<h2>Relationship Between Frequency and Period</h2>
The frequency and the period are inversely proportional.
where T is the period
We're given:
- <em>v</em> = 340 m/s
- <em>f</em> = 1000 Hz
Because the frequency and the period are reciprocals of each other, we can find the period of the sound by finding the reciprocal of the frequency:
Answer: (-4.3, 2.5)
Explanation:
In the second quadrant, magnitude of the vector is 5 and angle is 30° from the negative x-axis.
We can write this in terms of its components:
Thus, the components of vector in the second quadrant are (-4.3, 2.5)
