Answer:
0.507 m
Explanation:
L = Length of the golden gate bridge = 1300 m
α = Coefficient of linear expansion of steel = 13 x 10⁻⁶ °C⁻¹
T₀ = Lower temperature = 0 °C
T = Higher temperature = 30 °C
ΔL = Change in length of the golden gate bridge
Change in length of the golden gate bridge is given as
ΔL = L α (T - T₀)
ΔL = (1300) (13 x 10⁻⁶) (30 - 0)
ΔL = 0.507 m
