Step-by-step explanation:
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 :
So, the wavelength of the sound wave is equal to 10.7 m.
32.5 square feet. If you do the area formula “A=5v13(13) over 2”
Answer:
1.the corresponding angles are propositional
2.the corresponding sides are proportional
