An aluminum wing on a plane is 34.8 m long when the temperature is 20 oC. At what temperature would the wing be 0.06 m shorter? Enter your answer to one decimal place and do not enter units for this problem. You should think about the physics of the situation before trying to solve the problem. (Hint: You are being asked for a temperature, not a temperature change).
