3.32µF and 1.64µF    

Since, you haven't actually asked a question, I am going to make a guess on what the question is based upon the data provided. My educated guess is "What are the values of the two capacitors?"    

The formula for the Capacitive reactance is  

X = 1/(2*pi*f*C)  

where  

X = reactance  

f = frequency  

C = capactance    

Let's solve for C  

X = 1/(2*pi*f*C)  

CX = 1/(2*pi*f)  

C = 1/(2*pi*f*X)    

Now with the capacitors in parallel, we have a reactance of:  

I = V/X  

IX = V  

X = V/I  

X = 12.3/0.56  

X = 21.96428571    

So the capacitance is:  

C = 1/(2*pi*f*X)  

C = 1/(2*pi*1460*21.96428571)  

C = 4.96307x10^-6 = 4.96307 µF    

And with the capacitors in series we have a reactance of:  

X = V/I  

X = 12.3/0.124  

X = 99.19354839    

So the capacitance is:  

C = 1/(2*pi*f*X)  

C = 1/(2*pi*1460*99.19354839)  

C = 1.09896x10^-6 = 1.09896 µF    

Now we can setup two equations with 2 unknowns.  

4.96307 = x + y  

1.09896 = 1/(1/x + 1/y)    

y = 4.96307 - x  

1.09896 = 1/(1/x + 1/(4.96307 - x))  

1.09896 = 1/((4.96307 - x)/(x(4.96307 - x)) + x/(x(4.96307 - x)))  

1.09896 = 1/(((4.96307 - x)+x)/(x(4.96307 - x)))  

1.09896 = 1/(4.96307/(x(4.96307 - x)))  

1.09896 = x(4.96307 - x)/4.96307  

5.45422 = x(4.96307 - x)  

5.45422 = 4.96307x - x^2  

0 = 4.96307x - x^2 - 5.45422  

0 = -x^2 + 4.96307x - 5.45422    

We now have a quadratic equation. Use the quadratic formula to solve, getting roots of 3.320460477 and 1.642609523. You may notice that those 2 values add up to 4.96307. This is not coincidence. Those are the values of the two capacitors in µF. Rounding to 3 significant figures gives us 3.32µF and 1.64µF.

Why do elements produce different numbers of spectral lines
frutty [35]

Explanation:

Elements can be differentiated on the basis of their spectral lines. As the spectra of any element is obtained when the electrons in the orbits of an atom change their states. When they move from lower to higher orbits they absorbs the radiation or energy. When the fall back from higher energy state to lower state they emit the radiations. Thats how the spectra of radiation is obtained. Now coming towards your question, as the different elements have different atomic numbers, they have different number of electrons in their shells. That's why the presence of the number of electrons in the shells of different elements vary. So the different number of electrons in different elements lead to the production of different numbers of spectral lines.

irina1246 [14]

Answer:

106.83

Explanation:

N = 332, l = 14 cm = 0.14 m, i = 0.88 A, B = 0.28 T

Let ur be the relative permeability

B = u0 x ur x n x i

0.28 = 4 x 3.14 x 10^-7 x ur x 332 x 0.88 / 0.14       ( n = N / l)

ur = 106.83
