Calculating Free Energy in Nuclear Fuel Reactions

AI Thread Summary
To calculate the free energy from 1 kg of nuclear fuel, the reaction 235U + n → 139Ba + 86Kr + 11n + 176 MeV is considered. Clarification is sought on whether the energy release is 176 meV or 176 MeV, as this significantly impacts calculations. The discussion also touches on the need to balance the nuclear equation and how to determine the number of atoms in 1 kg of uranium. The original poster eventually finds the information they needed through a YouTube search. Accurate energy calculations are crucial for understanding nuclear fuel reactions.

Can you find how many atoms are in 1 kg of uranium? Is the energy release from a single reaction 176 meV or 176 MeV? It makes a whole lot of difference.
 
nevermind, I found what i was looking for on youtube. Thanks!
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
Thread 'A cylinder connected to a hanged mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
