Several bacteria are propelled by motors that spin hair-like flagella. A characteristic bacterial motor turning at a constant angular velocity has a radius of 1.9x10^-8m, and a tangential speed at the rim 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 the motor to create one revolution?
