Express Pascal’s law, and give a real-world example of it.
Solutiona)What is Pascal's lawAccording to Pascal's lawThe external static pressure applied on a confined liquid is distributed or transmitted evenlythroughout the liquid in all directions.The static pressure acts at right angles to any surface in contact with the fluid. Pascal also foundthat the pressure at a point for a static fluid would be the same across all planes passing throughthat point in that fluid. Pascal’s law is also known as Pascal’s principle.Pascal's law formulaF is the force appliedP is the pressure transmittedA is the cross sectional areaPascal's law used in our daily lives such as hydraulic brakes and lifts.b)Real world example of Pascal's law\nA common application of this is a hydraulic lift used to raise a car off the ground so it can berepaired at a garage. A small force applied to a small-area piston is transformed into a largeforce at a large-area piston. If a car sits on top of the large piston, it can be lifted byapplying a relatively small force on the smaller piston, the ratio of the forces being equal to theratio of the areas of the pistons.
