Answer 2

▪︎The area of sharp edge of knife, scissor or handsaws are much less then blunt edge. So, for same total force pressure is more for sharp edges than the blunt one. Hence sharp knife, scissors etc, cuts easily than a blunt one.

▪︎High heeled shoes sink deeper in soft ground in comparison to flat ones, This is because in high heeled shoes weight is spread over a small area in comparison to flat ones. This results in higher pressure. 

▪︎Broad handles in bags and suitcases are provided for the comfort. Broad handles have large area. So, the pressure exerted on hands and shoulders would be small while carrying the bags and the suitcases.

▪︎Trucks carrying heavy loads have more than four tyres. More tyres in case of trucks increase the area of contact with the road. This results in reduced pressure on the tyres. 

▪︎On squeezing the rubber top on the dropper the air is squeezed out. Now when you put the tip of dropper into the liquid and stop squeezing the top, the low pressure inside inl flows inside and fill the void. The ink stays in dropper due to the lower pressure in the tube than the external atmospheric pressure.
