: Write down an expression that you think models the average acceleration of the fan cart during the pulse as a function of the angle on the Angle Indicator. Justify using this model. Consider using limiting-case analysis in your justification.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

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.
