Emperor penguins are known to dive down to a depth of about 530 meter to hunt. If atmospheric pressure is 1.013 x 10^5 Pa, and the density of seawater is about 1025 kg/m^3, what is the absolute pressure a penguin experiences at that depth?

Respuesta :

Answer:

5.4 x 10⁶ Pa

Explanation:

h = depth to which penguins dive under seawater = 530 m

P₀ = Atmospheric pressure = 1.013 x 10⁔ pa

ρ = density of seawater = 1025 kg/mÂł

P = absolute pressure experienced by penguin at that depth

Absolute pressure is given as

P = P₀ + ρgh

Inserting the values

P = 1.013 x 10⁔ + (1025) (9.8) (530)

P = 5.4 x 10⁶ Pa
