Answer:
(D) It is stronger when the objects are closer.
Step-by-step explanation:
This statement is correct. The force of gravity between two objects is directly proportional to the mass of each object and inversely proportional to the square of the distance between them, according to Newton's law of universal gravitation. As the objects get closer together, the gravitational force between them increases, and as they move farther apart, the force decreases. The shape and temperature of the objects do not significantly affect the force of gravity between them.
