2. An electron is in a position in an electric field which has an electric potential of 12V. a. How much electric potential energy does the electron have?
b. If the electron is allowed to move to a position where the potential is 4V, find the
change in potential energy.
c. If the mass of the electron is 9.1x10-31 kg, and it starts from rest, find the velocity of
the electron after moving through the potential difference

answer: i don't know the answer good luck

explanation:

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.
