A long metal wire with a linear density of p = 10 g/ m is characterized by a tension T = 400 N. A 10 W vibrator is connected to one of its ends. The maximum transverse displacement of the wire points is yo = 1 mm. An energy absorber is connected to the other end of the wire, from which the wave is not reflected. Determine the frequency of the vibrator. Give your answer in Hz, rounded to the nearest whole number.
