Q1
The diagram below shows an unusually shaped container.
The container has four vertical tubes of different shape and size.
A person swims from a depth of 0.50 m to a depth of 1.70 m below the surface of the sea.
density of the sea water = 1030 kg/m3
gravitational field strength = 9.8 N/kg
Calculate the increase in pressure on the swimmer.
Give the unit. Use an equation from the Physics Equation Sheet.

Increase in pressure = _____________________ Unit ____________ (4)
-
Increase in depth = 1.2 m
Change in pressure,
Δp = 1.2 × 1030 × 9.8
Δp = 12112.8 PaFinal answer:
12112.8 pascals (Pa)
