A 15kg boulder is moved from the Earth to the Moon. Explain what happens to the mass and weight of the boulder.

The mass of the boulder remains constant, while its weight decreases with respect to the value of gravitational force on the moon.

Explanation:

The mass of the boulder = 15 kg

On the earth, its mass remains 15 kg. But its weight is;

weight = m x g

           = 15 x 9.8

           = 147 N

The boulder's weight on the earth is 147 N.

When transferred to the moon, the mass remains constant i.e 15 kg. But its weight decreases due to a change in the value of acceleration due to gravity on the moon. Thus, the boulder becomes lighter in weight.

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 ! ~

the right answer is 0.3 meters per second
