It depends on A) how fast the wire vibrates because sound is produced by vibration
Yeah, like a stop sign. We know it is most likely a stop sign since it has 8 sides or is an octagon.
I hope I helped!
Peak voltage is 2
period is 40ms
frequency = 1/period = 25Hz

Frequency is the vibration of noise and the vibration determines the pitch, which we depend on to be a pitch or frequency we can hear. If it's too high or too low our ears can't hear it
