Final answer:
Archimedes' principle states that the buoyant force on an object equals the weight of the fluid it displaces.
Step-by-step explanation:
Archimedes' principle states that the buoyant force on an object equals the weight of the fluid it displaces. In other words, when an object is submerged in a fluid, it experiences an upward force equal to the weight of the fluid it has displaced. This principle applies to any object in any fluid, whether it is partially or completely submerged.
