Question

fusion reactions release energy according to einsteins equation.$e = mc^2$$f = ma$$e = hv$$p = mv$7/30

Explanation:

Einstein's mass-energy equivalence equation describes the relationship between mass and energy, which explains the energy released in fusion reactions (where a small amount of mass is converted into a large amount of energy). The other equations relate to force, photon energy, and momentum, which are not relevant to this process.

Answer:

$E = mc^2$
