Answer:
The sound intensity at the position of the microphone is 
Explanation
Sound intensity is given by the formula
Where 
is the sound intensity, 
is the power and 
is the area.
Since the loudspeaker radiates sound in all directions, we have a spherical sound wave where the radius r is the distance of the microphone from the speaker.
∴ is given by 
where 
is the radius
From the question, = 33.0W, = 52.0m
∴ 
Hence, the sound intensity at the position of the microphone is 9.71 × 10⁻⁴ W/m²
Answer:
Negative acceleration occurs when an object speeds up in the negative direction.
Positive acceleration occurs when an object speeds up in the positive direction.
Explanation:
This might be wrong but I get some points for a answer..
Answer: I am getting a result around the 54,800 area, so I am selecting the 55,000 HP answer.
Fish swimming forward in the water, the water gets pushed backward because the fish moving forward is forcing the water to move backward, the motion forward and backward are the same, they are opposite and equal.
