Type the correct answer in the box. round your answer to the nearest whole number.
calculate the mass of the ball using pe = m × g × h. (hint: rearrange the formula to solve for m.)
a ball held 2.0 meters above the floor has 59 joules of potential energy. the ball’s mass is about
kilograms.
(use g = 9.8 n/kg.)

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.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
