AI Thread Summary
The discussion revolves around solving the equation T=E^2/4*(M+m)c^2 with given values for M, m, E, and c. The user converted atomic mass units (amu) to kilograms but ended up with a surprisingly small result of 2.21 eV. This raised confusion about whether the calculation was correct or if an error occurred. The user expressed frustration over a lack of assistance in resolving the issue. The conversation highlights the challenges in understanding the implications of the calculated energy value.

T=E^2/4*(M+m)c^2
M=61amu,
m=1amu
E=710kev
c=3*10^8m/s
I conver amu to kg

The Attempt at a Solution


direct subtitution but the thing that I got the answer which is 2.21eV which is very small and it confused me have I did something wrong or it is true

why no one helped me?
 
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...
