Experiment Lead Rutherford

AI Thread Summary

The discussion centers on determining the Q value for lead in the context of the Rutherford scattering experiment, where gold's Q value is established at 79e due to its atomic number of 79. Participants suggest referring to a periodic table to find lead's atomic number, which is 82, indicating that lead has 82 protons in its nucleus. Consequently, the Q value for lead would be 82e. This value is essential for calculating the turning distance in the experiment when using lead instead of gold. Understanding these Q values is crucial for accurate interpretations of scattering results.

in a problem using the Rutherford scattering experiment, i Need to find what the turning distance would be using lead instead of gold. I have that gold has a Q= 79e, what would the Q = ?? for lead?

Gold has an atomic number of 79 - hence 79 protons in the nucleus. The charge is then 79e.

What do you think this would be for Lead? You might need a periodic table to help you with this one.

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
