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):

low freq = 100 mhz

low wavelength =101.7m

length = 3x10^8/freq

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
