Answer:

A) Because light is due to the electromagnetic fields (fields moving at the speed of light)

Note: Electrical energy is also used to describe the energy usage

in RLC circuits

The Bohr radius a0 is the most probable distance between the proton and the electron in the Hydrogen atom, when the Hydrogen ato
katen-ka-za [31]

Answer:

The electric force is  F =  11.9 *10^{-9} \ N

Explanation:

From the question we are told that

    The  Bohr radius at ground state is  a_o  =  0.529 A =  0.529 ^10^{-10} \ m

    The values of the distance between the proton and an electron  z =  2.63a_o

The electric force is mathematically represented as

     F  =  \frac{k * n  * p }{r^2}

Where n and p are charges on a single electron and on a single proton which is mathematically represented as

      n = p  =   1.60 * 10^{-19} \ C

    and  k is the coulomb's  constant with a value

           k =9*10^{9} \ kg\cdot m^3\cdot s^{-4}\cdot A^2.

substituting values

       F =  \frac{9*10^{9} *  [(1.60*10^{-19} ]^2)}{(2.63 * 0.529 * 10^{-10})^2}

         F =  11.9 *10^{-9} \ N

A parallel RLC resonant circuit has a resistance of 200 Ω. If it is known that the bandwidth is 80 rad/s and the lower half-powe
d1i1m1o1n [39]

Answer:

L= 3.6mH

C =9.9 microfarad

Explanation:

Resonant frequency fr

fr = fl + 1/2 BW

fr = 800+ 1/2×80

=800+40

=840 rad/s

Bandwidth (BW)

BW = fr/Q

Q = quality factor

Q= fr/ BW

Q = 840/80

Q= 10.5

Quality factor = R/Xl

Xl = inductive reactance

Xl = R/Q

Xl = 200/10.5

Xl = 19.05 ohms

Xl =2πfL

L= Inductance

L = Xl /2πf

L =19.05/5278.56

L= 3.6mH

Capacitor C

1= fr^2 × 4π^2LC

C = 1/fr^24π^2L

C = 1/100307.5

C= 9.9microfarad
