ICSE Class 9 Physics Simple daily life examples
Recall high-pressure exertion in a small surface area
Fluids exert the same pressure in all directions at the same level. The example satisfies the statement
A barometer measures air pressure, Altimeter measures altitude, Manometer measures pressure difference, Lactometer used to test milk's purity
Iron nail has lesser density than that of mercury
Recall pressure and thrust.
A dam has broader walls at the bottom than at the top. As, the depth increase, the pressure applied by water on the walls of the dam also increases.
The buoyant force depends on the body's volume, density of the liquid, and acceleration due to gravity.
Buoyancy or upthrust refers to an upward force exerted by a fluid that opposes the weight of a partially or fully immersed object
The Archimedes principle states that upward buoyant force is exerted on a body immersed in a fluid, whether fully or partially, is proportional to the weight of the fluid that the body displaces.
Calculate the pressure first by the getting product of (h x rho x g).Then calculate thrust =pressure x area
