You pluck the string just above the mass, and a wave pulse travels up to the ceiling, reflects off the ceiling, and travels back to the mass. Calculate the fraction that the round-trip time will be decreased, if the mass m is increased by a factor of 4.31. (Assume that the string does not stretch in either case and the contribution of the mass of the string to the tension is negligible.) .2076 Submit Answer Incorrect.
