People can snorkel down to a depth of roughly one metre. This means that the additional pressure on the air in their lungs is roughly: A)9 800 N. B)9 800 Pa. C)9 800 ATM. D)19 600 N. E)19 600 N/m².

Question

Quizplus · Accepted Answer

The additional pressure on the air in their lungs is equal to the pressure of the water at that depth, which can be calculated using the formula P = ρgh, where ρ is the density of water, g is the acceleration due to gravity, and h is the depth. Assuming a density of 1000 kg/m^3 for water, and g = 9.8 m/s^2, the pressure at a depth of one metre is approximately 9,800 Pa.
