The ratio of thermal conductivity of two rods of different material is `5 : 4`. The two rods of same area of cross-section and same thermal resistance will have the lengths in the ratio

The ratio of thermal conductivity of two rods of different materials is "5:4. The two rods of same area and same thermal resistance will have lengths in the ratio :-

The ratio of the thermal conductivities of two different materials is 1 : 2 . The thermal resistance of the rods of these materials having the same thickness are equal. Find the ratio of the length of rods.

The ratio of thermal conductivites of two different metals is 5:3 . In order to have the same thermal resistance in these metals of equal thickness what should be the ratio of their length?

The ratio of thermal conductivites of two different metals is 5:3 . In order to have the same thermal resistance in these metals of equal thickness what should be the ratio of their length?

The ratio of the coefficient of thermal conductivity of two different materials is 5 : 3 . If the thermal resistance of the rod of same thickness resistance of the rods of same thickness of these materials is same, then the ratio of the length of these rods will be

Ratio of coefficient of thermal conductivity of two different material is 4 : 3. to have same thermal resistance of the two rods of these materials of equal thickness, what should be the ratio of their length ?
