8. what is the force of gravity on a dog in a space suit that's running around on the moon? the dog's body has a mass of 20 kilograms. round to the nearest hundredth place. a. 196 n b. 1,176 n c. 2 n d. 32.67 n

D. around 32 N.

Given that:

Explanation:

The dog is much smaller and lighter than the moon; it behaves like a point mass. Consider the equation for the size of gravity between a spherical mass and a point mass outside that spherical mass:

,

where

The dog is at the surface of the moon. As a result, the shall be the same as the radius of the moon. Make sure all values are in SI units (kilograms and meters.) Apply the formula:

.

This value may vary slightly depending on the position of the dog on the moon.

Weight = (mass) x (acceleration of gravity)

Gravity on or near the moon's surface = 1.63 m/s^2

Dog's weight = (20 kg) x (1.63 m/s^2)

Weight = 32.6 Newtons (D)
