What is the moment of inertia i of this assembly about the axis through which it is pivoted? Express the moment of inertia in terms of mr

The moment of inertia of the assembly is

Explanation:

Moment of inertia of a rod of mass M and length L about its center is given by

Substitute for M and 2x for L

Moment of inertia of mass , distance x from the axis:

Moment of inertia of mass , distance x from the axis:

The moment of inertia of each of the components is found out. Moment of inertia of point particle with mass MM is given by the product of its mass and the square of its distance from the axis

The total moment of inertia of the system is given by:

Substitute from to the above relation:

The moment of inertia of the assembly is

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.
