Answer 1

pls help

Answer 2

ill have to say b and d

Answer 3

Earth and Moon. I believe.

Answer 4

Earth, Moon, and Sun! The Sun is what helps keep all the planets in alignment

Answer 5

All of the above. Read up on Newton.

Answer 6

I agree with @mastermindkakashi. I wasn't sure if it was the sun too, but go with Mastermind.

Answer 7

Then you should also read Newton's Law of Gravity:

Answer 8

Or this one, which is really clear about it...

The UNIVERSAL Gravitation Equation

But Newton's law of universal gravitation extends gravity beyond earth. Newton's law of universal gravitation is about the universality of gravity. Newton's place in the Gravity Hall of Fame is not due to his discovery of gravity, but rather due to his discovery that gravitation is universal. ALL objects attract each other with a force of gravitational attraction. Gravity is universal. This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. Newton's conclusion about the magnitude of gravitational forces is summarized symbolically as


So if you do not pick all of the above, it is wrong according to the Newton's Law of Universal Gravitation.
