QUESTION 6 A. At a concert, a person is standing 2.00 m from a speaker, where the sound intensity is 0.120 W/m2. Another person is 32.0 m from the speaker. Assume the sound is emitted equally in all directions. 10 = 1.00 x 10-12 W/m2 a) What is the intensity in W/m2 at 32.0 m from the speaker? b) What is the sound level in dB at 32.0 m from the speaker? "The intensity is 7.50 x 10-3 W/m2 The...
You stand 30 m from a large speaker at a concert, and the intensity of the sound you hear from that speaker is 4×10−2 W/m2 . How much power is the speaker emitting? What is the intensity of the sound from the speaker at a distance of 60 m ? The pain threshold for humans is a sound intensity level of about 120dB. At what distance from this speaker would the sound be painful?
At a concert, a person is standing 2.00 m from a speaker, where the sound intensity is 0.120 W/m2. Another person is 32.0 m from the speaker. Assume the sound is emitted equally in all directions. I0 = 1.00 x 10-12 W/m2 a) What is the intensity in W/m2 at 32.0 m from the speaker? b) What is the sound level in dB at 32.0 m from the speaker? A. The intensity is 7.50 x 10-3 W/m2 B. The intensity...

Two identical loudspeakers are some distance apart. A person stands 5.80 m from one speaker and 3.10 m from the other. What is the lowest frequency at which the person will hear destructive interference? The speed of sound in air is 340 m/s.
A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the wavelength of the first (n=1) interference maximum (constructive & destructive)? A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the wavelength of the first (n=1) interference maximum (constructive)? Speed of sound 343 m/s) (Unit m) Enter
A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the frequency of the second (n=2) interference minimum (destructive)? • I have asked this question before and for 428.75 Hz as an answer, which is telling me is an incorrect answer, I am unaware how to get the actual answer A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the frequency of the second (n...
I can’t figure out how to solve this. A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker. What is the wavelength of the first (n-0) interference minimum (destructive)? (Speed of sound 343 m/s) (Unit m)
