A CD rotates with an angular momentum of 20 Kg. m^2/s and moment of inertia 4 Kg. m^2. The angular velocity of this CD is equal to 24 rad/sec

5 rad/sec

80 rad/sec

16 rad/sec

answer: a. same unit

explanation:

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

continuous conducting path for current, power supply

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
