thats it itna he answer hai
formula mein put kro value u will get the ans
brooo the me the whole ans in detail
pleassss
formula is coefficient of linear expansion =change in length /original length ×rise in temp
thankxxxx brother
linear coff is 25×10 =80-0.1/80×(293-x)
from there u will get
ok bro
welcome
