Question

the dimensional formula for w in the relation y= A sin wt is? ​

Answer 1

Answer:

Here A = Amplitude => [ A ] = [ L ]

and

Sine of any angle = Perpendicular / hypotenuse = Ratio of two sides of a Right angle triangle

=> sin ( wt ) is Dimensionless quantity i . e ,

Sin ( wt ) has no dimensions

therefore ,

Dimensional formula of y

= [ L ] = [ M^0 L^1 T^0 ]
