Question

Asla consists of two parallel layers of copper and brass of same thickness and having thermal conductivities in the ratio 1 by 4 is free surface of brass is at hundred degree celsius and that of corporate zero degree celsius the temperature of interfaces

Answer 1

Hey mate!!!!!

Here is your answer... .

The amount of heat flowing per second is :

dQ/dt = KA.dT/L

K1:K2 = 1:4

let temp. of junction is T , as heal flow rate is same

K1.(100-T) = K2.(T-0)

temp of junction is 20 C

hope it helps. ...

plz mark it as brainiest.....
