366759 The design of some physical instrument requires that there be a constant difference in length of \(10\;cm\) between an iron rod and a copper cylinder laid side by side at all temperatures. The lengths are \(\left(\alpha_{F e}=11 \times 10^{-6 \circ} c^{-1}, \alpha_{c u}=17 \times 10^{-60} c^{-1}\right)\)
