Explanation:

Question 3

In radiography, mAs (milliampere - seconds) and IR (Image Receptor) exposure have a direct proportional relationship. As mAs increases, the number of x - ray photons produced increases, which leads to an increase in IR exposure. Conversely, if mAs decreases, IR exposure decreases.

kVp (kilovolt - peak) is the potential difference that accelerates electrons in the x - ray tube. According to the principles of electrostatics and electron acceleration, an increase in kVp means a greater accelerating potential. This greater potential will cause the electrons to accelerate more, resulting in an increase in their speed.

The energy of an electron accelerated through a potential difference is given by \(E = qV\) (where \(q\) is the charge of the electron and \(V\) is the potential difference, related to kVp). When kVp (and thus the potential difference \(V\)) increases, the energy \(E\) of the electrons, which is kinetic energy in this case, also increases.

Answer:

Directly proportional (or "Direct relationship"; as mAs increases, IR exposure increases and vice - versa)
