Question

whose work predicted that mass could be converted into energy and vice versa?
enrico fermi
otto hahn, lise meitner, and fritz strassmann
albert einstein

Explanation:

Einstein's famous equation \(E = mc^{2}\) shows the equivalence of mass (\(m\)) and energy (\(E\)), predicting that mass can be converted into energy and vice - versa. Enrico Fermi is known for work in nuclear physics (e.g., the first nuclear reactor). Otto Hahn, Lise Meitner, and Fritz Strassmann are associated with nuclear fission discovery.

Answer:

Albert Einstein
