You hear three beats per second when two sound tones are generated. The frequency of one tone is known to be 610 Hz. The frequen
1 answer:
Answer:
F. Either B or C
Explanation:
The beat frequency is the difference of two frequencies of two waves.
Here, one wave has frequency 610 Hz and the beat frequency is 3 beats per second.
It is not mentioned which has a higher frequency. So, there are two possiblities.
or
Hence, the frequency of the other wave is 613 or 607.

- The amplitude A of a simple harmonic motion is the maximum displacement of the system with respect to the equilibrium position
- The period T is the time the system takes to complete one oscillation
During a full time period T, the mass on the spring oscillates back and forth, returning to its original position. This means that the total distance covered by the mass during a period T is 4 times the amplitude (4A), because the amplitude is just half the distance between the maximum and the minimum position, and during a time period the mass goes from the maximum to the minimum, and then back to the maximum.
So, the time t that the mass takes to move through a distance of 2 A can be found by using the proportion
and solving for t we find
b. 1.25T
Now we want to know the time t that the mass takes to move through a total distance of 5 A. SInce we know that
- the mass takes a time of 1 T to cover a distance of 4A
we can set the following proportion:
And by solving for t, we find
