Answer 1

Correct Question : Pressure is exerted by_____

(a) Liquid

(b) Solid

(c) Gases

(d) All of these

Answer : All of these

Explanation :

A fluid is a substance that has no fixed shape and yields easily to external pressure; a gas or a liquid.

Pressure is exerted by fluids because of their weight. Static fluid pressure is exerted by the depth of the fluid, the density of the fluid and the acceleration of gravity.

Well knowingly, the solids exert pressure on the surface on which they are placed, given by

P= mg/A

Hence correct answer is option D.
