A source of sound vibrates with constant frequency. Rank the frequency of sound observed in the following cases from the highest to the lowest. If two frequencies are equal, show their equality in your ranking. All the motions mentioned have the same speed, 25 m/s. (Use only "" or "=" symbols. Do not include any parentheses around the letters or symbols.)

(a) The source and observer are stationary.
(b) The source is moving toward a stationary observer. (c) The source is moving away from a stationary observer. (d) The observer is moving toward a stationary source. (e) The observer is movin

a way from a stationary source.

anonymous · Answer

i got this b=d>a>c=e but its telling me that its incorrect

anonymous · Answer

I agree with your order, perhaps try switching b and d / c and e?
Highest        Lowest
d/b       a        c/e

anonymous · Answer

its still wrong

anonymous · Answer

i dont understand why though

anonymous · Answer

Hmm, are you putting this into an online form?

anonymous · Answer

yes

anonymous · Answer

they are a pain.. I am a physics teacher and think you are correct. put them all in every combination then move on?!
