Respuesta :

E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself


So I THINK that A is the right answer but i may be wrong.


I hope this helped :)

What we know by the textbook is that E = [tex]mc^{2}[/tex] is the equation of physics. Simplified, The equation is: "Energy = mass times the speed of light squared.". Our knowledge on physics and that equation understandment determines that A is the correct choice.
