Question

DEFINE
Buyoancy?????????????????​

Answer 1

Explanation:

Buoyancy is the upward force exerted by fluids over the surface are of contact of an object which is immersed in fluids. Buoyancy is also known as upward thrust. Why does an object sink or float over water. When an object is immersed in water, it exerts pressure over water due to its weight.

Answer 2

༄༄Answer༄༄

Buoyancy :- or upthrust, is an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid.

F_{b}=-\rho g V

F_{b} = buoyant force

\rho = fluid density

g = acceleration due to gravity

V = fluid volume
