Hey pls don’t. Report my answer I’m in a test and I rlly want someone to answer my question
Answer:
golf
Explanation:
it's less physical strength in more of you hitting the ball with whatever the stick is called
<u><em>Answer:</em></u>
The ability of a substance to dissolve into another, called the solvent.
<u><em>Explanation:</em></u>
That is why water is called <u><em>"the universal solvent."</em></u>
Because it can dissolve almost anything.
The speed and temperature have nothing to do with solubility.
Answer:
2.11 m
Explanation:
<u>Given data</u>
h=6.626×
(plank constant)
L=45.7 pm
n=n2-n1
n=5-1
n=4
<em>where,</em>
<em>n2=5</em>
<em>n1=1</em>
<u>To find:</u>
E=?
λ=? (Wavelength)
<u>solution</u>
The energy stored in an electron at a specified level is given by;
E=
×
÷8m
..........(1)
<em>m=mass of electron(9.1×</em>
)
<em>l=length of box</em>
<u>To find E</u>
putting the value of given data in eq(1)
E=9.41×
<u>To find λ</u>
λ=hc/E............................(2)
c=3×
(speed of light)
putting the value in eq 2 to find wavelength
λ=2.11 m
<u></u>
<u>Note:</u>
There is a chance in calculation error. but the method is correct to solve the problem.
The electrical charge of particles. The total number of electrons in an atom is always the same as the number of protons in the nucleus. This means atoms have no overall electric charge. The number of protons in an atom is called its atomic hater number.
