Ashmeeta Bhattarai asked: "What are limitations of principle of homogeneity of dimensional analysis?" The dimensional analysis has the following limitations It fails while using it to derive a relation among physical quantities, if there are more than 3 unknown variables on which a given physical quantity depends It does not tell whether a given Physical … Continue reading Limitations of Dimensional Analysis
Shashank Asked: "How to solve rain and man problems from motion in one dimension?" Answer: The problem is solved using principles of vector addition. There is a simple logic to remember A/C = A/B x B/C If we represent diagrammatically (in the form of vectors) the velocity of rain wrt ground, velocity of man wrt … Continue reading Rain and Man problems – How to solve?
Binay Sharma asked: "Explain the applications of the Principle of homogenity of Dimensions and its importance" Principle of homogenity of dimensions states that "For an equation to be dimansionally correct, the dimensions of each term on LHS must be equal to the dimensions of each term on RHS." Applications 1. To determine the dimensions of … Continue reading Principle of Homogenity of Dimensions
