Problem 4 (Drag forces on a bacterium) Imagine a bacterium which is a sphere 10 5 m in diameter. It swims through water (which has a density of 1,000 kg/m and a viscosity of 8.9 x 10 4 Pa - s ) at a speed of 3 x 10 5- A. What is the magnitude of the viscous drag force acting on this bacterium? (Express your answer in pN.) Question 9 B. Calculate the weight of this bacterium. The density of the bacterium is 20% higher than that of water. Express your answer in pN. Question 10 C. Assuming the drag coefficient of the bacterium is 1, what is the magnitude of the inertial drag force on the bacterium? Use scientific notation (ex. 6.02 x 1025 would be written as "6.02E23") and express your answer in pN
