Question

a force of 1000n is applied to a surface it creates a pressure of 2000pa calculate the area of the surface

Answer 1

Explanation:

Pressure is defined as the force exerted (on a surface) per unit surface area.

Pressure is a scalar. P = F/A, Newton / meter?.

There are also some other units in use for pressure. Its unit is Pascal = 1) F= P* A = 50, 000 Pascals * 0.5 meter 25, 000 Pascals or N/m2 2)

Surface Area A = Force / Pressure = 100 N / 500 pa = 1/5 m2 3) Area = 30 cm? = 30 / (100*100) meter?

Pressure = F/A = 300 N / (3/1000) = 100 * 1000 pa = 1* 10° pa 4) Area = 1 cm² = (1/100)² meter? Force needed = PA = 20, 000 pa (1/1002) m² = 2 Newtons %3D
