Answer:
<em>The lighten travels 0.853 miles.</em>
Explanation:
Sound: Sound is a form of wave which is conveyed through an elastic medium from a vibrating body to a listener.
v = 2x/t .......................................... Equation 1
making x the subject of the equation
x = vt/2........................................ Equation 2
Where v = velocity of sound in air, x = distance traveled by the sound, t = time
Given: v = 344 m/s t = 8 s
Substituting into equation 2
x = 344(8)/2
x = 1376 m.
x = 1376×0.00062 miles = 0.853 miles
<em>Thus the lighten travels 0.853 miles.</em>
The radio waves have a very low frequency so they will always have a very low energy.
Good luck :)
E concave mirror because it reflects the light
Answer:
The epithelial cell shape and stratification are related to its function. For example, the skin is specialized to act as a "physical" barrier to the outside world. This barrier is both structural (multi-layered) and chemical in nature. Another example is the cells that make up the tubular elements of the kidney.

Explanation:
Heat energy
Solar energy
Electrical energy
Energy is the ability to do work. There are different forms of energy and they can be converted from one form to the other.
Heat energy is due to the changes in temperature of a body. When a body is heated, the electrons excite and gives off radiant energy which are visible to human eye. We often see red light when a body is heated.
Solar energy can be absorbed by organisms to produce light. Such an example is bioluminescence in some organisms. During the day, they trap solar energy that they glow with at night.
Electrical energy can also be used to produce light. We often see this in lightning and electrical bulbs in a circuit.
