To calculate the linear expansivity of a material, you can use the equation:
α = ΔL / (L * ΔT)
Where:
α is the linear expansivity coefficient,
ΔL is the change in length of the material,
L is the original length of the material,
ΔT is the change in temperature.
In this case, the original length (L) of the brass is given as 120 m, the change in length (ΔL) is 120.05 m - 120 m = 0.05 m, and the change in temperature (ΔT) is 100 °C.
Let's plug these values into the equation and calculate the linear expansivity coefficient (α):
α = 0.05 m / (120 m * 100 °C)
α = 0.05 m / 12000 °C
α ≈ 4.17 * 10^(-6) °C^(-1)
Therefore, the linear expansivity coefficient of the brass is approximately 4.17 * 10^(-6) per degree Celsius (°C).
