Hi Im currently looking at ballistic missile curves and how to determin impact locations. I found an article discussing this. According to the article several accelerations act on the missile, including two I can't figure out. These are called "propulsive acceleration" and...

Hmmm... The calculation in diferent unit is not a matter here, as my calculator is able output the result in the right units and as well able to convert from kg to amu, Joule to eV amd so on. But I have now calculated the whole thing over again, with all taking the masses og the nucleus and...

My teacher prefer that we use SI-Units, as we will be sure that the results are in SI-Units. Also, I don't know what county the majority of the users of this forum is, but I live in Denmark, and here we use the metric system (Don't know if that even matters here). The Y has 39, and the Zr...

I finally got the right result! Thanks a lot :) I tried only calculation with masses of the mother- and the daugther nucleus, without the β particle itself, and that gave me the 2,28 MeV i was looking for. But, I'm still confused. How can i get it right, when I am ignoring a product? if...

Hi I'm wondering if someone could help me out finding the Q-value fom a beta minus decay. It's a 90Y → 90Zr + e All sources I have says that the energy released is 2,28 MeV, but when i calculate i get 1,78 MeV So far, I've looked up the mass of the 90Y and the Zr90 and the electron...
