HW help: Potential difference between axles?

AI Thread Summary
To find the potential difference between the ends of the axles of an automobile moving at 30 m/s in a vertical magnetic field of 0.00008 webers/m², the relevant equation involves calculating the electromotive force (EMF) induced across the axles. The length of the axles is 2 meters, which is essential for the calculation. The formula for EMF is given by EMF = B * L * v, where B is the magnetic field strength, L is the length of the conductor, and v is the velocity. Substituting the values into the equation will yield the potential difference. This problem illustrates the principles of electromagnetic induction in a moving conductor within a magnetic field.

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...
