a cars horn produces a constant frequency of 350 hz as it passes by suzy. what is the best estimate of the frequency suzy hears after the car passes her?\n330 hz\n350 hz\n360 hz\n700 hz
Answer
Explanation:
Step1: Recall Doppler - effect concept
When a source (car's horn) moves away from an observer (Suzy), the observed frequency is lower than the source frequency.
Step2: Analyze given options
The source frequency is 350 Hz. Since the car is moving away, the observed frequency must be less than 350 Hz. Among the options, 330 Hz is the only frequency less than 350 Hz.
Answer:
A. 330 Hz
