The coefficient of static friction between the block and the inclined plane is 0.4 and 0=25º. The block is placed on the inclined plane. The block will:
A not move
B. start moving down the incline and then stop before it reaches the bottom of the incline
C. start moving down the incline and continue to increase its velocity
D. start moving and increase its acceleration until it reaches the bottom of the incline
E. start moving and then its acceleration will decrease
F
3 kg
5 kg

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.
