One end of a light uniform rod is attached to a wall by a frictionless hinge. The rod is held in a horizontal position by a wire that runs from the other end of the rod to the wall. The wire has length 3.00 m and makes an angle of 30.0° with the rod. A block with mass m is suspended by a light rope attached to the middle of the rod. The transverse fundamental standing wave on the wire has frequency f. The mass m is varied and for each value the frequency is measured. You plot f2 versus m and find that your data lie close to a straight line with slope 22.4 kg 1. Part A What is the mass of the wire? Assume that the change in the length of the wire when the tension changes is small enough to neglect. Express your answer with the appropriate units.
