Viruses are much smaller than bacteria. For example, the novel coronavirus is a spherical particle of outer diameter 110 nm, while streptococcus bacteria are 1.6 ?μm in diameter. The virus is also found to be slightly more dense than the bacteria, with the density of coronavirus being 1.15 kg/L and that of strep being 1.1 kg/L. During an infection, both are found in the bloodstream (blood density is 1.05 kg/L; blood viscosity is 3.5××10−3−3 Pa⋅⋅s). (a) A sample of blood...
