the principle of Archimedes states “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it.”
Thus, when a solid is fully immersed in a liquid, it loses weight which is equal to the weight of the liquid it displaces.
Explanation:
Rockets work on the principle of Newton's Third law of motion which states that to every action there is an equal and opposite reaction.
Hydrometer, Ships, and Submarines work on the Archimedes Principle.
Archimedes Principle is also known as the physical law of buoyancy.
Archimedes Principle states that when a body is fully or partially immersed in a fluid, it experiences an upward force which is equal to the force applied by it.
