Answer:
a) As we know pressure(P=F/A) i.e.less the area more will be the pressure.The surface area of a sharp nail is less than that of a blunt nail. Hence having more pressure, a sharp nail pierces more easily through wood than a blunt nail.
c) As we know pressure(P=F/A) i.e.less the area more will be the pressure. The foot of camel is wider than that of a horse and less pressure is applied on the sand as a result, the foot of camel do not sink in sand. So, a camel moves easily through a desert than a horse.
