How Does Time Affect the Radioactivity of Substances with Different Half-Lives?

AI Thread Summary
The discussion focuses on the relationship between time and the radioactivity of two substances, K and L, which have the same initial activity but different half-lives, TK and TL. After a time T, the activity of substance K is observed to be half that of substance L. Participants are tasked with expressing this relationship in terms of T, TK, and TL. The conversation highlights the mathematical implications of half-lives on radioactive decay and how they influence the remaining activity over time. Understanding these dynamics is crucial for accurately modeling radioactive decay in various applications.

Question:
A sample of radioactive substance K and a sample of another radioactive substances L have the same initial activity. the half life of K is TK and the half life of L is TL. After a time T, the activity of K was half the activity of L. Expression in term of T, TK, and TL.

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...
