Answer:240 rotations
Step-by-step explanation: 1 rotation/45 seconds * 60 seconds / minute * 60 minutes / hour * 3 hours = 3600*3/45 = 240 rotations
The solution to the problem is as follows:
Then, it's just...
L = Iω where...
ω = angular velocity
I = moment of inertia
So...
L = ML²/12 * ω
I hope my answer has come to your help. God bless and have a nice day ahead!
