Question

In nuclear fission, the ratio (mass of products)/(mass of parent nucleus) is generally:

G1 Physics · Accepted Answer

Fission releases energy Q > 0. By E = Δmc², some rest mass changes into energy, so total product rest mass is lower than reactant rest mass (compare complete initial/final nuclear systems). Final answer: Option C.
