Solve the given question:

Question: The initial length of a rod is (Lo). The length increases by 0.05%. To find the new length (L), you must multiply Lo by what? You want to figure out how much the length increased. To find this change in length Lo, you must multiply the initial length Lo by what? Use these ideas in the following problem: The length of a steel bar increases by 0.040 % when its temperature is increased from 0 degrees C to 35 degrees C.

Part A- Calculate the temperature coefficient of linear expansion for this bar.

I need expert help to solve the above question and round the answer to three significant figures.
