if you combine 4 grams of matter and 2 grams of antimatter you get how many grams x c2 of energy and matter?
475765
oh, wow, this is a physics question.\n\nto start, we remember E = mc^2\nthe problem gives 4 grams matter and 2 grams antimatter.\nmy solution would be that 2 grams of matter and 2 grams of antimatter annihilate to produce 4c^2 (2 + 2 = 4) energy.\nthe excess 2 grams of matter remains unaffected.\nthe answer is D.

Einstein's theory: e(energy)=m(mass)c(speed of light) squared so e=mc2

Yeah, it's E=mc^2 and it relates energy and mass.  E is energy, m is mass, c is the speed of light (celeritas).  The equation could come useful in physics, like atomic physics.\n\nWhat did you wanted to know?

By relativity, E = Mc2\n\nIf E = 4 X 10^6 J, then....\n\n4 X 10^6 / c^2 = 4.45 X 10^ -11 kg\n\nWhere C = 299,792,458 m/s

(m)\n\nMatter which consists of antiparticles, elementary particles of ordinary matter, such as protons and electrons, but have an opposite electrical charge. For example, an antiproton has a negative charge while a proton has a positive charge. When a particle of matter and a particle of antimatter come into contact with each other they are destroyed, releasing energy.

Conservation of energy:  KE=PE\n1/2*Mb*Vb^2= (Mb+Mw)*g*h\nVb^2=2*(Mb+Mw)*g*h/Mb\nVb^2=2*(0.01+2)*10*0.1/0.01\nVb^2=402\nVb=20.05 m/s

E=mc^2 \nEnergy = mass * (speed of light)^2, c = the speed of light (approx. 186,000 miles per second).

The answer is 2\n\nWe see it happening all the time when beta plus (positrons) come in contact with electrons, which are their anti-particles. The result is annihilation and two gamma rays. The gammas share (somewhat unevenly) the rest-mass energy of the electron-positron pair (2 times 0.511 MeV = 1.022 MeV). \n\nIf a proton and an anti-proton annihilate (this can happen in accelerators) the energy would be about 2000 times greater.

c2 is the speed of light squared, which is about 186, 355 mph. It is a really huge number.\nIf you want to know a little more about the equation:\nUse a remote control for an example as mass.\n\nif you multiply the mass of the remote control (the amount of matter in the remote control) and the speed of light squared, then the resulting answer, which is energy or e, will have a huge amount of energy relased. It could even be more powerful than an atomic bomb or hydrogen bomb.

nothing what's the antimatter with you! seriously though if you mean antimatter, it's a form of matter in which most of it's properties are reversed.

I assume you mean the whole facts about the anti-matter.  Well CERN does exist and people are trying to create anti-matter. We have produced elementary particles with particle accelerators but I'm not sure about anti-matter.  I would assume it could be held in place with a strong magnetic field though to stop it annihilating, however I seriously doubt they'd have containers which could be transported elsewhere with batteries that run down, that would be a rather stupid idea really.

Antimatter is the most expensive substance ever made.\n\nAt present, antimatter costs $62.5 trillion per gram

Personally I think the reason that there is less antimatter than matter has something to do with the arrow of time.  The last time I checked there was still not a very good explaination of why there is more matter than antimatter.  Its still an outstanding problem in physics.  Its a subject that, as a physicist, I'm very interested in.  Who knows, maybe you'll come up with an explaination.
