If you dive underwater, you notice an uncomfortable pressure on your eardrums due to the increased pressure. The human eardrum h
irinina [24]

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

What does it mean when the mark on the ramrod disappears into the barrel of the muzzleloader?
bagirrra123 [75]

The firearm is unloaded.


The ramrod establishes whether the firearm is loaded or unloaded. It thrusts the bullet down the barrel. It is marked by wrapping some tape around it ( at the muzzle end ). This is to effectively signal if the muzzleloader is empty or loaded.
