The pressure of a fluid varies with depth h as P = P₀ + ρgh, where ρ is the fluid density. This expression is associated with

If two miscible liquids of same volume but different densities ρ₁ and ρ₂ are mixed, then the density of the mixture is given by

A metallic sphere of mass 1 kg and volume 2 × 10⁻⁴ m³ is completely immersed in water. The buoyant force exerted by water on the sphere is: (Given: density of water = 1000 kg/m³, g = 10 m/s²)

The immersed portion of a piece of pure ice floating in water is

With the rise of temperature, the viscosity of liquid :
