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
