Question

After the big bang, atoms in gas clouds experienced a greater gravitational pull to each other than atoms in other regions of the universe. Which two statements are scientific facts that explain this phenomenon?

a. Gravitational pull on an object decreases with a decrease in its temperature.

b. As the density of an object increases, it becomes immune to gravitational force.

c. Gravitation between two objects increases when the distance between them decreases.

d. Gravity doesn’t exist between objects that are less than one light-year apart.

e. When the mass of an object increases, its gravitational pull also increases.

Answer 1

After the big bang, atoms in gas clouds experienced a greater gravitational pull to each other than atoms in other regions of the universe. The two statements that explain this phenomenon are statements C and E

C: Gravitation between two objects increases when the distance between them decreases. As gravity is inversely proportional to the square of the separation distance between the two objects, this simplifies that more separation distance will result in weaker gravitational forces and vice versa.

E: When the mass of an object increases, its gravitational pull also increases. The gravitational force increases as the size of an object increases.
