Green Flash
Hey Janitor
I did a little research on that green flash from the sun from your original question. The green flash IS true and is quite easily explained. The phenomenon is caused by the layers of Earth's atmosphere acting like a prism. I got that from the website below. I...
got it
thanks!
yeah I got the answer, apparently I wasn't taking into account the coulomb repulsion effect. I did a little reading and found this equation:
Eb = C1(A) - C2(A^2/3) - C3 Z(Z-1)/A^1/3 - C4(N-Z)^2/ A
where C1 = 15.7 MeV, C2 = 17.8 MeV, C3 = 0.71 MeV, C4 = 23.6 MeV
I don't...
I'm trying to figure out the binding energy of 24 Mg. That is (12 protons and 12 neutrons. I keep getting a negative number. Using the equation:
Eb (MeV) = (ZMp + NMn - Ma)931.494 MeV/u I should be able to get the right answer but my mass defect ( delta m) is negative. What am I missing...
