Question

Two rods of same length and transfer a given amount of heat 12 second, when they are joined as shown in figure (i). But when they are joined as shown in figure (ii). then they will transfer same heat in same conditions in (A) 24 s (B) 13 s (C) 15 s (D) 48 s

t propto (ℓ/A), t prime propto (2 ℓ/A / 2)

Q. Two rods of same length and transfer a given amount of heat $12$ second, when they are joined as shown in figure
(i). But when they are joined as shown in figure
(ii). then they will transfer same heat in same conditions in

24 s

13 s

15 s

48 s

$t \propto \frac{ℓ}{A}, t^{'} \propto \frac{2 ℓ}{A /2}$
