Question 7

A deep-sea research submarine descends from a depth of 1.50 km to a depth of 4.20 km below the ocean surface.

Given that:

  • the average density of seawater is 1.03 × 103 kg m-3
  • the acceleration due to gravity g=9.81 m s−2g = 9.81\text{ m s}^{-2}g=9.81 m s−2

What is the increase in hydrostatic pressure experienced by the submarine?

A

2.65×107 Pa2.65 \times 10^7\text{ Pa}2.65×107 Pa

B

2.73×107 Pa2.73 \times 10^7\text{ Pa}2.73×107 Pa

C

4.24×107 Pa4.24 \times 10^7\text{ Pa}4.24×107 Pa

D

2.73×104 Pa2.73 \times 10^4\text{ Pa}2.73×104 Pa
