Why is it important to understand the correct meaning of (c) in (E=mc^2)?
Answer and explanation
Correct answer: Because (c) represents the speed of light in vacuum
In Einstein’s equation (E=mc^2), (c) is the speed of light in vacuum. It appears as (c^2), so it has a major role in relating mass and energy. Electric current is generally represented by (I), so option C is not correct. Exam tip: learn the standard meaning of every symbol used in a formula.
