Question

how ids Archimedes Principle applied in ships , submarine, hot air balloons and hydrometer​

Answer 1

Archimedes Principle is related to the buoyancy force and density hence it can be applied in ships, submarines etc.

Explanation:

• This principle is used when ships or submarines are made. Since we know iron is greater in density than water, when a ship floats on the surface of the water the inside of it is kept hallow so that its apparent density is kept lower to make it float.

• Meanwhile, in hot air balloons, this principle is applicable in the form of buoyancy force as the weight of air in the balloon is kept less than the surrounding. This enables it to rise in air.

• Hydrometers use the principles of density in a similar way.
