Answer to Question 1

kVp

Rationale: Kilovoltage affects contrast on an image, but also contributes to density.

Answer to Question 2

the sesamoids are projected free of the head of the first metatarsal

Rationale: If performed correctly, a tangential, or skimming, beam will cast sesamoids free of superimposition of the head of the first metatarsal.
