Have wavelengths that are longer than normal.
The child on a swing can be modeled as a simple pendulum. The period of a simple pendulum is given by
Coefficient of volume expansion is 8.1 ×10⁻⁴ C⁻¹.
<u>Explanation:</u>
The volume expansion of a liquid is given by ΔV,
ΔV = α V₀ ΔT
ΔT = change in temperature = 48.5° C
α = coefficient of volume expansion =?
V₀ = initial volume = 2.35 m³
We need to find α , by plugin the given values in the equation and by rearranging the equation as,
![\alpha=\frac{\Delta \mathrm{V}}{\mathrm{V}_{0} \Delta \mathrm{T}}=\frac{0.0920}{2.35 \times 48.5}=0.00081](https://tex.z-dn.net/?f=%5Calpha%3D%5Cfrac%7B%5CDelta%20%5Cmathrm%7BV%7D%7D%7B%5Cmathrm%7BV%7D_%7B0%7D%20%5CDelta%20%5Cmathrm%7BT%7D%7D%3D%5Cfrac%7B0.0920%7D%7B2.35%20%5Ctimes%2048.5%7D%3D0.00081)
= 8.1 ×10⁻⁴ C⁻¹.
