Potential energy is the an objects energy that is currently not being used but can be used. Example: A ball at the top of a hill is full of potential energy, and as soon as it begins rolling that becomes kinetic energy because it is in use. (Hard to explain but I hope this helps.)
The result of the Sun's light being refracted when it is
high in the sky around noon is blue, indigo and violet are strongly bent that
mostly skim through the upper atmosphere making the sky appear blue. The
refraction of the light during noon makes the sky blue.
Answer: 15.6 metres
Explanation:
Given that:
length of wave (λ)= ?
Frequency of wave F = 28 Hertz
Speed of wave (V) = 437 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply V = F λ
Make λ the subject formula
λ = V / F
λ = 437 m/s / 28 Hertz
λ = 15.6 m
Thus, the length of the wave is 15.6 metres
A) Water freezing
This is called the process of turning water as a liquid to its solid form which is ice.
Ice is almost together as one unlike liquid. This is why the molecules are more orderly.
The process of freezing is exothermic which means the heat has to be removed in the process.
Answer:
Creating a police department
Explanation:
Well through process of elimination, I doubt a local government has authority over the military, economy, or relationships with countries.
