Some bacteria are propelled by motors that spin hair-like flagella.A typical bacterial motor turning at a constant angular velocityhas a radius of 1.9x10-8m, and a tangential speed at therim of 2.6x10-5 m/s.
(a) What is theangular speed (the magnitude of the angular velocity) of thisbacterial motor?
(b) How long does it take the motor to make one revolution?
