1.	Two slabs A& B having lengths 1_(1) and 1_(2), respectively, and same cross - section have thermal conductivities K_(1) and K_(2) respectively. They are placed in contact and a constant temperature difference is maintained across the combination. The ratio of the quantities of heat flowing through A and Bin a given time is
Answer» `(K_1)/( 1_1 ) : ( K_2)/( 1_2)` `(K_1)/( 1_2) : ( K_2)/( 1_1)` `K_1 1_1 : K_2 1_2` `1:1` ANSWER :D
