Question

what are fluids? why is archimedes? principle applicable only for fluids ? give the application of archimedes principle

Answer 1

Fluids are those substances which can flow e.g. gas&liquids. 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. Yes,it is only applicable for fluids. Applications are submarine,hydrometer,hot air balloonsconditioning,ship,fishes etc.

Answer 2

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.
