The moon is 3x10^5 km away from Nepal and the mass of the moon is 7x10^22 kg. Calculate the force with which the Moon pulls every kilogram of water in our rivers.

Approximately .

Explanation:

Let denote the gravitational constant. (.)

Let and denote the mass of two objects separated by .

By Newton's Law of Universal Gravitation, the gravitational attraction between these two objects would measure:

.

In this question: is the mass of the moon, while is the mass of the water. The two are apart from one another.

Important: convert the unit of to standard units (meters, not kilometers) to reflect the unit of the gravitational constant .

.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.
