AI Thread Summary
The observed redshift of a galaxy's spectral lines indicates its velocity relative to the Milky Way. The calculation of redshift (Z) shows a value of 0.101, derived from the difference in observed and emitted wavelengths. While redshift is primarily associated with velocity, it can also be used to estimate distance through Hubble's Law. Hubble's Law relates redshift to distance, suggesting that greater redshift corresponds to greater distance from the Milky Way. Therefore, while the initial calculation focuses on redshift, it is indeed relevant for determining the galaxy's distance.

A galaxy is observed to have a significant redshift in all of its spectral lines. The line normally seen at a wavelength of 327 nm is instead observed at 360 nm. How far is this galaxy from the milkyway

My approach


All I can calculate here is the red shift based on the formula

Z= observe wavelength- emitted/ emitted


Z= 360-327/327
=0.101

This has nothing to do with distance or does it?

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...
