Atomic physics - nuclear fission

AI Thread Summary
In the discussion on nuclear fission, participants analyze three statements to determine which are incorrect. Statement (1) is false because fission typically produces fragments of unequal masses. Statement (2) is also incorrect, as naturally occurring elements do not undergo spontaneous fission. Statement (3) misrepresents a chemical reaction as nuclear fission, making it incorrect as well. The confusion surrounding the definition of naturally occurring elements and the nature of fission reactions is a central point of inquiry.

Homework Statement
1. Which of the following statements is / are not correct?

(1) In fission, two large fragments of equal masses are produced from a nuclide.
(2) Natually occurring elements perform fission spontaneously.
(3) 2 H2O --> 2H2 + O2 involves nuclear fission.

The Attempt at a Solution


3. It's a MC question and the answer is

D (1), (2) and (3)

My question is: I don't understand the meaning of statement (2).
Thus I 've got a wrong answer.
Can anyone please kindly explain to me ?

Do you know what a naturally occurring element is? How would you define a naturally occurring element?

Argee! That's why i don't know how to solve this question.
 
Let's think about (3) for a second. What's the answer and why ?

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...
