The correct choice is C .
Technically, choice-A is the process involved. But it's already been done,
and widely published, and the spectrum of every element is easily available.
For you to take the time and go to the trouble of constructing the spectra
would be like inventing wheels if you want to ride a bicycle.

Answer:a
Explanation:
Given
![[H^+]=5.3\times 10^{-4}\ M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D5.3%5Ctimes%2010%5E%7B-4%7D%5C%20M)
and 
Also ![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
therefore 


Thus 

and ![pOH=-\log [OH^{-}]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E%7B-%7D%5D)
![[OH]^{-1}=10^{-10.25}](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D10%5E%7B-10.25%7D)
![[OH]^{-1}=1.88\times 10^{-11}\ M](https://tex.z-dn.net/?f=%5BOH%5D%5E%7B-1%7D%3D1.88%5Ctimes%2010%5E%7B-11%7D%5C%20M)
As the pH is less than 7 therefore solution is acidic
The velocity of Satellite A is 2% greater than velocity of satellite B.
The given parameters;
- <em>Altitude of Satellite A = 500 km</em>
- <em>Altitude of Satellite B = 800 km</em>
The forces acting on the Satellites are given as follows;


Thus, the velocity of Satellite A is 2% greater than velocity of satellite B.

It's not the second one since color has nothing to do with force. Also the third one isn't a factor since buoyant forces is the upward force of caused by fluid that opposes the object entering the liquid. The acceleration of the object and the mass of an object and how rough the surface are the only two factors in all the options.
