which statement accurately describes mass - energy equivalence?\nit includes the idea that mass is a measure of the energy within an object.\nit states that mass - energy can be created or destroyed.\nit can be represented using the formula e = m²c.\nit states that all energy in the universe will be converted to mass.
Answer
Brief Explanations:
According to Einstein's mass - energy equivalence principle, mass is a form of energy. The correct formula is $E = mc^{2}$, and mass - energy is conserved and cannot be created or destroyed. Also, not all energy in the universe will be converted to mass. The idea that mass is a measure of the energy within an object is part of mass - energy equivalence.
Answer:
It includes the idea that mass is a measure of the energy within an object.
