Time-Energy Uncertainty relation

AI Thread Summary
The discussion revolves around a homework question related to the Time-Energy Uncertainty relation, where the participant's calculated answer of approximately 66 eV conflicts with the provided answer of 6.6 eV. The participant uses the equation ΔE = h/2Δt to derive their result, which aligns with another contributor's confirmation of the method. The consensus is that the original answer given is likely incorrect. Clarification on the uncertainty principle and its application in this context is requested.

Homework Statement


So I have this homework question and the answer that was given to me to check the answer that I have does not match with my answer. The question I have to complete is shown below:
question 8.JPG


The answer given to me is D, 6.6eV

Homework Equations



\Deltat\DeltaE = [STRIKE]h[/STRIKE]/2

Rearranged for \DeltaE:

\DeltaE = [STRIKE]h[/STRIKE]/2\Deltat

The Attempt at a Solution



When I attempt the question my answer is 65.8eV, approximately 66eV. This matches with selection c, which makes me believe that the answer given is incorrect and my method is correct.

If someone could clarify this uncertainty (no pun intended), that would be greatly appreciated.

Thanks

That method looks correct, and it also gives me 66 eV.
It would seem to me that the answer you were given is not right.

(Unintended pun duly noted).
 

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...
