What is a Scale?</h3>
This can be defined as a balance or any of various other instruments or devices for weighing.
The expression in terms of defined quantities and g, for the force that the scale under left pillar shows that Fu =((mg/2) +2 mp) g .

Explanation:
We need to calculate the speed of light in each materials
(I). Gallium phosphide,
The index of refraction of Gallium phosphide is 3.50
Using formula of speed of light
....(I)
Where,
= index of refraction
c = speed of light
Put the value into the formula
![v=\dfrac{3\times10^{8}}{3.50}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B3%5Ctimes10%5E%7B8%7D%7D%7B3.50%7D)
![v=8.6\times10^{7}\ m/s](https://tex.z-dn.net/?f=v%3D8.6%5Ctimes10%5E%7B7%7D%5C%20m%2Fs)
(II) Carbon disulfide,
The index of refraction of Gallium phosphide is 1.63
Put the value in the equation (I)
![v=\dfrac{3\times10^{8}}{1.63}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B3%5Ctimes10%5E%7B8%7D%7D%7B1.63%7D)
![v=1.8\times10^{8}\ m/s](https://tex.z-dn.net/?f=v%3D1.8%5Ctimes10%5E%7B8%7D%5C%20m%2Fs)
(III). Benzene,
The index of refraction of Gallium phosphide is 1.50
Put the value in the equation (I)
![v=\dfrac{3\times10^{8}}{1.50}](https://tex.z-dn.net/?f=v%3D%5Cdfrac%7B3%5Ctimes10%5E%7B8%7D%7D%7B1.50%7D)
![v=2\times10^{8}\ m/s](https://tex.z-dn.net/?f=v%3D2%5Ctimes10%5E%7B8%7D%5C%20m%2Fs)
Hence, This is the required solution.
Answer:
10
Explanation: Earth takes 24 hours to complete one spin, and Mars takes 25 hours. The gas giants rotate really fast. Jupiter takes just 10 hours to complete one rotation. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours.
