A string is attached - vertically - from one end to a vibrator and from the other end to a block of mass m 1.8 kg. The power delivered to produce a wave on this string is P 12 W. Assume that the block is replaced by a lighter one with a mass m' = 0.45 kg. Determine the new power, P', required to generate a wave with the same amplitude and frequency.
