A wire of length L=0.8 m is wire stretched by hanging a mass of M=0.05 kg. After applying an alternating current with a frequency of f, u magnet a constant magnetic field is produced by the U-type magnet. Under these conditions, resonance occurs and Bower source hanging mass antinodes and nodes are formed in the wire as shown in the figure. a) Write the number of antinodes (N) formed in the wire. b) Calculate the frequency of alternating current, f, if the mass per unit length of the wire is u=1.25x10° kg/m. (g= 10 m/s³)
