Question

At a certain depth in the ocean. the absolute pressure is p. If you 90 to twice that depth (treating the water as incompressible) A) the absolute pressure will be 2p.B) the absolute pressure will be less than 2p. C) the absolute pressure will be greater than 2p. D) the gauge pressure will not change. E) Use gauge pressure will increase but will not double.

Answer 1

Answer:

correct option is B

the absolute pressure will be less than 2p

Explanation:

given data

absolute pressure = p

depth = twice

to find out

what is correct option

solution

we know here that p absolute pressure so we consider atmospheric pressure p1

so we can say at some depth h pressure will be

pressure p = p1 + ρ g h

so if depth is double

pressure will be

2p = 2p1 +2 (ρ g h )

so

2p - p1 = p1 + 2 (ρ g h )

so correct option is B

the absolute pressure will be less than 2p

Answer 2

Option B is correct. (B) The absolute pressure will be less than 2p. The pressure of having no matter inside a space, or a complete vacuum, is defined as absolute pressure.

What is absolute pressure?

The pressure of having no matter inside a space, or a complete vacuum, is defined as absolute pressure. This absolute zero serves as the reference point for pressure measurements.

The relation of the absolute and atmospheric pressure is;

$\rm p = p_1 + \rho g h$

pressure in case 2

$\rm 2p = 2p_1 +2 \rho g h \\2p - p1 = p1 + 2 \rho g h$

The absolute pressure will be less than 2p. The pressure of having no matter inside a space,

Hence option B is correct.
