if the energy and amplitude are related. if you create a wave with a rope how will the amplitude change as you move you hand up and down faster how is the energy changing in the wave

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

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.
