A certain alarm clock ticks four times each second, with each tick representing half a period. The balance wheel consists of a t

hin rim with radius 0.54 cm , connected to the balance staff by thin spokes of negligible mass. The total mass of the balance wheel is 0.95 g .Part AWhat is the moment of inertia of the balance wheel about its shaft?Express your answer using two significant figures.Part BWhat is the torsion constant of the hairspring?Express your answer using two significant figures.

A group of students collected the data shown below while attempting to measure the coefficient of static friction (of course, it

Ostrovityanka [3204]

Answer:

0.130

Explanation:

The coefficients of static friction recorded for each trial are listed as follows:

1. 0.053

2. 0.081

3. 0.118

4. 0.149

5. 0.180

6. 0.198

Adding these coefficients together results in: 0.053 + 0.081 + 0.118 + 0.149 + 0.180 + 0.198

= 0.779

Consequently;

the mean coefficient of static friction = $\frac{sum of coefficient of static friction}{number of trials}$

= $\frac{0.779}{6}$

= 0.12983

The mean coefficient of static friction is 0.130
