If the moon were twice as far from the earth as it is now, the gravitational force it
exerts on the earth would be

One-fourth of the original gravitational force.

Explanation:

The gravitational force between two objects of masses is given as:

Where,

Therefore, the gravitational force is inversely proportional to the square of the distance between the masses.

Now, if the distance is doubled, then the force has to be reduced by a factor of one by four or gravitational force will one-fourth of the original.

Let us verify it.

If , then new gravitational force is,

As seen above, new gravitational force is one-fourth of the original gravitational force between moon and Earth.

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 ! ~
