Electrons orbit around the nucleus.
When a wave and/or the observer are moving, the frequency changes according to the Doppler Effect.
When the source is at rest and the observer moves away from it, the wave looks slower and its velocity will be:
v' = vsound - vobserver
In this case,
f₁ = v'/λ = (vsound - vobserver) / λ = f₀ · (<span>vsound - vobserver) / vsound
= f</span>₀ · (1 - vobserver/vsound)
On the contrary, when the source is moving away from an observer at rest, the wave appears with a different wavelengh:
λ' = (vsound + vsource) / f₀
In this case,
f₂ = v/<span>λ' = vsound / ((vsound + vsource) / f₀)
= </span>f₀ ·
Now, let's put together these two cases:
f' = v' / <span>λ' =
= </span>
<span>
= f</span>₀ ·
= f<span>₀ · </span>
<span>The next step of the scientific method is to analyze the results and draw conclusions. After that step, if the results agree with the hypothesis, then the results should be communicated. If the results do not support the original hypothesis, then the biologist must go back to the beginning and reformulate their hypothesis based on the results of the experiment.</span>
Hey there,
Your question states: What factors affect the speed of water waves
Let's get one thing out the way, (wavelength) does
affect the the speed of water. If anything, it would be how high the wavelength's are. The higher the wavelengths are, the more that it would affect the speed, because there very high, but if it were to go longer on the width side, that would increase the speed, but that's not the case. Your correct answer would be (higher wavelength).
Hope this really helps you.
Answer:
a) 3.210J/K
b) -3.073J/K
