In the arrangement shown in the figure below, an object of mass m = 2.0 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L = 2.0 m. (Ignore the mass of the vertical section of the cord.) Vibrator - (a) When the vibrator is set to a frequency of 170 Hz, a standing wave with six loops is formed. What must be the linear mass density of the cord? kg/m (b) How many loops (if any) will result if m is changed to 72.0 kg? (Enter 0 if no loops form.) loops (c) How many loops (if any) will result if m is changed to 14 kg? (Enter 0 if no loops form.) loops
