Question 4 (1 point) The George Washington Bridge crosses the Hudson River between New York and New Jersey. The span of the steel bridge is about 1.90 km. What might be the difference in meters between the maximum span and minimum span over the course of a year, if the temperature can vary from a low of -(4.4x10"'0]C in winter to a high of 42C in summer? Expansion coefficient of steel is or = 12.0 X 106 K'l. Use two significant figures in your answer. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: x10 C]
