Answer:Since, the length of the wire becomes 6/5 times its original length; hence there will definitely be some change in cross sectional area. Now we know that, volume = Mass/Density and since neither mass nor density has changed due to change in length, thus volume must remain constant. Thus, R2 = 1.44 *25 = 36 Ohm.
