A 12.0-kg object hangs in
equilibrium from a string with a total length of L = 5.00 m and a linear
mass density of 0.001 00 kg/m. The string is wrapped around two light,
frictionless pulleys that are separated by a distance of d = 2.00 m (see
the tension in the string.
what frequency must the string between the pulleys vibrate in order to form the
standing wave pattern shown in figure b?
