1.	State the meaning of 1 pascal. A boy of mass 40 kg is standing on loose sand . If the area of his feet is 0.04 m .Find the pressure exerted by boy on sand . ( g=10 m\s)
Answer» 1 pascal is the pressure exerted or experienced by a body or OBJECT when a thrust of 1 N acts on an area of 1 metre.sq. Mass of boy = 40 kg Weight of Boy= 40 × g = 40 × 10 = 400 N Area = 0.04m.sq Pressure = Force/Area = 400/0.04 = 400 × 100 / 4 = 100 × 100 = 10000 PA
