How Fast Should the Smaller Solenoid Move to Induce 2.3V in the Larger Solenoid?

AI Thread Summary
To induce 2.3V in the larger solenoid, the smaller solenoid must be inserted at a constant velocity when it is halfway in. The problem lacks the length of the solenoid, which complicates the use of the inductance formula. The user previously calculated the length of solenoid "A" to create a magnetic field but is unsure if that information is relevant. Additional equations or information may be necessary to solve the problem accurately. Clarification on the required parameters would help in determining the correct velocity for the smaller solenoid.

Homework Statement


Assume the field inside the larger coil (.075m Radius, 1200 loops), reaches the maximum value when the smaller solenoid, (.05m radius, 1200 loops), is halfway inserted. with what constant velocity must the smaller solenoid be inserted to induce 2.3V in the larger solenoid?


Homework Equations



Eind=L(delta I/delta t)

L=[(mu0)(N^2)(A)]/l


The Attempt at a Solution



The problem does not give length of the solenoid, so I am pretty sure the second equation will not work. I can't find any other equations that would seem to help with this problem.

Am i missing something, or would i need more information to do the problem?
In part a we had to solve the length for solenoid "A" so that is would create a magnetic field of .0025T with a current of .13A - which i calculated to be 7.84cm --- but I am not sure if that is going to apply to this part of the problem.

Please point me in the right direction, if i have enough info just given in c, or if I am missing an equation.

thanks

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...
