A mercury in glass thermometer has a stem of internal diameter 0.06 cm and contains 43 g of mercury. The mercury thread expands by 10 cm when the temperature changes from `0^@C` to `50^@C`. Find the coefficient of cubical expansion of mercury. Relative density of mercury `=13.6` and `alpha_("glass")=9xx10^(-6)//K`.
