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 0.59 cm, connected to the balance staff by thin spokes of negligible mass. The total mass of the balance wheel is 0.85 gPart 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.

it becomes positively charged by charging it

true tan speed = ang vel x radius

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
