In the arrangement shown in the figure below, an object of mass m = 4.00 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L = 2.00 m. (Ignore the mass of the vertical section of the cord.) Vibrator (a) When the vibrator is set to a frequency of 168 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 36.0 kg? (Enter 0 if no loops form.) (c) How many loops (if any) will result if m is changed to 10.0 kg? (Enter o if no loops form.)
