Aphoton has encrgy of 50 mev and is moving along the +a axis. another photon has energy of 200 mev and is moving along the -y axis (a) what is the total energy of the system? what is its total momentum? (b) if a single particle had the same energy and momentum, what would its mass be? what would its direction of travel and what would its spoed be?

tbh i dont know ether

a person with a mass of 106kg has a weight of 1060n

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

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.
