an object is 40M below the surface of sea water of density 1020 kg/m3 calculate the pressure difference

P = 400248 [Pa]

Explanation:

We can calculate the hydrostatic pressure exerted by a column of liquid by means of the following equation.

where:

Ro = density = 1020 [kg/m³]

g = gravity acceleration = 9.81 [m/s²]

h = depth = 40 [m]

Therefore:

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.
