Which of the following describes the relationship between the area of a
piston and the force exerted?

a. pascal's principle
b. bernoulli's principle
c. archimedes' principle
d. flow rate equation

A. Pascal's principle

Explanation:

Pressure is equal to the force divided by the area on which it acts. According to Pascal’s principle, in a hydraulic system a pressure exerted on a piston produces an equal increase in pressure on another piston in the system. If the second piston has an area 10 times that of the first, the force on the second piston is 10 times greater, though the pressure is the same as that on the first piston. This effect is exemplified by the hydraulic press, based on Pascal’s principle, which is used in such applications as hydraulic brakes.

learn it on the intertant so you can solve

i need the answer to this too but idk it ; -;
