Question
Microwave ovens rotate at a rate of about 6 rev/min. What is this in revolutions per second? What is the angular velocity in radians per second?
Step 1
We know that there are 60 seconds in a minute, so we can use this to convert the units. We have: \[6 \frac{\mathrm{rev}}{\mathrm{min}} \times \frac{1 \mathrm{min}}{60 \mathrm{s}} = 0.1 \frac{\mathrm{rev}}{\mathrm{s}}\] Show more…
