The drawing shows an arrangement in which a block (mass = 18.0 kg) is held in position on a frictionless incline by a cord (length = 0.733 m). The mass per unit length of the cord is 1.79 x 102 kg/m so the mass of the cord is negligible compared to the mass of the block. The cord is being vibrated at a frequency of 124 Hz (vibration source not shown in the drawing). What is the maximum value of the angle e in degrees at which a standing wave pattern exists on the cord? NumberT12.1 Units deg the tolerance is +/-9%
