Achild has accidentally ingested a magnet. your x-ray machine allows several kvpsettings between 50kv and 120kv. is x-ray imaging a suitable modality in the sense that good contrast can be achieved between the magnet and surrounding tissue/bone? why / why not?

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
