A uniform-density disk of mass 14 kg, thickness 0.03 m, and radius 0.8 m makes one complete rotation every 0.7 s. What is the rotational kinetic energy of the disk?
What is the rotational angular momentum of the disk?
(Express your answer for rotational angular momentum in vector form.)Lrot = ??kg · m2/sKrot = ??  J

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

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.
