Question

Find out the most suitable one regarding the pressure exerted by a liquid.

• A. height of the liquid column
• B. density of the liquid
• C. the value of acceleration due to gravity at the place
• D. all of these

Answer 1

Answer:

D. all of these

The pressure exerted by a liquid depends on all the factors mentioned: height of the liquid column, density of the liquid, and the value of acceleration due to gravity. Therefore, the most suitable answer is (D) all of these.

Explanation

The pressure (P) exerted by a liquid at a certain depth is given by the formula:

P=ρgh

Where:

• P is the pressure exerted by the liquid.

• ρ (rho) is the density of the liquid (B).

• g is the acceleration due to gravity at that location (C).

• h is the height of the liquid column (A).

This formula shows that the pressure is directly proportional to each of these three variables. If any of them increase, the pressure also increases, assuming the others remain constant. This is why a person diving deeper in the ocean feels more pressure, and why a more dense liquid (like mercury) exerts more pressure than a less dense one (like water) at the same depth.
