C) Organ system.
Your organs are working together to control and keep your body moving!! When a organ starts to do they're job it may need some other organs to help. When this happens it begins the Organ System!
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.
45° × π/180 = 0,7854 rad
ω = θ /t
ω = 0.7854 / 0.75 = 1.0472 rad/s
