1. a. What is the pressure on a surface when a force of 500 N acts on an area of 2 m2 ​

250 pascal

Explanation:

Pressure is defined as the force me unit area

Mathematically:

Pressure = Force/area

i.e = P=F/A

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
