Abattery-operated car utilizes a 12.0 v system. initially, the car is at rest at the base of a 163 m high hill. some time later, the 690 kg car reaches the top of the hill with a speed of 25.0 m/s. how much charge did the batteries move through the motor to accomplish this, neglecting friction? note that a battery provides energy by moving charge through the battery voltage, which is 12 v in this case. (hint: the car clearly gains kinetic energy and gravitational potential energy, so that energy most be coming from somewhere. what object in this problem is the original source of that energy? )

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.

the components of a vector are the parts of the vectors that are to each other.
