Special Relativity and the Relativity of Simultaneity.

AI Thread Summary
The discussion centers on the relativity of simultaneity in the context of a rocket and a galaxy. It explores how the position of the rocket affects the perception of explosions occurring in the galaxy, specifically that the rocket will see the light from explosion R before L due to its frame of reference. The possibility is raised that if the galaxy moves quickly enough, it could change the order in which the rocket perceives the explosions. However, the clarification emphasizes that the rocket's entry point into the galaxy does not allow for it to shift positions relative to the galaxy after the explosions occur. This highlights the complexities of simultaneity in special relativity.

The position of the rocket is not specific. We just know that it is at the left of the galaxy. We know that R will explode first in the rocket's frame.

Maybe the galaxy could be moving fast enough so that the time it takes for L to explode is enough for the rocket to see R's light first. In other words, in the time delay L explodes after R, maybe the galaxy could go past the rocket (end up to the left of the rocket). If the galaxy ends up to the left of the rocket and L explodes after that, then R is for sure the first light that the rocket sees.

What did the problem statement say about the relationship between the rocket and the galaxy? Does it suggest to you any reason why your reasoning might be flawed?
 
Hi, the rocket "enters the galaxy from left". That does NOT mean that after R explodes, in the time it takes for L to now explode, the rocket could now be to the right of the galaxy.
 

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'

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...
