Question

)a) State the Pascal’s law
b) Name three devices that works based on this principle

Answer 1

Answer:

a) Pascal's law states that if the pressure is applied to uniform fluids that are confined,the fluids will then transmit the same pressure in all directions at the same rate.

b) Pascal's principle applies to all fluids, whether gases or liquids. A typical application of Pascal's principle for gases and liquids is the automobile lift seen in many service stations (the hydraulic jack).

Answer 2

a, Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container. ... Applied to a more complex system below, such as a hydraulic car lift, Pascal's law allows forces to be multiplied.

b, ammeter

An electric generator (are called dynamo) is a machine which generates electricity by using the principle of electromagnetic induction.
