Which statement best describes the relationship between atoms and nuclear forces? Weak nuclear forces hold the nucleus of an atom together. Strong nuclear forces
are responsible for breaking down atoms.
Strong nuclear forces hold the nucleus of an atom together. Weak nuclear forces
hold neutrons and electrons together.
Weak nuclear forces hold small atoms together. Strong nuclear forces hold large
atoms together.
Strong nuclear forces hold the nucleus of an atom together. Weak nuclear forces
are involved when certain types of atoms break down.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
