Apparent Magnitude of Sun at 8000 Parsecs from Galactic Center

AI Thread Summary
The extinction to the galactic center is approximately Av=20mag, and the apparent magnitude of the Sun at 8000 parsecs is being calculated using the luminosity-distance formula. The formula proposed is m=20mag+5*(log(8000)-1), which is a step in the right direction. However, the discussion highlights the need to consider the Sun's apparent magnitude without extinction for a complete understanding. The conversation emphasizes the importance of accurately applying the formula to determine the Sun's apparent magnitude at that distance.

The extinction to our galactic center is about Av=20mag. What would be the apparent magnitude of our sun at the 8000parsec distance of the galactic center?

From what I know, I think I need to use http://en.wikipedia.org/wiki/Absolute_magnitude#Computation the luminosity-distance formula. So I'd have m=20mag+5*(log(8000)-1) . Is this correct, am I missing something, or am I going at this totally wrong?

Thanks!

Close, but not quite. What would the sun's apparent magnitude be at that distance if there were no extinction?
 

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...
