sorry I only knew a few of the answers, hope I still helped
Ideally, if all the magnetic of one winding cuts the other winding, and there isn't any loss in the transformer core or the resistance of the wire, then the voltage across each winding is proportional to the number of turns in its coil.
If you apply 100 V to a winding of 50 turns, then a winding that yields 20 volts
must be wound with
(20/100) of 50 turns = 10 turns
B. vibrate with the frequency of the received sound<span />
This means it doesn't change its velocity and it doesn't have momentum. 3. Examples of Newton's 1st Law If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It will also stop if it hits something, like a player's stick or a goalpost.
