12. Body weight m = 0,6 kg, suspended from the helical spring stiffness k = 30 N / m, in some medium makes elastic vibrations. Logarithmic decrement Θ = 0,01. Determine: 1) time during which the amplitude of the oscillations is reduced by 3 times; 2) the number of complete oscillations that should make the weight, was similar to a decrease in amplitude.
