Relative to the sum of the masses of its constituent nucleons, the mass of a nucleus is: greater the same smaller sometimes greater and sometimes smaller

Answer is: smaller.

Protons and neutrons are in the nucleus of an atom.

Nuclear energy is the energy found in the nucleus of an atom.

The missing mass of a nucleus is called its  binding energy, the energy needed to break it up  into separate protons and neutrons.

Average binding energy per nucleon equals total  binding energy divided by mass number (sum of protons and neutrons in an atom).

particle   p is an electron and particle q is a neutron

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
