Answer 1

Answer :--

Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid. Archimedes' principle is a law of physics fundamental to fluid mechanics.

Archimedes principle has many application. It was used by archimedes to find the purity of gold. other than that some other applications are: 1. Submarine: A submarine has a large ballast tank, which is used to control its position and depth from the surface of the sea.

Answer 2

$\huge\bigstar\underline\mathfrak\red{Archimedes\:Principle}$

This principal provides information about the nature of buoyant force, its value in different fluids.

According to this force,

"When an object is immersed fully or partially in a fluid, then it experiences an upward force which is equal to the weight of fluid displaced by the object."

In other sense, it can be said,

"When an object is immersed in a liquid fully or partially, there comes a loss in its weight which is equal to the weight of liquid displaced by object."

It means that when an object is immersed then in a liquid its feels some loss in its weight. It is due to perpendicular buoyant force, which pushes it towards upward. The object displaces some liquid while immersing which is equal to loss in weight.

Applications :

★ It is used in designing ships and submarines.

★ Lactometers, which are used to determine the purity of sample of milk is based upon this principle.

★Hydrometers, which are used to determine the density of liquids are based upon this principle.
