Two identical resistors are connected in parallel across a

Two identical resistors are connected in parallel across a 27-Vbattery, which supplies them with a total power of 6.5 W. While thebattery is still connected, one of the resistors is heated so thatits resistance doubles. The resistance of the other resistor remains unchanged. Find (a) the initial resistanceof each resistor, and (b) the total powerdelivered to the resistors after one resistor has been heated.
