Question

A force of 2.18x10^4 N is applied to a diver's face mask with an area of 125 cm^3. Find the pressure in atm on the face mask. (1 atm= 101,325 Pa)

A. 2.16 atm
B. 2.18 atm
C. 2.20 atm
D. 2.22 atm

Answer 1

We can use the following formula to determine the face mask's pressure in atm: Force/Area = Pressure. The pressure on the face mask is 172 atm. So, none of the given options are correct.

Step-by-step explanation:

To find the pressure in atm on the face mask, we can use the formula:

Pressure = Force/Area

First, let's convert the area of the face mask from cm³ to m^2:

Area = 125 cm³ * (1 m/100 cm)³ = 0.00125 m²

Now, let's convert the force from N to atm:

Force = 2.18x10⁴ N * (1 atm/101,325 Pa) = 0.215 atm

Finally, we can calculate the pressure:

Pressure = 0.215 atm / 0.00125 m² = 172 atm

Therefore, the pressure on the face mask is 172 atm.

None of the given options are correct.
