What is Physical World & Measurements Notes about?

The document discusses dimensional analysis of various physical quantities. It provides questions related to finding the dimensions of variables in different physical relations. Some key points: - The dimensional formula for universal gravitational constant G is [M-1L3T2]. - The velocity V of water depends on its wavelength λ, density ρ, and acceleration due to gravity g as: V = Kλ1/2ρ0g1/2 - Dimensions of angular frequency ω is [T-1] and wave number k is [L-1] in the relation: Y = sin(ωt – kx). - Dime
