Two identical rectangular rods of metal are welded end to end in series between temperatures of `0^(@)C` and `100^(@)C` and `10 J` of heat is conducted (in a steady state process) through the rods in `2.0min`. How long would it take for `10J` to be conducted through the rods if they are welded together in parallel across the same temperatures ?

Two identical rectangular rods of metal are welded end to end in series between temperature 0^(@)C and 100^(@)C and 10 J of heat is conducted (in steady state process) through the rod in 2.00 min. if 5 such rods are taken and joinded as shown in figure maintaining the same temperature difference between A and B, then the time in which 20 J heat will flow through the rods is

Two identical rectangular rods of metal are welded as shown in figure (1) and 20 J of heat flows through the rods in 1 min . How long would it take for 20 J heat to flow through the rods if they are welded as shown in figure (2)

Two identical rods of same metal are first waleded in series and then in parallel are maintained at same temperature difference then the ratio of heats conducted in same time is .

Two identical square rods of metal are welded end to end as shown in figure (a). Assume that 10 cal of heat flows through thr rod in 2min . Now the rods are welded as shown in figure (b). The time it would take for 10 cal to flow through the rods now, is

Two identical square rods of metal are welded end to end as shown in fig (1) . 20 cal of heat flows through it in 4min . If the rods are welded as shown in fig. (2) , the same amount of heat will flow through the rods in

Two identical square rods of metal are welded end to end as shown in figure (i), 20 calories of heat flows through it in 4 minutes. If the rods are welded as shown in figure (ii), the same amount of heat will flow through the rods in

Two ends of a conducting rod of varying cross-section are maintained at 200^(@)C and 0^(@)C respectively. In steady state:

Which of the following cylindrical rods will conduct most heat, when their ends are maintained at the same steady temperature
