<span>Commutator
is the moving part of the electric motor and periodically reverses the current
direction between the rotor and the external circuit.One end of the coil is
attached to each half of the commutator.
Commutator are used so when electricity flows through the circuit, the
coil will rotate continually in the same direction.</span>
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:
More than two million electron volts.
Explanation:
More than two million electron volts energy are needed to break or split a deuteron into a proton and a neutron. Nuclear binding energy is the type of energy that is required to split an atom's nucleus into protons and neutrons. The deuteron is an isotope of hydrogen that is composed of a proton and a neutron and it is a stable particle. Very huge amount of energy is needed for the splitting of nucleus due to the presence of heavy particles i.e. proton and neutron.
I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.
<h3 /><h3>What is density?</h3>
Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
I study if the volume or density of items determines whether solid objects float or sink in water in this scientific inquiry I did the experiment of density, mass, and volume using a rock and a standard-shaped piece of wood.
It is critical that the chosen piece of wood is larger than the rock and that the rock be tiny enough to fit inside the measuring cylinder. I see both the rock and a chunk of wood.
Hence I formulate a hypothesis based on their observations about what occurs when both the rock and the wood are submerged in water.

1000 miles = 1610km = 1.61x10^6m
2 weeks = 14 days = 14x24x1440
V=d/t = 1.61x10^6/14x24x1440
= 3.33m/s
