Unformatted text preview: 15.76: a) The new tension F in the wire is F F B w (1 3w) water A1 w1 1 water 3 A1 w 1 (1.00 103 kg m3 ) 3(2.7 103 kg m3 ) (0.8765) w (0.87645) F . The frequency will be proportional to the square root of the tension, and so f (200 Hz ) 0.8765 187 Hz. b) The water does not offer much resistance to the transverse waves in the wire, and hencethe node will be located a the point where the wire attaches to the sculpture and not at the surface of the water. ...
