Question

3) What is Archimedes principle. Give the formula of relative density​

Answer 1

Answer:

Archimedes Principle :-

Archimedes' principle states that: The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully 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.

Relative density :-

It is the ratio of the density of a substance to the density of a standard, usually water for a liquid or solid, and air for a gas.

Relative density can be calculated directly by measuring the density of a sample and dividing it by the (known) density of the reference substance. The density of the sample is simply its mass divided by its volume.

Answer 2

ARCHIMEDES PRINCIPLE

It is a term(physical law of buoyancy) in which a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.

The volume of the fluid displaced is the equal as the volume of the original cylinder.
