A typical wall outlet voltage is 120 volts in the United States. Personal MP3 players require much smaller voltages, typically 235.0 mV. If the number of turns in the primary coil is 3575, calculate the number of turns on the secondary coil of the adapter transformer.

Number of turns in secondary will be 7

Explanation:

We have given primary voltage

Number of turns in the primary is

Secondary voltage is given

We have to find the number of turns in secondary

We know that

So

As the number of turns can not be in decimal so number of turns will be 7

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me
