Answer:
circle
Explanation:
because Earth is not oblong
Explanation:
It is known that wave intensity is the power to area ratio.
Mathematically, I =
As it is given that power is 28.0 W and area is .
Therefore, sound intensity will be calculated as follows.
I =
=
=
or, =
Thus, we can conclude that sound intensity at the position of the microphone is .
An ammeter should be connected in series with the resistor to measure the current through it. If it is connected in parallel, its low resistance would cause a short circuit.
A voltmeter should be connected in parallel with the resistor to measure the voltage across it. If connected in series, its high resistance would cause no current to flow and thus it would show a very small or no reading.
