    Calculating Energy Released When Hydrogen & Anti-Hydrogen Collide

    So theirs this question Particle accelerators can be used to accelerate particles up to 95% the speed of light. Determine the energy released when 1 hydrogen atom collides with an anti-hydrogen atom. E=mc^2 = (1.00794)(2.998x10^8 x 0.95)^2 = 1.00794 x 8.1225 x 10^ 16 = 8.1869 x 10^16...
