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 2.9x10-5 m/s. (a) What is the angular speed (the magnitude of the angular velocity) of this bacterial motor? (b) How long does it take themotor to make one revolution?
