Question # 1
In automobile braking system, what are the retarders?
Retarder is used to augment or replace some of the functions of primary friction-based braking systems, usually on heavy vehicles.
Question # 2
What type of substance does Pascal's principle deal with?
Hydraulic systems use the Pascal's principle.
Question # 3
In a hydraulic system, a piston with a cross-sectional area of 21 square centimeters pushes on an incompressible liquid with a force of 38 Newton's. The far end of the hydraulic pipe connects to a second piston with a cross-sectional surface area of 100 square centimeters. What is the force on the second piston?
Question # 4
What will happen to the water level in the capillary tube when air is blown in the horizontal pipe, as shown in image?
When air is blown in the horizontal pipe, pressure in the pipe decreases.
Question # 5
We have two liquids A and B which exert same amount of pressure. What would be the height of column of liquid A if the density of liquid A is twice as that of liquid B and height of column of liquid B is 10 cm?
As both liquids exert same amount of pressure, so we can find the height of column of liquid A by using P A = P B , where P A and P B are pressures exerted by liquids A and B.
