Two parallel back disks are positioned coaxially with a distance of 0.25 m apart. The lower disk is 0.2 m in diameter and the upper disk is 0.4 m in diameter. If the lower disk is heated electrically at 26 W to maintain a uniform temperature of 517 K, determine the temperature of the upper disk. (For coaxial parallel disks, i
