Vedclass · Answer

(a) $\frac{{{h_1}}}{{{h_2}}} = \frac{{{ho _1}}}{{{ho _2}}} = \frac{{(1 + \gamma \,{	heta _1})}}{{(1 + \gamma \,{	heta _2})}}$  $\left[ {\because \,ho  = \frac{{{ho _0}}}{{(1 + \gamma 	heta )}}} ight]$

$\Rightarrow$ $\frac{{50}}{{60}} = \frac{{1 + \gamma 	imes 50}}{{1 + \gamma 	imes 100}}$ $\Rightarrow$  $\gamma = 0.005/^\circ C$
