Adisc of moment of inertia 1.8 k g. m2 is rotating at a constant angular velocity of 3.2 rad. s−1. a second disc of moment of inertia 0.6 kg. m2, initailly at rest, falls on the first disc and the two rotate as a system. what is the angular velocity of the system?

2.4 rad/s

Explanation:

= Initial angular velocity = 3.2 rad/s

= Final angular velocity of the system

= Initial angular momentum = 1.8 kgm²

= Final angular momentum = 0.6 kgm²

As there is no external torque then the angular momentum in the system is conserved

The angular velocity of the system is 2.4 rad/s

b.transmitters send radio waves, and receivers capture radio waves.
