Four identical submarines P, Q, R and S are moved from one depth to another in water with constant density. The starting and ending depths of each submarine are shown. Which row gives the correct change in pressure between the initial depth and the final depth for each submarine?
- Aleast change in pressure: submarines P and Q; greatest change in pressure: submarines R and S
- Bleast change in pressure: submarines P and Q; greatest change in pressure: submarine R only
- Cleast change in pressure: submarine P only; greatest change in pressure: submarines R and S
- Dleast change in pressure: submarine P only; greatest change in pressure: submarine R only
