<span>The Halogen outer layer is considered to be full with eight electrons. Halogen is also considered to be part of the Noble gases classification. The exchange of electrons in the halogen atom renders a photon energy pulse with produces light. The consentrated light spectrum is produced in the halogen light bulbs and halogen laser products.</span>
Answer:
Human beings can see "visible" light.
Visible light is considered to be between 4000-7000 Angstroms or
400-700 millimicrons
1 Angstron = 1E-10 m
1 Millimicron = 10 Angstroms
Answer:
L=1.49 m
Explanation:
We are given that
![M=3.11 kg](https://tex.z-dn.net/?f=M%3D3.11%20kg)
![m_1=m_2=0.213 kg](https://tex.z-dn.net/?f=m_1%3Dm_2%3D0.213%20kg)
![I=0.831 kgm^2](https://tex.z-dn.net/?f=I%3D0.831%20kgm%5E2)
We have to find the length L of the rod
Moment of inertia of the system
![I=\frac{ML^2}{12}+\frac{mL^2}{4}+\frac{mL^2}{4}](https://tex.z-dn.net/?f=I%3D%5Cfrac%7BML%5E2%7D%7B12%7D%2B%5Cfrac%7BmL%5E2%7D%7B4%7D%2B%5Cfrac%7BmL%5E2%7D%7B4%7D)
![0.831=L^2(\frac{M}{12}+\frac{2m}{4})=L^2(\frac{3.11}{12}+\frac{0.213}{2})](https://tex.z-dn.net/?f=0.831%3DL%5E2%28%5Cfrac%7BM%7D%7B12%7D%2B%5Cfrac%7B2m%7D%7B4%7D%29%3DL%5E2%28%5Cfrac%7B3.11%7D%7B12%7D%2B%5Cfrac%7B0.213%7D%7B2%7D%29)
![(\frac{3.11+1.278}{12}L^2=0.831](https://tex.z-dn.net/?f=%28%5Cfrac%7B3.11%2B1.278%7D%7B12%7DL%5E2%3D0.831)
![L^2=\frac{0.813\times 12}{3.11+1.278}](https://tex.z-dn.net/?f=L%5E2%3D%5Cfrac%7B0.813%5Ctimes%2012%7D%7B3.11%2B1.278%7D)
![L=\sqrt{\frac{0.813\times 12}{3.11+1.278}}](https://tex.z-dn.net/?f=L%3D%5Csqrt%7B%5Cfrac%7B0.813%5Ctimes%2012%7D%7B3.11%2B1.278%7D%7D)
![L=1.49 m](https://tex.z-dn.net/?f=L%3D1.49%20m)
Hence, the length of rod=L=1.49 m
I believe the answer is A.
