GEOLOGY

Detailed explanation-1: -Hence the equation P = hg represents the pressure due to the weight of any fluid having an average density at any depth h below its surface.

Detailed explanation-2: -In fact the density of water does increase with pressure.

Detailed explanation-3: -Under water, the pressure exerted on you increases with increasing depth. In this case, the pressure being exerted upon you is a result of both the weight of water above you and that of the atmosphere above you.

Detailed explanation-4: -Archimedes’ principle states that the buoyant force on an object equals the weight of the fluid it displaces. Specific gravity is the ratio of the density of an object to a fluid (usually water).

Detailed explanation-5: -According to Archimedes’ principle, weight of displaced water by an object is equal to the buoyant force or upthrust. Buoyant force is equal to the weight of the object only when it is floating.
