Hydraulic brakes use pascal’s principle. the driver exerts a force of 100 n on the brake pedal. this force is increased by the simple lever and again by the hydraulic system. each of the identical slave cylinders receives the same pressure and, therefore, creates the same force output f2. the circular cross-sectional areas of the master and slave cylinders are represented by a1 and a2, respectively. how much pressure is transmitted in the hydraulic system? express your answer in pascals and in atmospheres.

Explanation:

Pascal's law states that when there is an increase in pressure at any point in a confined fluid, the pressure is equally distributed at every other point in the container.

The formulas that relate to this are given below:

P1 = P2 (since the pressures are equal throughout).

P2 is the pressure transmitted in the hydraulic system

N.B : P= Force/ Area

Therefore we have  

F1/A1 = P2

F1= the force exerted by the driver = 100N  

P2= 100/A1 N/m² or 100/A1 pa or 100/(101325× A1) atm

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

d. air pressure decreases as altitude increases.
