AI Thread Summary
The discussion revolves around a question from Motion Mountain (MM) regarding the color of the line separating a black spot from a white background, with the answer suggesting that color applies to objects rather than backgrounds. Participants express confusion over this concept and seek clarification on its meaning. Additionally, there is a mention of the usefulness of LaTeX for discussing Motion Mountain content, highlighting its convenience for mathematical expressions. The forum supports LaTeX to facilitate clearer discussions on complex topics. Overall, the conversation emphasizes the need for better understanding of color theory and the advantages of using LaTeX in academic discussions.

I just came across a question in MM that said what is the color of the line separating a black spot from a white background
the answer was color is applied to objects not to backgrounds. i did not understand anything..anybody did?

what does MM mean?

PS: why do we support this forum with Latex for example $\overrightarrow {r_C } = \frac{{\int {\overrightarrow r dm} }}{{\int {dm} }}$
if we have Latex available here, it's more convenient to disscuss
 


Motion Mountain. it's available in pdf and is said to be the best available..
 
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...
