Answer:
Hey
It would have to be C because no net energy is lost.
Answer:
![d=1.29*10^{-6}m](https://tex.z-dn.net/?f=d%3D1.29%2A10%5E%7B-6%7Dm)
Explanation:
From the question we are told that:
Distance of wall from CD ![D=1.4](https://tex.z-dn.net/?f=D%3D1.4)
Second bright fringe ![y_2= 0.803 m](https://tex.z-dn.net/?f=y_2%3D%200.803%20m)
Let
Strontium vapor laser has a wavelength \lambda= 431 nm=>431 *10^{-9}m
Generally the equation for Interference is mathematically given by
![y=frac{n*\lambda*D}{d}](https://tex.z-dn.net/?f=y%3Dfrac%7Bn%2A%5Clambda%2AD%7D%7Bd%7D)
Where
![d=\frac{n*\lambda*D}{y}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7Bn%2A%5Clambda%2AD%7D%7By%7D)
![d=\frac{2*431 *10^{-9}m*1.4}{0.803}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B2%2A431%20%2A10%5E%7B-9%7Dm%2A1.4%7D%7B0.803%7D)
![d=1.29*10^{-6}m](https://tex.z-dn.net/?f=d%3D1.29%2A10%5E%7B-6%7Dm)
The volume of water will increase . If yu subtract the original volume from the new volume of water you will get the volume of the small ball.
26.2/3.4 would be the average velocity for the run.
7.7 miles/hr
