Question

Archimedes’ principle is used in :

• A. ships
• B. submarines
• C. lactometers
• D. all of them

Answer 1

The correct option is D

all of them

Explanation

1. According to Archimedes' principle, ‘The upward buoyant force exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts upward at the center of the mass of the displaced fluid’.
2. Archimedes' principle is utilized in designing ships and submarines. They must have particular proportions in order for the ship to float in the water despite the high density of steel.
3. Lactometers, which are used to determine the purity of a pattern of milk, and hydrometers used for determining the density of drinks, are based totally on this precept.
4. Archimedes' principle could be very beneficial for calculating the quantity of an object that does not have a normal form.

Hence, all of them is correct. Correct option is (D).
