Which of the following changes the mass of an object? a.)nothing, mass stays constant b.)changing the distance from the center of gravity c.)changing the gravitational pull of the planet d.)changing the distance from the surface of the planet

A) Nothing, mass stays constant

Explanation:

As we know that mass is the measure of the quantity of the matter and it remains the same until we break or remove the part of the mass from its system.

So here we can say that

as the gravity change the value of the gravitational force will change as we know that

so we can say that

all the effects of height or distance from the center will change the gravity due to planet so it will not affect the mass of the system

so here correct answer would be

A) Nothing, mass stays constant

the answer is 3.1 his answer is wrong mines is right

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
