njordsifusansooI'm doing my physics homework right now...can't decide if some of these questions are atomic physics, nuclear physics, or both. For example...
now I'm not sure of my answer (and I'm not going to post it even if I have the right answer), but the solution involves using E=mc^2 (well most of the questions on this assignment have mc^2 cropping up). Erin if your reading this and haven't figured it out, look on pages 87-88 of our textbook.
Overall I am glad Erin convinced me to take this course. Despite making my head hurt on occassion (okay boys and girls, lets demonstrate how fast moving particles warp space and time), I am learning interesting things from this class. And to think we haven't even gotten to the third chapter yet.
now back to my physics homework since I won't have time to do it tonight.
The energy released in the fission of a U235 nucleus is about 200 MeV. How much rest mass (in kg) is converted to energy in this fission?
