AI Thread Summary
The discussion centers on the decay of an atom of 28_13 Al into the stable nuclide 28_14 Si through beta particle emission. There is confusion about whether 28_14 Si is a positive ion or a neutral atom. The consensus suggests that after the decay, the remaining atom is indeed neutral, as the emission of a beta particle (an electron) does not change the overall charge of the atom. The importance of charge conservation is emphasized, indicating that the decay process results in a neutral atom rather than a positive ion. Ultimately, 28_14 Si is confirmed to be a neutral atom.

Homework Statement



An atom of 28_13 AI decays into stable nuclide 28_14 Si by emitiing a beta particle.
What's 28_14 Si ?
the ans given is positive ion?

in my opinion, it should be a neutral atom... which is correct?

What's your reasoning? Hint: What's a beta particle?
 
If the 28 _13 nucleus decay then the positive ion is formed? Am I right? But here's an atom not nucleus

Think about conservation of charge. If a beta particle is emitted, what does that tell you about what remains?

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...
