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 %3D 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. 2 W O 4 W O 3 W 5 W O 6 W
