Answer:
You will hear the note E₆
Explanation:
We know that:
Your speed = 88m/s
Original frequency = 1,046 Hz
Sound speed = 340 m/s
The Doppler effect says that:
Where:
f = original frequency
f' = new frequency
v = velocity of the sound wave
v0 = your velocity
vs = velocity of the source, in this case, the source is the diva, we assume that she does not move, so vs = 0.
Replacing the values that we know in the equation we have:
This frequency is close to the note E₆ (1,318.5 Hz)
Answer :Scientific Definition of Inference
In science, there are a few different types of inferences, but in general an inference is: “An educated guess made through observation.” You might use these inferences to share a potential reason why something happens or how it happens.
Explanation:
Answer:
The <u>nucleus</u> is the core of an atom.
Step-by-step explanation:
That's just how it is.
IF voltage remains constant, then current is
inversely proportional to resistance.
The correct response is "b).", signifying "false" as the choice.
