The disk spins at a constant number of revolutions per second. This means, the angular velocity is constant.

We know that,

Linear velocity = r x Angular Velocity
where r is the radius.

So, for a given angular velocity, larger value of r will have larger Linear velocity. Since the value of r at point B is more than at point A, the value of Linear velocity will be more at point B.

So, the correct answer is option C

Inessa05 [86]

Think about a really long, flat 3-dimensional object. This has a certain volume, and a certain (big) surface area because of its length. Now, make the 3-dimensional object fat and maintain the volume. Notice how you have minimized surface area but maintained volume. This is how I would go about solving it.

arlik [135]

Answer:

Median: 178

Range:34

Step-by-step explanation:

To find the median, order the numbers from least to greatest:

162, 169,174, 177, 178. , 187, 192, 194, 196

Now, find the number in the middle:

178

To find the range, you subtract the greatest number (162) from the biggest number (196).
