i dont get these problems-like its a foreign language to me:
1. The law of universal gravitation states that the gravitational force F (in newtons) between two objects varies jointly as their masses (with the 1 and 2 written as subscripts) m1 and m2 (in kilograms) and inversely with the square of the distance d (in meters) between the objects. The constant of variation is denoted by G and is called the universal gravitational constant.
a) write an equation for the law of universal gravitation.
b) if the mass of the earth is 5.98 x 10^24 kg, the mass of the sun is 1.99 x 10^30 kg, the mean distance between the earth and sun is 1.49 x 10^11 m, and the gravitational force between the earth and the sun is 3.53 x 10^22 N, find the universal gravitational constant.
c) what happens to the gravitational force as the masses of two objects increase and the distance between them is held constant?
d) what happens to the gravitational force as the masses of the two objects are held constant and the distance between them increases?
any help would be greatly appreciated
oh and since i dont get it-please show work so i can understand it
