AI Thread Summary
The discussion focuses on a homework problem involving the fission of U235, specifically calculating the number of atoms consumed and the mass of uranium used daily in a reactor. Key points include the energy released per fission event (200 MeV) and the reactor's output (700 MW) with a 20% efficiency. Participants express confusion about the necessary units and concepts, such as MeV and MW. Clarification on these units is essential for solving the problem effectively. Understanding the relationship between energy, power, and mass is crucial for completing the calculations.

Homework Statement


WHen an atom of U235 undergoes fission in a statement reactor about 200MeV energy is liberated. suppose that a reactor using U235 has an output of 700MW and 20% efficient:

For starts, what units to have, and what units do you need to solve for? What is an MeV? What are MWs?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

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 hanging mass'

Thread 'A cylinder connected to a hanging 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...
