<span>Ni = 5
The Rydberg formula for hydrogen is
1/w = R(1/a^2 - 1/b^2)
where
w = wavelength in vacuum
R = Rydberg constant 1.0973731568508x10^7 1/m
a,b = integers greater than or equal to 1 and a < b
Now we need to select the value for a.
a = 1 will converge towards 91.13 nm
a = 2 converges towards 364.51 nm
a = 3 converges towards 820.14 nm
...
Because of this, we will assume a = 1 for this problem since it converges closest to the wavelength given.
Substitute known values
1/w = R(1/a^2 - 1/b^2)
1/9.504x10^-8 = 1.0973731568508x10^7(1/1^2 - 1/b^2)
10521885.52 = 1.0973731568508x10^7(1/1 - 1/b^2)
0.958824759 = 1 - 1/b^2
-0.041175241 = -1/b^2
0.041175241 = 1/b^2
24.28643927 = b^2
4.928127359 = b
So Ni = 5.</span>

Answer:
(B) Boreal owls range over larger areas in regions where food of the sort eaten by small mammals is sparse than they do in regions where such food is abundant
Explanation:
Living beings exhibit various changes in the behavior and niche to make themselves better fitted to the conditions of their habitats.
Boreal owls feed on the other smaller mammals such as mice and shrews. These organisms that serve as their prey are relatively less abundant in the habitat. To ensure the food availability, the boreal owls occupy a larger area so that they can catch their less abundant food organisms.
In the habitats where the prey species of boreal owls are present in a larger number, these owls occupy smaller regions since the food organisms are easily available.
