Kathleen · Answer 1

Pressure difference between head and toes = 16872.2 Pa

Explanation:

The pressure difference between the head and toes of the man will be equal to the water pressure exerted at his toes. This can be found as follows:

Water pressure = (density of water) * (gravity) * (height of water)

Density of water = 1000 kg/m^3

Gravity = 9.81 m/s^2

Height of water = height of man = 1.72 m

Water pressure = 1000 * 9.81 * 1.72

Water pressure = 16872.2 Pa
