Question

state passcal law with 2 uses ?

Answer 1

Pascal's law is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere. Applications of Pascal's law. The underlying principle of the hydraulic jack and hydraulic press. Force amplification in the braking system of most motor vehicles. Used in artesian wells, water towers, and dams.

Answer 2

Pascal's law states that pressure inside a fluid is same at the same height or altitude.  The pressure is same in all directions at any point inside the fluid.

Uses:  By measuring pressure we can know the height.  By using a wide opening and a small opening on two sides of a big fluid container, we can raise the altitudes of heavy machines or transport vehicles like trucks.

Pressure being equal at the same at the same height is used in my physics applications of dealing with fluid properties.  Fluid energy is constant in a streamlined tubular flow. This is done using Pascal's law.
