what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
"what is the nuclear binding energy of an atom that has a mass defect of 5.0446 10–29 kg?"
to answer this question , the atomic number and the atomic mass of the said atom must be know, so that we can find the mass defect. before we can proceed.
