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 \(\left(\alpha_{F e}=11 \times 10^{-6 \circ} c^{-1}, \alpha_{c u}=17 \times 10^{-60} c^{-1}\right)\)

366760 A bimetallic strip consists of metals \(X\) and \(Y\). It is mounted rigidly at the base as shown. The metal \(X\) has a higher coefficient of expansion compared to that for metal \(Y\). When bimetallic strip is placed in a cold bath,

366761 \(P Q R\) is a right angled triangle made of brass rod bent as shown. If it is heated to a high temperature the angle \(PQR\).

366762 A pendulum clock (fitted with a small heavy bob that is connected with a metal rod ) is 5 seconds fast each day at a temperature of \(15^\circ C\) and 10 seconds slow at a temperature of \(30^\circ C\). The temperature at which it is designed to give correct time, is

366763 Two rods \(A\) and \(B\) of identical dimensions are at temperature \(40^\circ C.\) If \(A\) is heated upto \(160^\circ C\) and \(B\) upto \(T^\circ C\) then new lengths are the same. If the ratio of the coefficients of linear expansion of \(B\) and \(A\) is \(2: 5\), then find the value of \(T\) is
