Question

the front and back sides of a person has an area of 900 square inches each side. what is the total force of the atmosphere pressing on this person from the front side?​

Answer 1

`5.9\cdot 10^4 N`

Step-by-step explanation:

First of all, let's convert the area of the front side of the person into
`m^2`:

`A=900 in^2=0.58 m^2`

And the atmospheric pressure is

`p=1.01 \cdot 10^5 Pa`

The force pressing on this person from the front side is

`F=pA`

and substituting the values of the pressure and the area, we find

`F=(1.01 \cdot 10^5 Pa)(0.58 m^2)=58,580 N=5.9\cdot 10^4 N`
