Answer:
The independent variable here is the types of soil
Explanation:
An independent variable is the variable that is not affected by the outcome of other variables in a given experiment. This variable is the variable that is intentionally altered/changed (directly or indirectly) by the researcher in order/expected to produce a result for the experiment. Thus, the independent variable here is the types of soil. This is because the soil was intentionally changed/varied by the researcher and it's expected to determine the heights of the bean plants grown.
Every line in the hydrogen spectrum that was in the visible light area had a relationship to a single number, which caught Balmer's attention. Its numeric value was 364.50682 nm. Any number more than 2 may be squared, divided by itself squared minus 4, and then multiplied by 364.50682 to obtain the wavelength of another line in the hydrogen spectrum (see the equation below). His formula predicted lines that were later discovered but had not yet been detected, allowing him to demonstrate that certain measurements of lines performed in his era using spectroscopy were somewhat off. He also turned out to be the series' capstone in terms of number.
The Balmer equation was first stated as follows (apart from a notation adjustment to provide Balmer's constant as B), and it could be used to determine the wavelength of the absorption/emission lines:

Where

B is a constant with the value of 
m is equal to 2
n is an integer such that

What is the atomic energy level?
- The set distances from an atom's nucleus where electrons may be found are referred to as energy levels (also known as electron shells).
- In an atom, the small, positively charged nucleus is surrounded by smaller, negatively charged electrons.
- Energy levels resemble the rungs of a ladder in several ways.
So the more about atomic energy level visit.

There are 150 neutrons in Uranium-242
I would say yes because science be getting deep
