The number of hours of daylight, $\text{L}$, in Johnsville can be modeled by the function:

$$\text{L}=\cfrac{35}{3}+\cfrac{7}{3}\sin\left(\cfrac{2\pi}{365 }x\right)$$

...where $x$ is the number of days after March 21. Determine the difference in the number of hours of daylight on April 30 versus April 10.
