Einstein’s equationE=mc2:a) applies only to rest mass.b) applies only to electromagnetic radiation.c) applies only to nuclear reactions.d) is only valid in non-inertial frames.e) is general. All forms of energy have inertial mass and a gravitational effect. Rest mass isitself a special form of energy like electromagnetic field, thermal, or kinetic energies.038 qmult 01220 1 3 1 easy math: E=mc**2 applied to electronExtra keywords:physci KB-93-3321.
