Write archemedes principle

1.	Write archemedes principle
Answer» Archimedes’ PrincipleArchimedes’ Principle states that when an object is immersed fully or partially in a liquid, it experiences an upward force which is equal to the weight of liquid displaced by the object.Application of Archimedes’ PrincipleWhen the weight of displaced liquid by an object is greater than the weight of object, the object will float in liquid and when the weight of liquid will be smaller than that of the weight of the object, the object will sink in liquid.In submarines:\xa0In submarines, there is a tank which can be filled or emptied as per requirement. It is called buoyancy tank.When submarines have to go inside the water, the buoyancy tank is filled with water, so that, the weight of the submarines would become more than the weight of water displaced by it. And when submarines have to come over the surface of water, the buoyancy tank is emptied and water is replaced by air. In this condition, the weight of water displaced by submarines will become more than the weight of submarines and submarine comes over the surface of water.
