What is the pressure in Pascals exerted on a surface measuring 0.5 m^2 by a force of 125 N?

To find the pressure exerted on a surface, you need to divide the force applied by the area of the surface.

Given:
Force = 125 N
Surface area = 0.5 m^2

To calculate the pressure, divide the force by the area:

Pressure = Force / Area

Substituting the values, we have:
Pressure = 125 N / 0.5 m^2

Now we can do the calculation:
Pressure = 250 N/m^2

Therefore, the pressure exerted on the surface is 250 Pascals (Pa).
