A solution is a homogeneous mixture such as salt water
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:
The darts hit very different areas of the board.
Explanation:
Answer:
(a) 
(b) The force is repulsive
Explanation:
a) According to Coulomb's law, the magnitude of the electrice force that one particle exerts on the other is defined as:

Here k is the coulomb constant,
and
are the signed magnitudes of the charges and d is the distance between them.

b) According to Coulomb's law, if the two charges have the same sign, the electrostatic force between them is repulsive.
Answer:
Ensures land is used for its designated purposes hence avoiding misuse of land.
Explanation:
The process of urban planning ensures that different land uses are shown such as commercial, residential, public land, forestry and agricultural and institutional lands. This process helps in designing for essential services such as roads, sewarage and water, gas and electricity. In the process, encroachment is controlled and land utilized as planned. Therefore, land is properly utilized while minimizing environmental pollution, leading to sustainable development.
