A) the universe is expanding
Every galaxy is moving away from each other - not just us. And the further they are away, the faster they are moving
Answer:
The maximum power density in the reactor is 37.562 KW/L.
Explanation:
Given that,
Height = 10 ft = 3.048 m
Diameter = 10 ft = 3.048 m
Flux = 1.5
Power = 835 MW
We need to calculate the volume of cylinder
Using formula of volume
![V =\pi r^2 h](https://tex.z-dn.net/?f=V%20%3D%5Cpi%20r%5E2%20h)
Put the value into the formula
![V=\pi\times(1.524)^2\times 3.048](https://tex.z-dn.net/?f=V%3D%5Cpi%5Ctimes%281.524%29%5E2%5Ctimes%203.048)
![V = 22.23\times10^{3}\ Liter](https://tex.z-dn.net/?f=V%20%3D%2022.23%5Ctimes10%5E%7B3%7D%5C%20Liter)
We need to calculate the maximum power density in the reactor
Using formula of power density
![P=\dfrac{E}{V}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7BE%7D%7BV%7D)
Where, P = power density
E = energy
V = volume
Put the value into the formula
![P=\dfrac{835\times10^{6}}{22.23\times10^{3}}](https://tex.z-dn.net/?f=P%3D%5Cdfrac%7B835%5Ctimes10%5E%7B6%7D%7D%7B22.23%5Ctimes10%5E%7B3%7D%7D)
![P=37561.85 = 37.562\times KW/L](https://tex.z-dn.net/?f=P%3D37561.85%20%3D%2037.562%5Ctimes%20KW%2FL)
Hence, The maximum power density in the reactor is 37.562 KW/L.

I am assuming you know the relation obtained between slit width, distance of screen from slits, distance of interference pattern obtained on the screen from the center and the wavelength of monochromatic light used in Young's Double Slit experiment.
λ =
![\frac{y*d}{D} = \frac{3.55*10^{-3}*1.25*10^{-4} }{2.25} = 1.97*10^{-7} m](https://tex.z-dn.net/?f=%20%5Cfrac%7By%2Ad%7D%7BD%7D%20%3D%20%20%5Cfrac%7B3.55%2A10%5E%7B-3%7D%2A1.25%2A10%5E%7B-4%7D%20%20%7D%7B2.25%7D%20%3D%201.97%2A10%5E%7B-7%7D%20m)
