Answer:
C
Explanation:
The answer is C because if you look at the 1 hour mark it shows 10km
Answer:
The voltage across the capacitor = 0.8723 V
Explanation:
From the question, it is said that the coil is quickly pulled out of the magnetic field. Therefore , the final magnetic flux linked to the coil is zero.
The change in magnetic flux linked to this coil is:

= 0 - BA cos 0°
![\delta \phi =-BA \\ \\ \delta \phi =-B( \pi r^2) \\ \\ \delta \phi =(1.0 \ mT)[ \pi ( \frac{d}{2} )^2]](https://tex.z-dn.net/?f=%5Cdelta%20%5Cphi%20%20%3D-BA%20%5C%5C%20%5C%5C%20%5Cdelta%20%5Cphi%20%20%3D-B%28%20%5Cpi%20r%5E2%29%20%5C%5C%20%5C%5C%20%5Cdelta%20%5Cphi%20%20%3D%281.0%20%20%5C%20mT%29%5B%20%5Cpi%20%28%20%5Cfrac%7Bd%7D%7B2%7D%20%29%5E2%5D)

Using Faraday's Law; the induced emf on N turns of coil is;

Also; the induced current I = 




The voltage across the capacitor can now be determined as:

= 
= 0.8723 V
This should help you with ur question
