Question

The flywheel on a steam engine rotates 60 revolutions every 15 seconds what is the flywheel rate of revolution per second? need the unit rate too.​

Answer 1

The answer for that question is 4 per second

Explanation:

Just put that answer i know it on your choices i looked up goodle for this answer so your welcome

Hope this help

Pls leave a thanks if it did

Answer 2

The flywheel rate of the flywheel is 4 revolutions per second.

Explanation:

From Rotation Physics we understand that flywheel rotates at constant rate. In this case, angular speed (
`\dot n`), measured in revolutions per second, is the number of revolutions done by the flywheel at a given interval of time. That is:

`\dot n = (n)/(t)` (Eq. 1)

Where:

`n` - Number of revolutions done, measured in revolutions.

`t` - Time, measured in seconds.

If we know that
`n = 60\,rev` and
`t = 15\,s`, then the angular speed of the flywheel is:

`\dot n = (60\,rev)/(15\,s)`

`\dot n = 4\,(rev)/(s)`

The flywheel rate of the flywheel is 4 revolutions per second.
