C. When the center of Earth is 2 x 10 meters from the center of Mars, the force of gravity between the two planets is about 64.32 * 1014 newtons. The mass of Earth is about
6 x 1024 kilograms, and the mass of Mars is about 6.4 * 1023 kilograms. Using these
values, estimate the gravitational constant.

The height of a birch tree, f(x), in inches, after x months is shown in the graph below. how much does the birch tree grow per month, and what will be the height of the birch tree after 10 months? a. the birch tree grows 1 inch per month. the height of the birch tree will be 16 inches after 10 months. b. the birch tree grows 2 inches per month. the height of the birch tree will be 26 inches after 10 months. c. the birch tree grows 3 inches per month. the height of the birch tree will be 36 inches after 10 months. d. the birch tree grows 2 inches per month. the height of the birch tree will be 24 inches after 10 months.
