Two 65 kg astronauts leave earth in a spacecraft, sitting 1.6 m apart. How far are they from the center of the earth when the gravitational force between them is as strong as the gravitational force of the earth on one of the astronauts?

You are seated 1.5 m away from your best friend. One of you has a mass of 60 kg and the other has a mass of 70 kg. a) What is the magnitude of the gravitational force that each one of you exerts on the other? B) What is the direction of this force?

The earth is 150 × 10^9 m from the Sun. Earth and Sun masses are 5.97 × 10)^24 ?? and 1.99 × 10^30 ??, respectively. (a) Find the gravitational attraction between the Earth and the Sun. (b) Find the orbital period of the Earth around the Sun based on these numbers.

Two books are on a shelf 1.3 m from one another. Book A has a mass of 2.2 kg. Book B hasa mass of 1.7 kg. An absentminded student picks up book A to see if it is useful for his re-search paper. He decides not to use the book and sets it on a shelf 1.8 m from book B.What effect does this have on the gravitational force between the books?AThe gravitational force remains the same because the masses of the books remainconstant.BThe gravitational force decreases because the distance between the books increases.The gravitational force increases because the distance between the books increases.DThe gravitational force remains the same because distance does not affect gravity for small objects

With what gravitational force does the sun attract the earth? The mass of the sun is 1.99x10 kg 24 The mass of the earth is 5.97x10 kg The distance between sun and earth is 150.3x10 m Answer:

Two asteroids are separated by a distance in space. One asteroid collides with a cluster of smaller ones which increases its mass by 2½ times. In the process the distance between the two asteroids decreases by ⅔. What is the change in the gravitational force between them? Express you answer as a factor of the original gravitational force.

In the figure, three 7.82 kg spheres are located at distances d₁ = 0.226 m, and d₂ = 0.204 m. What are the (a) magnitude and (b) direction (relative to the positive direction of the x axis) of the net gravitational force on sphere B due to spheres A and C? (a) Number (b) Number IN M. d₁ A B ∙d₂ Units Units N ° (degrees)

1) What is the speed of the satellite in m/s?

A space probe is launched from Earth headed for deep space. At a distance of 10,000 km from Earth's center, the gravitational force  on it is 900 N. What is the magnitude of the force when the probe is 30,000 km from Earth's center?
