The oxygen molecule, o2, has a total mass of 5.30×10-26 kg and a rotational inertia of 1.94×10-46 kg-m2 about an axis perpendicular to the center of the line joining the atoms. suppose that such a molecule in a gas has a speed of 1.49×103 m/s and that its rotational kinetic energy is two-thirds (2/3) of its translational kinetic energy.
what then is the molecule's angular speed aboutthe center of mass. (rad/s)

Explanation:

The translational kinetic energy depends on the mass and speed of the body, as follows:

While rotational kinetic energy depends on the moment of inertia and the angular velocity of the body, as follows:

. We know that:

Replacing (1) in (2):

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

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.
