A proton is accelerated from rest through 2.0 kV. It then enters a uniform magnetic field of 0.30 T that is oriented perpendicular to its direction of motion. Required:
a. What is the radius of the path the proton follows in the magnetic field?
b. How long does it take the proton to make one complete circle in the magnetic field?

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.
