Physical .. More questions ..?
I need help to work these problems out … But I have answers for me that shows the work would be great! The Concorde is 62 m long when the temperature is 23 degrees C. In flight, the outer skin of the supersonic jet can reach 105 ยบ C due to friction air. The coefficient of linear expansion of the skin is 2.0 x 10 ^ -5 (degrees C) ^ -1. Find the number in which the Concorde expands. (Chapter 13)
Since the coefficient is given in units per degree Celsius (eg, C ^ -1 1 / C), you know you have to multiply that by degrees Celsius to remove the units (also that only makes sense). The following applies to the original length of an answer in meters. the change in length = length (original) * expansion coefficient * Change in temperature = m * 62 0.000020 / C * 82C = 62 m * 0.00164 = 0.10168 m Unfortunately, only two digits of precision. Therefore, if we be technical about it, I should say that the change in length is 0.10 meters. But you probably want the answer above.
