The unit of K is A.Hertz

Displacement General equation : x=A Sin(Kt) where

A= amplitude , t=time and K=frequency. Hence the unit of K is Hertz.

Answer: Hertz

Explanation: As the displacement of a particle is given byx = A sin^2 (Kt), where t denotes the time.

As the displacement of particle  x=A^2 sin^2(kt)

x=A^2sin^2

∅=kt (Where ∅ is an angle→Dimensionless)

kt → dimensionless,

[k] = \frac{1}{[t]}=T^-^1

As we know, the formula of frequency → [M^0L^0T^-^1]

As frequency = Hertz.

Hence, the unit of K hertz.
