in the same way will increase. For this reason if the masses of these bodies increases the force of gravity will also increase.

Answer:
Explanation:
Assume that the distance travelled initially is d.
In order to stop the block you need some external force which is friction.
If we use the law of energy conservation:
a)
Looking at the formula you can see that the mass doesn't affect the distance travelled, as lng as the initial velocity is constant (Which indicates that the force must be higher to push the block to the same speed) therefore the distance is the same.
b) If the velocity is doubled, then the distance travelled is multiplied by 4, because the distance deppends on the square of the velocity.
