A steel wire has a mass of `50 g//m` and is under tension 450N.
(a) Find the maximum average power that can be carried by the transverse wave in the wire if the amplitude not to exceed 20% of the wavelength. (b) The change in maximum average power if the mass per unit length of the wire is doubled. `(Use pi^(2)~=10.)`
