What does the zeroth law of thermodynamics allow us to define?

Explanation:

Zeroth law of thermodynamics is known as the law of thermal equilibrium.

This law states that the two systems that are in thermal equilibrium with the third system then the two systems will be in equilibrium with each other.

According to this law, if two systems A and B individually are in thermal equilibrium with third system C, then systems A and B will also be in thermal equilibrium with each other.

Thermal equilibrium is a condition where two systems in equilibrium exchange no heat energy. There is no change in temperature.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
