Suppose that a steel bridge,1000 m long,was built without any expansion joints and that only one end of the bridge was held fixed.What would the difference in the length of the bridge be between winter and summer,taking a typical winter temperature as 0.00°C,and a typical summer temperature as 40°C? The coefficient of thermal expansion of steel is 10.5 × 10^-6 K^-1. A)0.42 m B)0.11 mm C)0.11 m D)0.42 mm E)0.37 cm

The change in length can be calculated using the formula: ΔL = L₀ * α * ΔT, where L₀ is the original length, α is the coefficient of thermal expansion, and ΔT is the change in temperature. Substituting the given values: ΔL = 1000 m * 10.5 × 10⁻⁶ K⁻¹ * 40 K = 0.42 m.
