Answer:
147.5 million km
Explanation:
The Sun is at an average distance of about 93,000,000 miles (150 million kilometers) away from Earth. It is so far away that light from the Sun, traveling at a speed of 186,000 miles (300,000 kilometers) per second, takes about 8 minutes to reach us.

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>
This type of classification used to be used when classifying the protostome organisms.
In this type of organism, the oral cavity develops from the blastophore, the initial cavity in the gastrula, an early stage of the development of the embryo.
