A few bacteria are propelled by motors that spin hair-like flagella. A typical bacterial motor turning at a constant angular velocity has a radius of 1.3 x 10-8 meter, and a tangential speed at the rim of 2.6 x 10-5 m/s.
(a) Find the angular speed of this bacterial motor?
(b) Find how long does it take the motor to make one revolution?
