The characteristics of the sound waves allow to find the result for the wavelength is:
λ = 34.29 m
The sound wave is a longitudinal traveling wave, where the speed of the wave depends on the air temperature.
v =
where v₀ is the speed of sound for T = 0ºc v₀ = 331 m / s.
indicate that the temperature is T = 20ºC, let's find the speed of the traveling wave.
v = 331
v = 342.9 m / s
The speed of sound is related to wavelength and frequency.
v = λ f
λ =
Let's calculate
λ = 34.29 m
In conclusion using the characteristics of sound waves we can find the result for the wavelength is:
λ = 34.29 m

Answer:
Capacitive Reactance is 4 times of resistance
Solution:
As per the question:
R =
where
R = resistance
f = fixed frequency
Now,
For a parallel plate capacitor, capacitance, C:
where
x = separation between the parallel plates
Thus
C ∝
Now, if the distance reduces to one-third:
Capacitance becomes 3 times of the initial capacitace, i.e., x' = 3x, then C' = 3C and hence Current, I becomes 3I.
Also,
Also,
Z ∝ I
Therefore,
Solving the above eqn:
