Answer:
L= 0.059 mH
Explanation:
Given that
R = 855 Ω and C = 6.25 μF
V= 84 V
Frequency
ω = 51900 1/s
We know that
L=Inductance
C=Capacitance
ω =angular Frequency
ω² L C =1
(51900)² x L x 6.25 x 10⁻⁶ = 1
L= 5.99 x 10⁻⁵ H
L= 0.059 mH
Answer:
Multiple answers:
1. Power output P=17.59W
2.Intensity 160m I=17.6W/
3. dB = 77.3
4. f=178.5 Hz
Explanation:
First one comes from the expression
where<em> I </em>is the intensity, <em>P </em>is the power and <em>r </em>is the radio of the spherical wave, or in this case, the distance <em>x</em>. I solved for the Power by multiplying Intensity with the area (4
Second one is done with:
Solving for Intensity 2, the result mentioned.
The third is simply computed with
And finally the last one is done with doppler effect, taking into account the speed of the air as in 10ºC 337m/s.
Where <em>Finitial</em> is the frequency emitted and <em>s</em> is the speed of the sound. The wind blowing in positive is, in principle, going away of the observer.
