Question

y= a sin 2πvt/k, where v is the velocity at instant t. For the equation to be dimensionally correct ,what should be dimensions of 'k'?

Answer 1

Answer:

Explanation:

Given Y = A  sin ( wt -  kx);  also it is given that it is time and X is the distance.The given equation is in the form of Y equal to a sin theta where  theta = (  WT- kx)

Hence we can say (wt-kx) is unitless  

Now we can say WT equal to  

Now we can say kx equal to
