B field Field Loop Square

AI Thread Summary

In a uniform magnetic field, a thick square loop made of aluminum with the top half exposed will have constant magnetic flux, resulting in zero induced electromotive force (emf). The discussion highlights that if the magnetic field is uniform, the conditions for inducing emf are not met. Instead, the focus shifts to analyzing the loop's motion under the influence of gravity and resistive forces. This leads to applying Newton's second law to understand the dynamics of the falling loop. Overall, the presence of a uniform magnetic field negates the induction of emf in this scenario.

Homework Statement: I have figured out most of it, Im just not sure what happens in part h) i.e. when entire loop is exposed to B field.

Relevant Equations: n/a

I might be missing something here, however if the magnetic field is present and uniform everywhere as stipulated in part (h), then the flux linked is constant and zero emf is induced.

It would then just be a case of applying Newton II to a falling body with a resistive force.

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'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
