Is it true Emc²?

Answer 1

no Emc^2 is not true

e=mc^2 is true however

Answer 2

Hahahahahahahahahahahahahahahahahahah

Ok, now that I'm done laughing my *** off... E = mc^2 is correct. It's actually a relatively (no pun intended) simple idea: all matter can be turned into energy, and vice-versa.

Proof is in the fact that when an atom of uranium is split in a fission reaction, two neutrons, and two smaller atoms are the products, along with heat. The neutrons and smaller atoms add up to a mass which is less than the original uranium atom. Where did the mass go? Look no further than the heat produced: energy can be neither created, nor destroyed.

Therefore, in this case, matter has turned into energy, which is exactly what E = mc^2 predicts.

Answer 3

Is it true? It is true in theory and practice has also shown it to be real as well. How is this formula derived is a better way to pose this question. It's not like they made it out of the blue. The theory of energy and matter comes from the fact that there is a wave-particle duality of matter. All matter displays the characteristics of both particle and wave. A French scientist named Louis de Broglie first proposed this hypothesis and along with this calculated what the theoretical wavelength of a given particle would be. He proposed that the wavelength of a particle is inversely proportional to the particles momentum. The constant of proportionality was found to be Planck’s constant. Maxwell Plank had originally proposed that energy of a wave is proportional to its frequency. Using these equations, one can correlate energy to mass of a given particle through the given particle’s theoretical wavelength.

λ=h/p=h/mv
λf=v
E=hf
E=hv/λ
E=hv/(h/mv)
E=mv^2
Erev=mc^2 (relativistic energy is equal to mass time the speed of light square since the speed of light is constant to all reference points.)

Answer 4

E=mc²
this implies that e is propational to mass.Mass can be converted to energy and energy can be converted to mass .This is true in case of cosmic rays in which a photon with energy and zero mass is converted to positron with mass and vice versa.
Hence it is an accurate relation

Answer 5

Hi George, Now bear in mind I've been out of school longer than
I would like to remember but I believe, and you can correct me,
that the equation is actually laid out E=mc2. Developed by
Albert Einstein it represents the law of relativity. Good luck
and thanks for the honor of participating. Good night to you,
sir.

Answer 6

Hi. So far every experiment has demonstrated that E=mc^2 to the limits of our ability to measure.

Answer 7

No! The formula is E = m x c x c

Where E = Energy, m = mass and c = speed of light.

Answer 8

Try asking someone who survived the A-bombs dropped on Hiroshima and Nagasaki.

Answer 9

have you seen a nuclear explosion. the answer is yes

think about this at thanxgiving dinner, theres enough energy in all the atoms of the turkey to vaporize half the middle-east. if only i could get a turkey bomb to work. ;-)

Answer 10

no actually e=mc^2

you forgot the =
