    The answer to your question is 5.4 cm

    Explanation:

    This problem refers to calculate the change in length in one dimension due to a change in temperature.

    Data

    α = 12 x 10⁻⁶

    Lo = 150 meters

    ΔT = 30 °C

    Formula

    ΔL/Lo = αΔT

    solve for ΔL

    ΔL = αLoΔT

    Substitution

    ΔL = (12 x 10⁻⁶) (150) (30)

    Simplification

    ΔL = 0054 m = 5.4 cm
