What is the force of gravity (in newtons) acting between the sun and a 4,500-kg rocket that is 0.75 au from the sun?

47.0 N

Explanation:

First of all, let's convert the distance of the rocket from the Sun from AU to metres:

The force of gravity acting between the Sun and the rocket is:

where

is the gravitational constant

is the mass of the Sun

m = 4500 kg is the mass of the rocket

r is the distance between the Sun and the rocket

Substituting into the equation,

unlike poles attract

d. air pressure decreases as altitude increases.
