The top of your head has a surface area of 25 cm x 25 cm. How many newtons of force push on your head at sea level? ?
If you estimate this area to be 100 in2, what is the force in pounds?

Using the realtion,
F = PA
a) The area is = 0.25*0.25 = 0.0625m2.
P is atmospheric pressure = 101325 Pa.
The Force F = PA = 6332.8N.
b) The area given is = 100 in2.
P is atmospheric pressure = 14.7 psi
The Force F = PA = 1400 lb.
I hope you understood the problem, If yes rate me!! or else comment for a better solution.
Please Rate me!! It keeps me going. Thank you
