It’s my last question. what is the acceleration of the object in the graph?

-0.8 m/s²

Explanation:

All you need to do here is find the slope of that line. And since it's a line, it doesn't matter what two points you pick to do it; since the slope is the same throughout.

Slope = (y_2 - y_1)/(x_2 - x_1)

But in this case:

*Which is where the units for acceleration come from.

I chose the points (0,12) and (4,10) to get:

Acceleration = Slope = (4-12)/(10-0) = -8/10 = -0.8 m/s²

the answer is false

explanation:

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.
