Answered by virajkumar

use formula l=alpha(1+change in length ×temp) where alpha is temp coeffi

Eddysolanki: thats it itna he answer hai

virajkumar: formula mein put kro value u will get the ans

Eddysolanki: brooo the me the whole ans in detail

Eddysolanki: pleassss

virajkumar: formula is coefficient of linear expansion =change in length /original length ×rise in temp

Eddysolanki: thankxxxx brother

virajkumar: linear coff is 25×10 =80-0.1/80×(293-x)

virajkumar: from there u will get

virajkumar: ok bro

virajkumar: welcome
