Floatation Class 9 Important Questions and Answers Science Chapter 16. (iv) Small contact area. P = Force/Area. Its SI unit is Newton. Question 1. find the pressure exerted by the block on the table. unit is 'newton'. Initial velocity (u) =15m/s. Pressure : Thrust acting on a unit are is called pressure. Ans: Pressure is given as force/area so, Force, F = mg = 1000 X 981 gm.m/s 2. and area, A = 1x1 cm 2 = 1 cm 2. 3. Correct Option is : 1. Below you can download the notes of Properties of Matter, which is the 7th chapter. It is the phenomenon that governs the movement of heavenly bodies such as stars and planets and keeps one stuck on the ground and makes objects fall from a height. Thrust : Force acting on an object perpendicular to the surface is called thrust. F = . Pressure of water due to height (h) = hρg. P = F/A. Ans: Pressure is given as force/area so, Force, F = mg = 1000 X 981 gm.m/s 2. and area, A = 1x1 cm 2 = 1 cm 2.
