The uncertainty δp sets a lower bound on the average momentum of a particle in the nucleus. if a particle's average momentum were to fall below that point, then the uncertainty principle would be violated. since the uncertainty principle is a fundamental law of physics, this cannot happen. using δp=2.1×10−20 kilogram-meters per second as the minimum momentum of a particle in the nucleus, find the minimum kinetic energy kmin of the particle. use m=1.7×10−27 kilograms as the mass of the particle. note that since our calculations are so rough, this serves as the mass of a neutron or a proton.

the correct answer is a. 27

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.
