Two rods of same length and area of cross-section `A_(1)" and" A_(2)` have their ends at the same temperature. If `K_(1) "and" K_(2)` are their thermal conductivities, `c_(1) "and" c_(2)` are their specific heats and `d_(1) "and "d_(2)` are their densities, then the rate of flow of heat is the same in both the rods if

Two rods of same length and areas of cross section A_1 and A_2 have their ends at same temperature. If K_1 and K_2 are their thermal conductivities, C_1 and C_2 their specific heats and rho_1 and rho_2 are their densities, then the condition that rate of flow of heat is same in both the rods is

Two rods of same length and areas of cross section A_1 and A_2 have their ends at same temperature. If K_1 and K_2 are their thermal conductivities, C_1 and C_2 their specific heats and rho_1 and rho_2 are their densities, then the condition that rate of flow of heat is same in both the rods is

Two rods of same length and areas of cross-section A_(1) and A_(2) have their ends maintained at same temperature. If K_(1) and K_(2) are their thermal conductivities, c_(1) and c_(2) are the specific heats of their material and rho_(1),rho_(2) their densities, then for the rate of flow by conduction through them to be equal

Two rods of the same length and areas of cross-section A_1 and A_2 have their ends at the same temperature. K_1 and K_2 are the thermal conductivities of the two rods. The rate of flow of heat is same in both the rods if-

Two different metal rods of equal lengths and equal areas of cross-section have their ends kept at the same temperature theta_(1) and theta_(2) . if K_(1) and K_(2) are their thermal conductivities, rho_(1) and rho_(2) their densities and S_(1) and S_(2) their specific heats, then the rate of flow of heat in the two rods will be the same if:

Two different metal rods of the same length have their ends kept at the same temperature theta_(1) , and theta_(2) with theta_(2) gt theta_(1) . If A_(1) and A_(2) are their cross-sectional areas and K_(1) and K_(2) their thermal conductivities, the rate of flow of heat in the two rods will be the same it:

Two metal rods 1 and 2 of same lengths have same temperature difference between their ends. Their thermal conductivities are K_(1) and K_(2) and cross sectional areas A_(1) and A_(2) respectively. If the rate of heat conduction in 1 is four times that in 2, then

Two metal rods 1 and 2 of same lengths have same temperature difference between their ends. Their thermal conductivities are K_(1) and K_(2) and cross sectional areas A_(1) and A_(2) respectively. If the rate of heat conduction in 1 is four times that in 2, then
