1. A baseball pitcher throws a fastball at a speed of 50.0 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it through an almost straight-line distance of 4.2 m. Calculate the acceleration,
assuming it is uniform. Compare this acceleration to the acceleration due to gravity, 9.8 m/s?

the answer is b ) square root of 5

need to see circuit to get time constant

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.
