Answer:
The energy carried by an electromagnetic wave is proportional to the frequency of the wave. The wavelength and frequency of the wave are connected via the speed of light: Electromagnetic waves are split into different categories based on their frequency (or, equivalently, on their wavelength).

The missing question is: how long does the trip take?
First of all, we need to find the initial distance covered by Dylan. In the first part, he rides for

at a speed of
v = 15 mph
therefore, the distance he covered is

Then Dylan stopped for a time of

Finally, on the way back, Dylan covered again this distance but travelling at a new speed of
v = 10 mph
So, the time he took is

So, the total time of the trip was

Answer:
We can also prove the conservation of mechanical energy of a freely falling body by the work-energy theorem, which states that change in kinetic energy of a body is equal to work done on it. i.e. W=ΔK. And ΔE=ΔK+ΔU. Hence the mechanical energy of the body is conserved
Explanation:
Answer:
because it is from a mathematical combination of SI base units
