1.Consider a compound slab consisting of two different materials having equal thickness and thermal conductivities KKK and 2K2K2K, respectively. The equivalent thermal conductivity of the slab is:a.43K\frac{4}{3}K34Kb.2K\sqrt{2}K2Kc.3K3K3Kd.KKKLogin to continueOnly logged in users canattempt or see the solution.
