80. Two metal rods, 1 & 2 of same length have same 8 temperature difference between their ends, their
thermal conductivities are K, & K, and cross
sectional areas A, & A, respectively. What is
required condition for same rate of heat conduction
in them.
(1) K1= K2
(2) K1 A, - K2 A,
(3) K1/A1=K2/A2
(4)K1/l1^2=K2/l2^2
​

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

      2

  2 is to go somewhat to the top right of a because it is squared
