65. The current in the 8.00 2 resistor in the given figure is 0.500 A. Find the current in (a) the 20.0 12 resistor and in (b) the 9.000 ohm resistor ​

Does anyone know how to solve this problem? i really need . i made an attempt but i just cant get it. a metal rod is 25.000 cm long at 25.0 degrees celsius. when heated to 102.0 degrees celsius, it is 25.054 cm long. what is the coefficient of linear expansion for this metal.
