Suppose a new moon was discovered orbiting the Earth. This new moon is 2.45 times further than our original moon and has 3.0 times the mass as well.
3. Find the gravitational force that exist between the Earth and the new moon.
4. What is the orbital velocity of the new moon?
5. How long would it take the new moon to orbit the Earth once in days?

it doesn't. it was imagined up in the middle ages.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
