Question

calculate the pressure exerted when a force of 450N is applied on an area of 90 m2 explain in 3 marks

Answer 1

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2..

Answer 2

Answer:

Explanation:

The pressure is given as Force/Area.

In this case, the area =10m  

2

and the presure acting is 45N/m  

2

.

Therefore, Force=Pressure×Area=45N/m  

2

×10m  

2

=450N.

Hence, the total force is 450 N.
