| **The scuba diver plunged into the water to a depth of 25 m. With what force does the water press on the scuba diver’s chest? What is the air pressure in a scuba diver’s lungs?**

h = 25 m.

ρ = 1000 kg / m ^ 3.

g = 9.8 m / s ^ 2.

R – ?

The hydrostatic pressure of the liquid is determined by the formula: P = ρ * g * h. Where ρ is the density of the liquid, g is the acceleration of gravity, h is the height of the liquid, in our case the depth of the scuba diver’s immersion.

P = 1000 kg / m ^ 3 * 9.8 m / s ^ 2 * 25 m = 245000 Pa.

Answer: pressure in the scuba diver’s lungs is P = 245000 Pa.
