Answer:
The wavelength of the visible line in the hydrogen spectrum is 434 nm.
Explanation:
It is given that, the wavelength of the visible line in the hydrogen spectrum that corresponds to n₂ = 5 in the Balmer equation.
For Balmer series, the wave number is given by :
R is the Rydberg's constant
For Balmer series, n₁ = 2. So,
or
So, the wavelength of the visible line in the hydrogen spectrum is 434 nm. Hence, this is the required solution.
Answer:
The problem occurs with all spherical mirrors.
Spherical mirrors are practical up to about inches in diameter.
Reflecting telescopes use spherical mirrors for apertures up to about 4 ".
Larger aperture telescopes use parabolic mirrors to obtain sharp focus.

Answer:
I think it has to do with Newtonian Physics
The bottom person will carry most of the weight because of the direction of the forces involved.
The strong one should be in the back to support the log the most if it is at an angle. The weaker person should be in the front to lift the log up and carry it, but not necessarily put in the same sort of strength. The person who is pushing it up will have a harder time than the person lifting it to make it easier to transport.
