ne coll bacteria is suspended in water which has a viscosity of r 0 8 x 10 N s m and a density of 1000 kg m Assuming the water is absolutely still no net velocity the bacteria will fall downward unde he influence of gravity Assuming the bacteria has a mass of 680 femtograms 1 femtogram 10 18 kg and a diameter of 0 25 um what is the absolute magnitude of the terminal velocity of this bacteria in water Ignore buoyancy for the purposes of this problem Submit Answer Tries 0 99 What is the absolute magnitude of the terminal velocity for this bacteria if it were falling through air 1 989 x 10 Nes m and a density of 1 2 kg m Submit Answer Tries 0 99 How important is the force of gravity to the motion of bacteria through air compared to the force exerted by the motion of the air itself In other words consider the terminal velocity of the bacteria and compan o your estimate of the speed with which air moves in a typical room The force of gravity completely dominates the forces acting on the bacteria i e the motion of air can be ignored The motion of air completely dominates the forces acting on the bacteria i e gravity can be ignored Tod
