AI Thread Summary
The discussion focuses on calculating the distance traveled and the displacement of an ion in a mass spectrometer, which follows a semicircular path with a radius of 15.2 cm. For the distance traveled, the formula used is s = πr, resulting in a specific distance based on the radius. The displacement, however, requires clarification, as it involves determining the straight-line distance from the starting point to the endpoint of the semicircular path. The Pythagorean theorem is suggested as a method to find this displacement. Overall, the conversation centers on understanding the calculations related to the ion's movement in the mass spectrometer.

Homework Statement


An ion in a mass-spec follows a semicircular path of radius 15.2 cm.
a)What are the distance it travels
b)The magnitude of its displacement

The Attempt at a Solution



a) s = pi.r
r = 15.2cm

s = pi(15.2cm)

b) what is part(b) asking?

Ok I think I had it figured out.

particle at position(15.2,15.2)
Pythagoras theorem should solve it.
 
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...
