    Magnitude Vectors
AI Thread Summary
The discussion revolves around ordering five vectors by their magnitudes, with the user initially ranking them incorrectly as AECDB. The magnitudes calculated for each vector are A = 42.178, B = 44.407, C = 43, D = 44.226, and E = 42.426. The correct order of increasing magnitudes should be A, E, C, D, B, leading to the final ranking of AECDB. The user is advised that while their method for calculating magnitudes is correct, there may be a computational error affecting their rankings. The conversation emphasizes the importance of careful calculations in vector magnitude problems.

Homework Statement



Five vectors are listed below. Select them in order of increasing magnitudes, from shortest to longest. If B is smallest, then A, C, D, and finally E is the largest, enter BACDE (Note: If of equal length, then enter in the order listed.)
A) 23i-31j-17k
B) 36j+26k
C) 43j
D) 20i-34j-20k
E) 30i+30j


Homework Equations



magnitude = sqrt (i^2 + j^2 + k^2)

The Attempt at a Solution



I found:

A = 42.178

B= 44.407

C = 43

D = 44.226

E 42.426

I ranked: AECDB or even follow the order list: AECBD => It's showing wrong?

Could anyone explain what's going on? I'm really confused because I think I'm doing the right way!

Thanks!

As i see you squared the coordinates and took the root of their sum. Well that's the right way. probably some computation error. but the method is correct.
 
Anyone has different ideas?
 

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...
