An electron enters a volume V with kinetic energy 4MeV, and carries 0.5 MeV of that energy out of V when it leaves. While in the volume it produces a bremstrahlung x-ray of 1,15MeV which escapes from V. What is the contribution of this event to:
(a) The energy transferred?
(b) The net energy transferred?
(c) The energy imparted?
