97. The load mass m = 50 g, is suspended on a string of length l = 20 cm, oscillates liquid. The drag coefficient of r = 0,02 kg / s. On the cargo acts driving force F = 0,1cosωt, N. Determine: 1) the frequency of the driving force, in which the maximum amplitude of the forced oscillations; 2) the resonance amplitude.
