The bottom of a box has a surface area of 25.0 cm2. The mass of the box is 34.0 kilograms. Acceleration due to gravity at sea level is 9.80 m/s2. What pressure is exerted by the box where it rests?

Respuesta :

pcyjp2
weight =mg = 333.2 N 
pressure = force/area = 333.2/25=13.328 N/cm^2 

Answer:

Pressure, P = 133280 pascal

Explanation:

Given that,

Surface area of the box, [tex]a=25\ cm^2=0.0025\ m^2[/tex]

Mass of the box, m = 34 kg

To find,

The pressure exerted by the box

Solution,

The force acting per unit of area is called the pressure exerted. Its expression is given by :

[tex]P=\dfrac{F}{A}[/tex]

[tex]P=\dfrac{mg}{A}[/tex]

[tex]P=\dfrac{34\times 9.8}{0.0025}[/tex]

P = 133280 pascal

So, the pressure exerted by the box is 133280 pascal.
