Question

which statement accurately describes mass - energy equivalence?
it includes the idea that mass is a measure of the energy within an object.
it states that mass - energy can be created or destroyed.
it can be represented using the formula ( e = m^{2}c ).
it states that all energy in the universe will be converted to mass.

Explanation:

• According to the law of conservation of mass - energy, mass - energy cannot be created or destroyed (so the statement "It states that mass - energy can be created or destroyed" is wrong).
• The correct formula for mass - energy equivalence is \(E = mc^{2}\), not \(E=m^{2}c\) (so the statement "It can be represented using the formula \(E = m^{2}c\)" is wrong).
• The law of mass - energy equivalence does not state that all energy in the universe will be converted to mass (so the statement "It states that all energy in the universe will be converted to mass" is wrong).
• Mass - energy equivalence implies that mass is a measure of the energy within an object. The formula \(E = mc^{2}\) shows the relationship between mass (\(m\)) and energy (\(E\)), where \(c\) is the speed of light.

Answer:

It includes the idea that mass is a measure of the energy within an object.
