The absolute pressure acting on a horizontal submarine is

4 \times 10^5 \mathrm{~Pa}

at a certain depth of ocean. If the depth of submarine is doubled, the percentage increase in the absolute pressure acting on the submarine would be:

(1 atm

=10^5

Pascal,

g=10 \mathrm{~m} / \mathrm{s}^2,

\rho_w=10^3 \mathrm{~kg} / \mathrm{m}^3)

View answer and explanation

Correct option: B

0.75

Option B (0.75) is correct because doubling the depth increases the pressure due to water, and the percentage increase is calculated relative to the initial absolute pressure.

With the increase in temperature viscosity of a liquid - Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: When you squeeze one end of a tube to get toothpaste out from the other end, Pascal's principle is observed.

Reason R: A change in the pressure applied to an enclosed incompressible fluid is transmitted undiminished to every portion of the fluid and to the walls of its container.
