A wall has two layers A and B made of two different materials thermal conductivities K_A and K_B ( K_A = 3K_B ). The thickness of both the layers is same. The temperature across the wall is 20^@C in thermal equilibrium. Then

The kinetic energies of a planet in an elliptical orbit about Sun, at positions A, B and Care K_A, K_B and K_C respectively. AC is the major axis and SB is perpendicular to AC at the position of the Sun S as shown in the figure. Then

Two reaction A to products and B to products have rate constants k_A and K_B at temperature, T and activation energies E_A and E_B respectively. If K_A gt K_B & and E_A lt E_B and assuming that A for both the reactions is same then:
