I have a physics assignment, the purpose of which is to determine the mass of the top quark from proton-antiproton collision data gathered at Fermi National Accelerator Laboratory in 1995. Please go to www.google.com In the search box, put in quotes "since protons have the same mass" and click Search. The first file you s ...continues
Question: The naturally occurring isotopes of potassium are: 39 K (abundance 93.10%) 40 k (abundance 0.0118%) 41 k (abundance 6.88%) 40K is radioactive and decays by Beta- decay with a half life of 1.29 mulitplied by 10`9 years. a) How many protons and neutrons do each of the three isotopes of potassium have? b) Ca ...continues
Seeking 2 answers to previously asked Question on Atomic Physics
The naturally occurring isotopes of Potassium are: 39 K (abundance 93.10%) 40 K (abundance 0.0118%) 41 K (abundance 6.88%) d) What percentage of 40 K nuclei will decay in the next 10 000 years? (The answer that i seeked from brain mass before was provided to me as 1.000005373, and therefore alomost 100% of the origi ...continues

Sketch the sixth-order Feynman diagram
Sketch the sixth-order Feynman diagram representing Delbruck scattering: r + r -> r+ r. (This process, the scattering of light by light, has no analog in classical electrodynamics.) This question is from the textbook 'Introduction to elementary particles' by David Griffiths.
