MATIIZ Useu A steel railroad rail expands and contracts according to the formula A = alAT, where A/ is the change in length, a is a constant called the coefficient of linear expansion, / is the original length, and AT is the change in temperature. If a 50.0 ft steel rail is installed at 0°F, how many inches will it expand when the temperature rises to 190°F? (a = 6.5 x 10 /OF. Use the rules for working with measurements to give your answer to the appropriate accuracy and/or precision. Use the Metric and U.S. Conversion table to find the conversion factor(s).) in 10:59
