Several bacteria are propelled by biological motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocity has a radius of 1.21 10-8 m, and a tangential speed at the rim of 2.32 10-5 m/s.
1. What is the angular speed (the magnitude of the angular velocity) of this bacterial motor?
2. How long does it take the motor to make one revolution?
