An electron and a positron,
with a mass of 9.1 x 10-31
kilograms, annihilate
each other, producing
two photons. What is the
approximate energy of
each emerging photon? It
is 0.51 Mev 2.0 MeV 4.0
MeV 1.02 MeV It cannot
be determined unless the
frequency of the photon is
known.
Recently scientists have discovered how to contain an anti-hydrogen atom, an element made of an anti-proton and an anti-electron, both of which have the same mass as their real matter counterparts. When anti-matter and matter collide, they annihilate each other and form pure energy. How much energy is given off when anti-hydrogen and hydrogen atom collide?
