A plug-in transformer supplies 9 V to a video game system. (a) How many turns are in its secondary coil, if its input voltage is 111 V and the primary coil has 340 turns? g

The number of turns in the secondary coil is 28.

Explanation:

Given that,

Input voltage given to the transformer,

Output voltage supplied to the video game,

Number of turns in the primary coil,

We need to find the number of turns in its secondary coil. We know that the transformer equation is given by :

or

So, the number of turns in the secondary coil is 28.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
