Question 4

A robotic exploration probe descends through a liquid methane sea on Saturn's moon Titan, from a depth of 4.50 m4.50\text{ m}4.50 m to a depth of 38.50 m38.50\text{ m}38.50 m below the surface.

Given:

  • density of liquid methane on Titan =450 kg/m3= 450\text{ kg/m}^3=450 kg/m3
  • gravitational field strength on Titan =1.35 N/kg= 1.35\text{ N/kg}=1.35 N/kg
a.

Explain why the fluid pressure on the probe increases as it descends deeper.

[2]
b.

Calculate the increase in fluid pressure on the probe. State the unit.
