19. A weight on a spring stiffness k varies in the liquid, the frequency of its oscillations ω half the natural frequency ω0 CW weight on the same spring. The coefficients of the spring stiffness k increased 7 times. How many times it is necessary to increase the viscous friction coefficient of the liquid to the period of oscillation of the sinker has not changed
