Answer:
Explanation:
Two charged particles will vary in energy as we alter the distance between them.
1. Frequency: 
The frequency of a light wave is given by:
where
is the speed of light
is the wavelength of the wave
In this problem, we have light with wavelength
Substituting into the equation, we find the frequency:
2. Period: 
The period of a wave is equal to the reciprocal of the frequency:
The frequency of this light wave is (found in the previous exercise), so the period is:
The part of a river that would have animals with muscular bodies and adaptations that let survive in turbulent water is in the transition zone, the mid-transition zone to be precise.
Water at the source zone possesses a lot of potential energy and as it flows from the upper reaches the potential energy is turned into kinetic energy when the course of the river begins to gradually level out and this translates into increase in velocity. By the time river water reaches the middle of the transition zone, most of the potential energy would have been turned into kinetic energy and thus water velocity would be quite high here.
Animals living here would develop muscles because of constantly fighting against the strong current to avoid being swept downstream.
You should slow your pwc to "slow, no wake speed" when within 100 feet of anchored vessels or non-motorized craft.
<h3>What is Slow-no-wake?</h3>
This is the process of operating a personal watercraft at the slowest possible speed.
This helps to maintain steerage which prevents different forms of accident or risks when in motion in the water.
