Answer:
10.7 m
Step-by-step explanation:
Given that,
The speed of a sound wave, v = 6,420 m/s
The frequency of the wave, f = 600 Hz
We need to find the wavelength of the wave. We can find it using the below relation as follows :
![v=f\lambda\\\\\lambda=\dfrac{v}{f}\\\\\lambda=\dfrac{6420}{600}\\\\\lambda=10.7\ m](https://tex.z-dn.net/?f=v%3Df%5Clambda%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7Bv%7D%7Bf%7D%5C%5C%5C%5C%5Clambda%3D%5Cdfrac%7B6420%7D%7B600%7D%5C%5C%5C%5C%5Clambda%3D10.7%5C%20m)
So, the wavelength of the sound wave is equal to 10.7 m.
Answer:
what
Step-by-step explanation:
Answer: 94.5
Step-by-step explanation:
9/2 × 21/4
Get common denominator
9 × 2 =18
2 × 2 = 4
18/4 × 21/4
21 × 18 = 378
378/4 = 94.5
