A metal rod that is 30.0 cm long expands by 0.0650 cm when its temperature is raised from 0.0°C to l00.0°C. A rod of a different metal and of the same length expands by 0.0350 cm for the same rise in temperature. A third rod, also 30.0 cm long, is made up of pieces of each of the above metals placed end to end and expands 0.0580 cm between 0.0°C and l0.0°C. Find the length of each portion of the composite rod.
