An optical disk drive in your computer can spin a disk up to 10,000 rpm (about 1045 rad/s 1045 rad/s ). If a particular disk is spun at 968.7 rad/s 968.7 rad/s while it is being read, and then is allowed to come to rest over 0.234 seconds 0.234 seconds , what is the magnitude of the average angular acceleration of the disk?

The magnitude of the average angular acceleration of the disk is .

Explanation:

Given that,

Angular velocity,

The disk comes to rest,

Time, t = 0.234 s

We need to find the magnitude of the average angular acceleration of the disk. It is given by change in angular velocity per unit time. So,

So, the magnitude of the average angular acceleration of the disk is .

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
