Answer with Explanation:
We are given that
Mass of person,M=80 kg
Radius,r=3.5 m
Moment of inertia of merry,I=
Angular velocity of platform=
1.Law of conservation of angular momentum
Where
Substitute the values
Angular velocity when the person reaches the edge =0.418 rad/s
2.Rotational kinetic energy of the system before the person's walk
3.Rotational kinetic energy of the system after the person's walk
<span>So we wan't to know what happens during nuclear fusion where we have 12 atoms. Nuclear fusion is a nuclear process where 2 or more nuclei will form 1 or more different nuclei with a release of energy. So if we start with 12 atoms, the most likely result will be 6 atoms. </span>
