Suppose you were to try to create a
proton-antiproton pair by annihilation of
two very high-energy gamma rays of the
same wavelength heading toward each
other. The proton and the anti-proton
have the same masses, but opposite
charges. What would be the minimum
energy needed for each photon? (e = 1.60
× 10-19 C, m proton = 1.67 × 10-27 kg, c =
3.00 × 108 m/s)
939 MeV
O1.022 MeV
O 12.2 MeV
O 1880 MeV
What is the percentage difference mass loss between a Helium nucleus and 4 protons?
My math came out to 99% but I think I did something wrong (this assumes the mass for of 4 protons is 6.6792 x 10^-27kg and a the mass of a helium nucleus is 6.6892e x 10^-27kg (Units need to be in kilograms to use with e=mc^2)
A speck of carbon dust may contain as many as 30 billion atoms of carbon, each atom having a mass of 2.00 x 10-23 grams. Suppose the mass of all the atoms in a speck of carbon dust were converted entirely to energy and applied to the kinetic energy of a baseball. How fast would the baseball be moving? (Mass of baseball = 0.145 kg. )
(1 gram = 1 x 103kg) (KE = ½ mv2) (1 billion = 1 x 109)
