A 100 kg skier, including equipment, stands at the top of a black diamond ski run. The gravitational potential energy of the skier relative to the bottom of the ski run is 200 kJ. What is the vertical distance to the bottom of the run? Been trying to figure this out for hours. I still don't understand please help

you cant move and you feel like someones pushing you down onto your bed it can feel like you want to get up but you just can't it can be extremely scary

conduction, convection, radiation

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.
