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.
<span>The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas</span>
Answer:Yes
Explanation:yeah i think it could be possible because the universe is so far and wide its probably infinite and if we did i personally believe that we would be absolutely be annihilated by them because we would be so far behind technology wise we would have no use for the\

Well, there isn't the most renewable source but there are sources that are renewable, like solar energy.
Boron, Aluminum, Gallium, Indium, Thallium
