In the arrangement shown in Figure P18.27, an objectof mass m 5 5.00 kg hangs from a cord around a lightpulley. The length of the cord between point P and thepulley is L 5 2.00 m. (a) When the vibrator is set to afrequency of 150 Hz, a standing wave with six loops isformed. What must be the linear mass density of thecord? (b) How many loops (if any) will result if m ischanged to 45.0 kg? (c) How many loops (if any) willresult if m is changed to 10.0 kg?
