in a particular experiment Ramu use the relation `F=AB+(P+Q)Y` to calculate force. which principle is used to check the correctness of the equation.

Name the principle used to check the correctness of an equation.

in a particular experiment Ramu use the relation F=AB+(P+Q)Y to calculate force. in the dimensional formula of Y is M^0L^1T^(-1). then find the dimensional formula of P.

A company manufacturing PVC pipes claims in an advertisement that the volume of water flowing out through the pipe in a given time is as per the equation V=KA^2ut where A is the area of cross section of the pipe, u is the speed of flow, t is the time and K is a dimensionless constant. Name the principle that can be used to check the dimensional correctness of this equation.

A stone is thrown upwards from the ground with a velocity, u . a)What is the maximum height attained by the stone? b)Check the correctness of the equation obtained in,(a)using the method of dimensional analysis. c)Draw the position-time graph of the stone during its return journey

A stone is thrown upwards from the ground with a velocity u . What is the maximum height attained by the ball? Check the correctness of the equation thus obtained using the method of dimensional analysis.
