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^2c ).
○ it states that all energy in the universe will be converted to mass.

Explanation:

• Analyze each option:
• Option 1: Mass - energy equivalence (from Einstein's \(E = mc^{2}\)) implies that mass is a measure of the energy within an object, as mass and energy are interchangeable.
• Option 2: Mass - energy is conserved, not created or destroyed, so this is incorrect.
• Option 3: The correct formula is \(E=mc^{2}\), not \(E = m^{2}c\), so this is wrong.
• Option 4: Energy and mass are interchangeable, not that all energy will be converted to mass, so this is incorrect.

Answer:

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