if the original length are at 40.0∘C?
A metal rod (A) of 25cm length expands by 0.050cm when its temperature is raised from 0∘C to 100∘C. Another rod (B) of a different metal of length 40cm expands by 0.040cm for the same rise in temperature. A third rod ( C) of 50cm length is made up of pieces of rods (A) and (B) placed end to end expands by
