An alien with a mass of 71 kg is floating 670 m from his spaceship's center of mass. His ship's mass is about 500,000 kgWhat is the gravitational attraction between the alien and his ship?

5.28 x 10⁻⁹N

Explanation:

Given parameters:

Mass of alien  = 71kg

Distance  = 670m

Mass of ship  = 500000kg

Unknown:

Gravitational attraction  = ?

Solution:

The gravitational attraction can be found using the Universal gravitation law proposed by Newton;

      Fg  =  

G is the universal gravitation constant  = 6.67 x 10⁻¹¹

 d is the distance

 Fg is the gravitational attraction

  Fg  =   = 5.28 x 10⁻⁹N

the answer is a. at the equator

hi there!

your question asks at which segment does freezing occur.

since we're talking about water, the freezing point of water will be 32 degrees fahrenheit or below.

hope this ! ~
