Which of the following conditions are diagnostic x-rays most likely to be performed under?

The technical factors for a hand x-ray were set at 4 mAs and 55 kVp. A repeat image was taken at 2.5 mAs and 65 kVp. Would you expect the differential absorption to be higher or lower in the second image?

After a Compton interaction with an outer shell electron of a calcium atom (BE = 0.04), the recoil electron sped away with 10 keV of energy. The scattered photon was deflected at an angle of 75 degrees from the original photon retaining 62 keV of energy. What was the energy of the incident photon?
