Question 6

A research submarine is used to explore the Puerto Rico Trench, which is the deepest part of the Atlantic Ocean. The submarine descends from the surface of the ocean to the seabed at the bottom of the trench.

  • the change in pressure recorded was 84,300 kPa84,300\text{ kPa}84,300 kPa
  • mean density of seawater = 1027 kg/m3
  • gravitational field strength = 9.8 N/kg

Calculate the depth of the Puerto Rico Trench. Give your answer to 3 significant figures.
