Question

Rod A and rod B are cylindrical rods made of the same metal. amd they differ only in size. Rod B has double the length and double the width of rod a. In an experiment, rod A is found to comduct heat at a rate of 25 W between a hot reservoir and a cold reservoir. At what width of rod A. rate will rod B conduct heat between the same two reservoirs?

A.12.5 W
B.100 W
C. 25 W
D.50 W
E. 200 W

Answer 1

Answer:B.100 W

Step-by-step explanation:

Answer 2

it would take rod B twice as much time

Step-by-step explanation:

it would take rod B twice as much time as it is twice as thick and twice as long. Due to this reason it would take the electric charge not only more time but even more voltage to travel through the rod
