Question

Explain the application of Archimedes’ principle in submarines.

Answer 1

Explanation

1. Submarines work on the principle of Archimedes'.
2. The compressed tank and the ballast tank are the two essential components of a submarine.
3. When the ballast tank is filled with water, the submarine's density exceeds the density of the displaced water, and the submarine dives into the water.
4. When water is pumped out of the ballast tank using a compressed tank, the submarine's average density equals the density of the displaced water and hence, submarines float on water.
