Question

What is the force on your eardrum if its area is 1.00 cm^2, and you are swimming 3.0 m below water level?

Answer 1

Answer:

Force on eardrum

       $F=29400\times 1\times 10^{-4}=2.94N$

Explanation:

Force = Pressure x Area

Pressure = hρg

Height, h = 3 m

ρ = 1000 kg/m³

g = 9.8 m/s²

Pressure = hρg = 3 x 1000 x 9.8 = 29400 N/m²

Area = 1 cm²

Force on eardrum

       $F=29400\times 1\times 10^{-4}=2.94N$
