Can a radioactive element decay by emitting more than 1 particles at once?

AI Thread Summary
Radioactive elements typically decay by emitting only one particle at a time during a single decay event. For example, a radioactive isotope like Uranium will not emit multiple particles simultaneously, such as two beta and one alpha particle. Instead, it undergoes a sequential decay process, where it first emits one particle and transforms into another element before potentially decaying again. In fission, however, a nucleus can split into two smaller nuclei while releasing multiple neutrons, usually averaging between two to three. Overall, simultaneous emission of multiple particles in a single decay event is not observed in standard radioactive decay processes.

Staight question :

Can a radioactive element decay by emmitting more than 1 particles at once? ie. can a radioactive Uranium decay 2 beta and 1 alpha particles at the same time, or it must decay 1 particle (eg beta), itself becomes another elements and then decay further?

thanks

The short answer is no.

Radioactive decay is essentially exclusively by one particle (mode) during a single event.

In the case of fission, where the nuclear breaks apart into two nuclei, a number of neutrons are also released. The number of neutrons varies between 2 or 3, with the average value in between.
 

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 '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...
