The reason the correspondence between mass and energy has been only recently discovered is that
a. the changes involved on earth are very small.
b. we only recently have had accurate enough instruments.
c. conventional methods cannot measure the changes involved.
d. all of the above
e. none of the above

Answer;

D. all of the above

The changes involved on Earth are very small. We only recently have had accurate enough instruments. Conventional methods cannot measure the changes involved.Explanation;Mass-energy equivalence states that mass is concentrated energy. This is shown by the Einstein's equation E = mc², where E is the energy, m is the mass and c is the speed of light.The Einstein's equation shows that energy and mass are interchangeable. The mass of an object depends on the amount of energy in it. From the Einstein's equation, mass and energy can be transformed into one another.
