The electric aluminum wire with a diameter of $0\mathrm{.}5$ mm is covered with vinyl plastic with a thickness of $1\mathrm{.}5$ mm$.$ A current with a strength of $6$A flows through the wire. The temperature of the surrounding environment is $10\backslash$deg C$,$ but the heat transfer coefficient is $16$ W$/$m$2$K$.$ Find the temperature on the surface of the wire and on the surface of the insulation, and the power of the internal heat sources. The specific electrical resistance of aluminum $2,62$ x $10^-8$ Om x m$.$
