Question 1

A robotic research probe is exploring a liquid methane sea on Saturn's moon Titan. The probe descends vertically from a depth of 4.20 m4.20\text{ m}4.20 m to a depth of 28.60 m28.60\text{ m}28.60 m below the surface of the sea.

Given:

  • density of liquid methane =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 pressure on the probe. State the unit.
