Answer:
Moment of inertia of the flywheel,
Explanation:
Given that,
The maximum energy stored on flywheel,
Angular velocity of the flywheel,
We need to find the moment of inertia of the flywheel. The energy of a flywheel in rotational kinematics is given by :
I is the moment of inertia of the flywheel
On rearranging we get :
So, the moment of inertia of the flywheel is . Hence, this is the required solution.
It can either get brighter or even larger depends on the options given also
Answer:
A light year is the distance light travels in a year. ... And an astronomical unit is the average distance between the earth and the sun. So the distance to the sun is by definition one AU. A parsec is the distance at which one astronomical unit subtends an angle of one second of arc.
