Question

What is Archimedes principle ? Write applications of
Archimedes principle,​

Answer 1

Explanation:

Archimedes' principle states that “When a body is immersed completely or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by the body.” Applications: A hydrometer uses Archimedes' principle to determine the density of any liquid .

Some applications of Archimedes principle

• The ship can float on the water due to hollow space in a ship that can help in volume of water displaced by the ship is greater than its weight.

• Submarines are always under water because of a ballast tank that can allow the water to maintain the weight of the submarine is greater than the buoyant force.

• Fish float because of an organ called swim bladder. It can release the gas into a swim bladder or it can make it empty for rising and immersing due to change in buoyant force.

• The hot-air balloon rises and floats in mid-air because the buoyant force of the hot-air balloon is less than the surrounding air.

• Hydrometer uses archimedes principle in order to measure the density of liquids.

Answer 2

Answer:

Archimedes' principle states that “When a body is immersed completely or partially in a fluid, it experiences an upward force that is equal to the weight of the fluid displaced by the body.”

Applications:

1) It is used in designing ships and submarines.

2) It is used in making lactometers, which are used to determine the purity of milk.
