When an electric current flows through a wire, the current produces

a motor

a generator

mechanical energy

a magnetic field

this should be really simple

a person with a mass of 106kg has a weight of 1060n

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.
