Answer:
An electric chemical cell is not always needed to have a power circuit. But every other part is.
The <u>frequency</u> of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.
<h3>What is light?</h3>
Light can be defined as a form of electromagnetic waves that does not require any medium for its propagation. This ultimately implies that, light is a form of wave that is generally referred to as a visual signal because it can be seen with the eyes.
According to the model of light wave, the <u>frequency</u> of emitted light is directly proportional to the energy between the two orbits and this determines the color of the light.
<em>In conlcusion, the </em><u><em>frequency</em></u><em> of emitted </em><em>light</em><em> is highly dependent on the </em><em>energy</em><em> between the two (2) </em><em>orbits</em><em>.</em>

Answer
given,
conducting wire length = ℓ m = 0.5
moves at velocity = v m/s = v ( t ) = 4 t + 9
magnetic field strength = B = 2 T
V = − B ℓ v
V = - 2 × 0.5 × v
V = - v
a) 
b) given
v ( t ) = 4 t + 9
V = (-1)(4t + 9)
