How Do You Calculate the Length of Wire in a Generator Coil?

AI Thread Summary
To calculate the length of wire in a generator coil with 80 turns and a 0.35 T magnetic field, the relevant equations include the emf formula E = NABωsin(ωt) and the angular frequency ω = 2πf. The peak voltage is determined to be 169.71 V by converting the rms value of 120 V. The angular frequency is calculated as 376.99 rad/s using the generator frequency of 60 Hz. The user successfully solved the problem, indicating they found the necessary steps to determine the wire length.

Homework Statement


A generator uses a coil that has 80 turns and a 0.35 T magnetic field. The frequency of this generator is 60.0 Hz, and its emf has an rms value of 120 V. Assuming that each turn of the coil is a square (an approximation), determine the length of the wire from which the coil is made.


Homework Equations


E=NABwsinwt
w=2pif



The Attempt at a Solution


Vpeak=sqrt2 * 120= 169.71
w=2pi(60)=376.99
169.71=80*A*.35*376.99*(sin367.99*t)
but where do i go from here?

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...
