1.	A brick is 40 cm. long, 10 cm. wide and 10 cm. thick. It weighs 20 N lying on the ground. Find the pressure exerted by the brick on the ground.
Answer» PRESSURE EXERTED on the brick at bottom is DUE to the FORCE exerted by its weight divided by its area. Pressure= Force / Area Where F=16N area= lengthx breadth area=32cmx10xcm=(32/100)mX( 10/100 )m =0.32m x0.1m=0.032m² Pressure=16/0.032=500N/m² Pressure exerted by the brick is 500N/m² or 500 PaExplanation:
