Question

If you dive underwater, you notice an uncomfortable pressure on your eardrums due to the increased pressure. The human eardrum has an area of about 70 mm217 * 10-5 m22, and it can sustain a force of about 7 N without rupturing. If your body had no means of balancing the extra pressure (which, in reality, it does), what would be the maximum depth you could dive without rupturing your eardrum

Answer 1

Answer:

$h=10m$

Explanation:

From the question we are told that:

Area $a=70 x 10^{-6}$

Force $F=7N$

Generally the equation for Pressure is mathematically given by

Pressure = Force/Area

$P=\frac{F}{A}$

$P=\frac{ 7}{(70 * 10^{-6})}$

$P= 1*10^{5} Pa$

Generally the equation for Pressure is also mathematically given by

$P=hpg$

Therefore

$h=\frac{P}{hg}$

$h=\frac{10000}{1000*9.8}$

$h=10m$
