1. [3 pts) Many diseases, including COVID-19, spread because the virus is carried by tiny particles (diameter - 10 um) suspended in air, emitted when people sneeze, cough, exhale, and talk. A recent study found that these suspended particles have an effective diffusion coefficient of 1.6 x 10-3 m²/s. We have often been advised to stay 6 feet (1.83 m) away from other people in order to reduce the likelihood of contracting COVID-19. For the given diffusion coefficient, how much time would it take for these particles to diffuse this distance? Assume 3D diffusion.

Questions 3 of 12 Review Constants 1 Periodic Table Part A Larger animals have sturdier bones than smaller animals. A mouse's skeleton is only a few percent of its body weight, compared to 16% for an elephant. To see why this must be so, recall, that the stress on the femur for a man standing on one leg is 1.4% of the bone's tensile strength. Suppose we scale this man up by a factor of 10 in all dimensions, keeping the same body proportions. (Assume that a 70 kg person has a femur with a cross-section area (of the compact bone) of 4.8 x 10-4 m², a typical value.) Both the inside and outside diameter of the femur, the region of compact bone, will increase by a factor of 10. What will be the new cross-section area?
