A tire pump has a piston whose cross-sectional area is 0.005 m2. If we apply a force of 350 N to the piston, find the pressure on the air in the pump.

Sagot :

Pressure = [tex]\frac{F}{A}[/tex]

[tex]= \frac{350}{0.005}[/tex]

= 70000 pa

*pa is pascals

Answer:

Step-by-step explanation:

To find the pressure on the air at the surface of the pump, we can use the equation P=F/a, where P is the total pressure on the surface,  F is the amount of force exerted on the surface, and a is the area of the surface.

All we need now is to properly identify the values in which the equation requires find the pressure:

a  = 0.005 m^2                                               F = 350 N

and now, we can plug in and solve:

P=F/a

P=(350 N)/(0.005 m^)

P=70000 N/m^2, which is our final answer.
