Physics!!!! several questions true or false?

Question

1. the speed of a satellite orbiting earth depends only on the mass of earth and (the mass of the satellite)

2. the equations of motion are (different) for objects in orbit around earth and for planets orbiting the sun

3. orbital speed and period are (independent) of the mass of the satellite

4. if the radius of earth were changed but the mass remained the same, acceleration due to (gravity would not change)

5. as you move further away from earth's center, acceleration due to gravity changes according to (a direct) relationship

Answer 1

1. true because the satellite's speed and inertia is based on its mass
2. true because the planets orbit the sun in an elliptical pattern whereas the moon orbits the sun in a circular orbit
3. dependent
4. true because gravit is based on mass of a planet not the radius
5. true, the further you go the less gravity you will feel or have

Answer 2

1) False. It does not depend on the mass of the satellite. The speed also depends on the radius of the orbit.

2) False. All laws of physics are the same everywhere in all reference frames.

3) This is true.

4) Not true. g = GM/R^2 where R is the radius of the earth, g is acceleration due to gravity, M is the mass of the earth, and G is the gravitational constant.

5) False. It changes according to an inverse square relationship.

Answer 3

I'm now not certain, however... The first 3 are actual. The fourth one is meh. The fuel pedal speeds up your automobile, which alterations the pace, so I bet it is actual. 5th and 6th are actual. I believe they are all actual, so I'm now not certain. It's turns out somewhat unusual that they might all be actual, however I believe they're.
