In the figure below, a cord is attached to an oscillator and wrapped around a light pulley where it is attached to a block with a mass, m = 4.0 kg. The length of the cord among point P and the pulley is L = 1.5 m.
1) When the vibrator is set to a frequency of 155 Hz, a standing wave with six loops is formed. What should be the linear mass density of the cord?
__________kg/m
2) How many loops (if any) will result if m is changed to 5.76 kg?
_______loops
3) How many loops (if any) will result if m is changed to 9.00 kg?
_______loops
