The answer to your question is a 25.6 HZ
Answer:6.298,4.1,1.9015
Explanation:
Wavelength=![\frac{velocity of sound }{frequency}](https://tex.z-dn.net/?f=%5Cfrac%7Bvelocity%20of%20sound%20%7D%7Bfrequency%7D)
=
=4.397 m
Distance of 3rd speaker from speaker A is x
From B 78-x
Difference between the distances must be a whole number of wavelengths
First
for 1 st wavelength
2x=8.2+4.397=12.597
x=6.298m
second
For zero wavelength
![x-\left ( 8.2-x\right )=0](https://tex.z-dn.net/?f=x-%5Cleft%20%28%208.2-x%5Cright%20%29%3D0)
2x=8.2
x=4.1m
Third
![\left ( 8.2-x\right )-x=4.397](https://tex.z-dn.net/?f=%5Cleft%20%28%208.2-x%5Cright%20%29-x%3D4.397)
x=1.9015 m
Humid air has higher pressure because of the heaviness of the water
Answer:
1➡️ this is the method of decomposition
2➡️ H2 and O2
3➡️ b
sorry if I am wrong
