The temperature of the two outer surfaces of a composite slab, consisting of two materials having coefficients of thermal conductivity K and 2K and thickness x and 4x, respectively are T2 and T1(T2>T1). The rate of heat transfer through the slab, in a steady state is (A(T2−T1)K/x) f, with f equals to (a) 1 (b) 1/2 (c) 2/3 (d) 1/3
