Figure the weight of a colume of water of area A.
force= mass*g= density*A*h*g
Pressure= force/area, then figure the height h.
If the force on the tympanic membrane (eardrum) increases by about 1.50 N above the force from atmospheric pressure, the membrane can be damaged.
When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur? The eardrum is typically 8.20 mm in diameter. Take the density of seawater to be equal 1.03*10^3.
I have no idea how these two section corrolate to eachother...and no idea where to start even thinking about the problem! help!! :(
