Concept:

Pascal’s Law:

It was given by Blaise pascal
It is also known as the principle of transmission of fluid pressure
It states that the pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
Alternate definition:- The pressure applied to any part of the enclosed liquid will be transmitted equally in all directions through the liquid.

Applications:

The underlying principle of hydraulic jack and hydraulic press.
Force amplification in the braking system of most motor vehicles.
Used in artesian wells, water towers, and dams.

Calculation:

Given:

Diameter of plunger, d = 3 cm, Diameter of ram, D = 20 cm, Force required at the plunger = ?, Weight = 30 kN

According to pascals law,

Pressure applied at ram = Pressure exerted on the plunger

Here, F₂ = force required on the plunger

Child psychology is certainly not a strong point with most Indian schools, why else would it inflict a double trauma on a student faring badly in the pre-boards by banning her from taking the exams.Often with fatal results as evidenced by reports of student suicides in the run-up to the board. Now the Central-Board of Secondary Education (CBSE) has stepped in and put the brakes on the CBSE. This is good news for parents and students, many of whom have had to live with the threat performance-linked department.While the schools logic is that in order to attract talented students, need to maintain their performance records at high levels. The assumption that a student faring poorly in the pre boards will replicate this at the boards is faulty.Chances are that the student will be spurred to work doubly hard, On the other hand, the threat of department will almost certainly impact adversely her performance. Of course, linking pre-boards to the boards is only one of the problems with our school system.Choose the word which is similar in meaning as the word Replicate as used in the passage.
