A single-celled animal called a paramecium propels itself quite rapidly through water using its hair-like cilia. A certain paramecium experiences a drag force of Farag -bu? in water, where the drag coefficient b is approximately 0.330 kg/m. If the paramecium's speed v is 0.000157 m/s, what is the magnitude of the propulsion force that the creature must generate to move at this constant speed? magnitude: 2.684 x10-9 N
