Question

The equation of wave is given as Y = A.sin w{x/v-K)]
Where w is the angular velocity and v is the linear
velocity. The dimension of K is : (RPMT - 931​

Answer 1

Answer:

Explanation:

dimension of v=dimension of k

lt^-1=dimension of k

Answer 2

Answer:

[T]

Explanation:

Compare this equation with the equation

Y=Asin(wt)

We find that..

(x/V-K) = t {dimensionaly}

Here x=distance and v =velocity

So definitely unit of x/v must be 'second'

And we know that same physical quantities can be added or subtracted with each other.

So in the equation (x/V-K)

K must have the unit of time, i. e . Unit is second and dimension is [T].
