1. The problem statement, all variables and given/known data A 61.00m long steel measuring tape is calibrated for use at 20.0∘C. How long is this tape under the following conditions: a hot day with 38∘C? Express your answer using four decimal places and include the appropriate units. i've been losing my mind over this, i swear i'm doing it correctly. 2. Relevant equations ΔL/L=αΔT 3. The attempt at a solution (38-20)=18°C (61m)(1.2*10-5)(18)= .01317m Mastering physics keeps telling me that I'm inncorrrect , I swear i'm doing it how the book wants me to do it.
