A hand-winding watch is controlled by a mechanism that includes a spiral wire and a wheel $2\mathrm{.}5$ mm radio. The rotational inertia of the wheel is$\mathrm{ 8}**10^-$¹¹Kg**m², and the frequency of its oscillation$\mathrm{from}$n is from$\mathrm{ 8}\mathrm{.}7\mathrm{ Hz}.$ Get and n the value of к for the coil spring.
