For a chest x-ray imaging system with a perfect point source. If we require that the intensity variation is smaller than 10% across the image when imaging a slab of material with uniform attenuation coefficient and negligible thickness. Suppose the source-to-detector distance is 1 m, what is the maximal size (radius) of the image?

to a new home. Try improved 2. Suppose that a baseball player is in a batting cage taking practice from an automatic pitching machine. ketch ( The back of the cage is 5 m wide and 3 m tall. The machine malfunctions and starts shooting balls at a rate of 4 balls/second, randomly distributed throughout the cage. The batter freaks out and just freezes presenting a cross-section of 0.75 m² to the machine. How long does it take before it is likely that he is hit by a ball?
