Is the mass of an atomic nucleus greater or less than the sum of the masses of the nucleons composing it? Why don't the nucleon masses add up to the total nuclear mass?

This is a question that can't be answered with the given information. Whilst the masses of the three women are nice, the longest and shortest times depends on each's velocity, not given.

Why are the atomic masses listed in the periodic table not whole numbers? Answer Scientists have yet to make the precise measurements. That would be too much of a coincidence. ??>>The atomic masses are average atomic masses. or >>Today's instruments are able to ...

An object with a mass of 20.1 kg is hung from two identical springs vertical. The springs both stretch 0.23 meters from equilibrium with the attached mass. One of the those springs is placed on a horizontal surface without friction and the mass of 20.1 kg is held still next to...

I have no idea what reaction you are trying to explore. For energy released, add the masses of the atoms as reactants, then subtract the masses of the product. That is the mass converted to energy.
