Which explains the operation of a hydraulic lift system? pascal’s principle bernoulli’s principle newton’s principle archimedes’ principle

Pascal's law explains the operation of a hydraulic lift system.

Option A

Explanation:

Pascal's law is related to the fact that when there is an increase in pressure at a particular point in a liquid, then there is an increase in pressure at every other point present below.

This concept is applied in hydraulic lift system and so it works on the principle of pascal's law. Benoulli's principle is used in airplanes and in nozzles. Archimedes principle is related to buoyant force.
