The statement that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces is related to:

The correct answer is Archimedes' Principle.

Key Points

• The upward buoyant force that is applied to a body submerged in a fluid, whether wholly or partially, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the centre of mass of the displaced fluid, according to Archimedes' principle.
• The Archimedes law, which was developed by Archimedes of Syracuse in Greece, provides the thrust force value.
• When an object is submerged in a liquid, whether completely or partially, the apparent weight loss is equal to the weight of the liquid that it has displaced. 

Important Points

• According to Bernoulli's principle, the total mechanical energy of a moving fluid, which includes the kinetic energy of the fluid's motion as well as the gravitational potential energy of elevation and pressure, remains constant.
• According to the Beer-Lambert law, there is a linear relationship between a solution's concentration and absorbance, making it possible to determine a solution's concentration by observing its absorbance.
• According to Blaise Pascal's law, a pressure change in a confined, incompressible fluid that happens at any place is distributed evenly throughout the fluid, causing the identical change to occur everywhere.
