Explanation:
8 × 340 m/s = 2720 m = 2.72 Kilometers
Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.
In case of nuclear fission, the heavier nucleus captures the neutron and splits themselves into daughter nucleus or small fragments. The sum of mass of the fragments is less than the original mass. The missing mass is converted into energy according to Einstein's mass-energy equivalence relation.
