Answer:
Doppler Effect
Explanation:
Doppler Effect is a term in Physics that describes the phenomenon experienced when there is change in wave frequency during the relative motion between a wave source and its observer.
In other words, it is referred to as increase or decrease in the level of sound, or other waves as the distance between source and observer is closer or farther from each other, such that it causes change in pitch, which is noticeable by the observer.
For example, when a sound object moves towards an individual or observer, the frequency of the sound waves increases, leading to a higher pitch, and at the same time, when the sound object moves away from an individual or observer, the frequency of the sound waves decreases, leading to a lower pitch. E.g passing siren from ambulance.
Hence, in this case, the right answer is DOPPLER EFFECT

Answer:The problem that was better defined was that of shortening the amount of tme students wait in the lunch line.
Explanation:
The second problem was not well defined because the school spirit can be increased in a vast number of ways which the class didn't mention any.
Therefore todefine the second problem, the class has to state a specified area in the which they want to tackle in other to incresa the spirit of the school just like the first class has specifically stated that it is the time student wait in lunch line they want to shorten.
A well defined problem will be more easier to solve than the one which is not defined.
C and D are likely correct.
High interest rates would likely dissuade people from using credit cards and would likely move them back to using their debit cards for purchases and to keep credit card purchases to ones that they knew they could pay back. You would end up getting people who were more desperate for the line of credit using it.
