Option b is correct because alpha is equal to the expression in option b..

Option A s incorrect because it is the final expression for change in length due to expansion.

B is correct.

Co-efficient of linear expansion is equal to delta L divided by L delta T. The answer here is wrong because the given answer for change in length.

The co efficient of linear expansion is equal to__________?

Answer is Delta L is divided by L delta T. Alpha is the co-efficient of linear expansion, so correct it. Answer mark by you is for Only linear expansion is equal to delta L = alpha L delta T.

B is the right answer for the question. The marked answer is wrong due to what it says about the change in length.

Please answer clear kar dian which one is right.

Yes b is right ans because question is ask about co efficient of leaner expansion

B is the right answer, the question is about the coefficient of linear expansion not linear expansion so, correct answer is B

B is correct ans

They are asking about coefficient of linear expension , which is Alpha ….so B answer is correct .

why admin has not confirmed the answer.

I think B is right

B is the right answer.

@=◇L/L◇T

Coefficient of linear thermal expansion = change in length per original length per degree rise in temperature.

The right answer of coefficient of linear expansion is b option cuz they are asking about that coefficient is equal to

“B” IS CORRECT ANSWER;

Linear Expansion = Change in Length / (Original Length) (Change in Temperature)

Option A is 100% wrong

Option B is right

correct option is B

B is the right option.

Ais the standard form equation that shows the relation

Option (b) is right answer

Coefficient of linear thermal expansion (Alfa)=∆L/L∆T

B is the right answer
