a position versus time graph is shown below.
a position versus time graph is shown with y-axis labeled position in meters north up to 20 and x-axis labeled time in seconds up to 10. a line connects points 0, 0 and 1, 4. a horizontal line connects points 1, 4 and 4, 4. a line connects points 4, 4 and 6, 10. a horizontal line connects points 6, 10 and 8, 10. a line connects 8, 10 and 9, 14, and then 10, 15.
use the graph to determine the instantaneous velocity in m/s of the object at 7.0 seconds?
0 m/s
1.4 m/s
7 m/s
10 m/s

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."

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.
