If a force 20N is applied to piston C. What is the pressure exerted to piston A Group of answer choices4.0 x 10^2 Pa2.0 x 10^4 Pa4.0 x 10^4 Pa2.0 x 10^2 Pa

To answer this question, we need more information such as the area of piston C and piston A. Pressure is calculated by the formula:

Pressure = Force / Area

So, if we know the force applied to piston C (which is 20N) and the area of piston C, we can calculate the pressure exerted on piston C. This pressure is the same pressure exerted on piston A (since in a hydraulic system, pressure is transmitted undiminished from one point to another).

If we know the area of piston A, we can then calculate the force exerted on piston A using the same formula rearranged:

Force = Pressure x Area

Without these area values, we cannot determine the pressure exerted on piston A.
