1. State the reason, , a] It is easy to cut vegetables using a sharp knife, , * The tip of the knife has a smaller surface area. So that more, pressure is felt there making it easier to cut objects., , b] The number of tyres is more for goods vehicles, , * By increase the number of tyres in increases the surface area on, which the load of the goods vehicles is felt. Thereby reducing the, pressure., , Liquid Pressure, , * Which balloon has expanded more?, Cc, , * What may be the reason? A, Liquid Pressure ( The liquid pressure increase as depth increase), , |, * How can the expansion of balloon be related to the depth of 7 Gu, the level of liquid in the pipe? ¢, , The pressure experienced in liquids depend on the height of, the liquid column above it. The liquid pressure increase as depth, increase and vice versa, , , , |* The thrust acting per unit area by a liquid is liquid pressure, * Liquids exert force on all sides of the container in which they are, taken., , |* The pressure exerted by a liquid column increases with increase in, height.
