These question consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five responses. Assertion: Two conducting rods of material and same lengths are joined end to end as shown in figure. Heat current H is flowing through them as shown. Temperature differences across rod-1 is more than the temperature difference across of rod-2.

1.	These question consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five responses. Assertion: Two conducting rods of material and same lengths are joined end to end as shown in figure. Heat current H is flowing through them as shown. Temperature differences across rod-1 is more than the temperature difference across of rod-2.
Answer» If both Assertion and REASON are correct and Reason is also a good ABSORBER of RADIATION at a given wavelength. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. If Assertion is true but Reason is false If Assertion is false but Reason is true. Solution :`R = 1/(KA)` or `Ralpha1/A` `R_(1)gtR_(2)` Further, TD=`HxxR` or `TD alpha R` `therefore` `(TD)_(1) GT (TD)_(2)`
