Question

Define Pressure.What is its SI unit?
If a force of 5 N is applied over an area of 5 cm 2 ,calculate the pressure
Produced.

Answer 1

Answer:

Pressure = Force applied on an unit area is called pressure.

SI unit Of pressure is pascal (pa).

Pressure = Force / Area

Pressure = 5N / 5cm

Pressure = 1 pascal

Hope it helps you.

Answer 2

Answer:

Explanation:

Pressure: Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

SI unit of pressure:The SI unit for pressure is the pascal (Pa), equal to one newton per square metre.

pressure=pressure divided by area (formula)

               = 5N divided by 5cm 2(square not 2)

               =calculate it.

hope it helps.
