To solve the problem, we need to determine the lengths of an iron rod (L1) and a copper ruler (L2) at 0°C given that the difference in their lengths at 50°C and 450°C is the same and equal to 2 cm. The coefficients of linear expansion for iron and copper are given as follows: - Coefficient of linear expansion of iron (α1) = 12 × 10^(-6) /K - Coefficient of linear expansion of copper (α2) = 17 × 10^(-6) /K ### Step-by-Step Solution: 1. **Understanding Linear Expansion**: ...
