Determination of buoyancy.

The buoyancy or lifting force appears when we take any body and immerse (immerse) it in a bath with some kind of liquid, or put it in gas. As a result of such immersion, force immediately begins to act on the body. This force tends to push the body out of the submerged environment. And to calculate this buoyancy force acting on a body, we need to know the volume of the body. Based on the volume of a body, we can determine the weight of a liquid or gas in the volume of this body. This is the Archimedes law, according to which we can calculate the buoyancy force. It is the product of the density of a liquid or gas, the acceleration of gravity and the volume of a body immersed in a liquid or gas.
