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

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
