The earth rotates through one complete revolution every 1,440 minutes. Since the axis of rotation is perpendicular to the equator, you can think of a person standing on the equator as standing on the edge of a disc that is rotating through one complete revolution every 1440 minutes. Find the angular velocity of a person standing on the equator.

The angular velocity of a person standing on the equator is approximately radians per second.

Explanation:

The Earth rotates at constant speed. From Rotational Physics, the angular velocity (), measured in radians per second, is defined by the following formula:

(1)

Where is the period of rotation of the Earth, measured in seconds.

If we know that , then the angular velocity of a person standing on the equator is:

The angular velocity of a person standing on the equator is approximately radians per second.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
