1.	Two slabs A & B having lengths l_(1)andl_(2), respectively, and same cross - section have thermal conductivities K_(1)andK_(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 B in a given time is
Answer» `K_(1)/l_(1):K_(2)/l_(2)` `K_(1)/l_(2):K_(2)/l_(1)` `K_(1)l_(1):K_(2)l_(2)` `L:l` ANSWER :D
