A certain alarm clock ticks four times each second, with each tick representing half a period. The balance wheel consists of a thin rim with radius 0.58cm , connected to the balance staff by thin spokes of negligible mass. The total mass of the balance wheel is 0.85g .
Part A
What is the moment of inertia of the balance wheel about its shaft?
Express your answer using two significant figures.
Part B
What is the torsion constant of the hairspring?
Express your answer using two significant figures.
