Solution to problems – class 9 – Set 1 Q 60

Problem Statement 60) A metallic sphere of mass 2 kg and volume 2.5 x 10-4 m3 is completely immersed in water. Find the buoyant force exerted by water on the sphere. Density of water = 1000 kg/m3 Solution Volume of the water displaced = volume of the completely immersed sphere=2.5 x 10-4 m3 Mass of […]

Viscosity – definition, derivation, coefficient of viscosity

Viscosity – coefficient of viscosity  When we pour a glass of water, it flows freely and quickly. But when we pour honey that flows slowly and sticks to the container. The cause behind this difference is fluid friction, both within the fluid itself and between the fluid and its surroundings (say container wall). We call […]
