366734 A copper rod of \(88\;cm\) and an aluminium rod of unknown length have their increase in length independent of increase in temperature. The length of aluminium rod is :\(\left(\alpha_{c u}=1.7 \times 10^{-5} K^{-1}\right.\) and \(\left.\alpha_{A l}=2.2 \times 10^{-5} K^{-1}\right)\)

366735 The figure shows a rectangular brass plate at \(0^\circ C\) in which there is a rectangular hole of dimensions indicated. If the temperature of the plate is raised to \(150^\circ C\).

366736 An iron rod of length \(50\;cm\) is joined at an end to an aluminium rod of length \(100\;cm\). All measurements refer to \(20^\circ C\). The coefficients of linear expansion of iron and aluminium are \(12 \times {10^{ - 6}}/^\circ C\) and \(24 \times {10^{ - 6}}/^\circ C\), respectively. The length of composite system is:
