Answer 1

Answer:

Archimedes' principle is used to design ships and submarines.

Explanation:

Archimedes' principle states how to calculate the buoyancy experienced by an object which is partially or completely immersed in water. According to this principle, the buoyancy experienced by an object is equal to the weight of the water displaced by it. It also explains that the volume of the fluid displaces will be equal to the volume of the object immersed in the fluid. Ships and submarines are designed using this principle.

For a ship to float on water, it should be designed in such a way as to balance these volume conditions. Otherwise, the ship will sink. Submarines also use this principle to maintain their water level inside the water. The volume of the ship is made unbalanced for the ship to submerge, by allowing the water to enter inside or outside the vessel.
