Question

Calculate the pressure when a force of 100N.the act perpendicular to a surface of area 10cm square

Answer 1

pressure=force/area
=(100N)/(10/100 metres^2)
=(100/0.1)N/m^2
=1000 pascal.

Answer 2

Answer:

10x10^4 pa

Explanation:

Pressure is the amount of force applied perpendicular to the surface of an object per unit area. The symbol for it is "p" or P.

Pressure is defined as the measure of the force applied over a unit area. Pressure is often expressed in units of Pascals (Pa), newtons per square meter (N/m2 or kg/m·s2), or pounds per square inch. Other units include the atmosphere (atm), torr, bar, and meters sea water (msw).

so given Force = 100N

              Area = 10 cm²=10x10^-4 m²

        therfore  pressure (p) = force/area

                                              =100/10x10^-4

                                               =10x10^4 pa

The force acting on an object perpendicular to the surface is called thrust. Therefore thrust is 100N

hrust=Force=100N
