A submarine dives at a constant speed pf 3 m/s. It is know that the water pressure increase at a rate of one atmospheric pressure (105 Pa) per 10 meter of depth. Find the time rate of pressure change measured by the submarine.

dP/dt = 0.3003003003

Explanation:

speed of submarine = 3m/s

rate of change of pressure with depth = (105 Pa) per 10 meter of depth

to get time taken by the submarine to cover 10m; t = 10/3 = 3.33s

time rate of change of pressure = dP/dt = 105 Pa/3.33

= 30030.03003or 0.3003003003
