A typical bacteria cell is around 5 micrometers in diameter. The nearest we can bring our eyes to an object and still focus on it is about 25 centimeters. Using this information and the Rayleigh criterion, what size eye opening (pupil diameter) must we have in order to resolve two adjacent bacteria? Give your answer in millimeters. (use the wavelength at the midpoint of visible light, 550nm, for your calculations)

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
