A string of linear mass density 2.25 g/m is stretched by the weight of an adjustable mass m as shown. Near the end of the string a vi- brator is attached at a constant but unknown frequency; the length of the string which vi- brates is 2.74 m. For some values of the mass mn, the string resonates with the vibrator's frequency and levelops visible standing waves and n anti- nodes between the vibrator and the pulley. A lab student who performed this experi- ment recorded two consecutive resonances for Mn = 1.69 kg and for mn-1 = 1.96 kg. Unfor- tunately, he forgot to record the actual node numbers for the resonances but only recorded that there were no resonances for any masses between 1.69 kg and 1.96 kg. 2.74 m vibrator 2.25 g/m M18 How many antinodes did the resonant wave have for 1.69 kg? 031 (part 2 of 2) 10.0 points What is the frequency of the oscillator?
