A mass m hangs on a string that is connected to the ceiling. You pluck the string just above the rhassr 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 ciecreaseclr if the mass m is increased by a factor of 3.41. {Assume that the string does not stretch in either case and the contribution of the mass of the string to the tension is negligible.) : A particular steel guitar string has mass per unit length of 1.87 g/m. a) If the tension on this string is 52.3 N, what is the wave speed on the string? Submit Answer Tries 0/99 b) For the wave speed to be increased by 1.51 %, by what percentage should the tension be increased? Do not enter unit. Submit Answer Tries 0/99A string is 42.5 cm long and has a mass per unit length of 6.03-10"* kg/m. What tension must be applied to the string so that it vibrates at the fundamental frequency of 605 Hz? Submit Answer Tries 0/99
