An astronaut jumps with a particular initial velocity on Earth and measures a maximum height of 0.936 m and a range of 1.72 m. Later, he jumps on a new planet where the acceleration due to gravity is one third of its value on Earth. (a) If he jumps with the same initial velocity (speed and angle) what will his new maximum height b

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.
