The coefficient of linear expansion `'alpha`' of a rod of length `2` m varies with the distance x from the end of the rod as ` alpha = alpha_(0) + alpha_(1) "x" ` where `alpha_(0) = 1.76 xx 10^(-5) "^(@)C^(-1)"and" alpha_(1) = 1.2 xx 10^(-6)m^(-1) "^(@)C^(-1)`. The increase in the length of the rod. When heated through `100^(@)C` is :-
