Well, the acceleration is the difference of speeds divided by the time period.
![\frac{32.4}{0.5}=64.8rev/s^2](https://tex.z-dn.net/?f=%5Cfrac%7B32.4%7D%7B0.5%7D%3D64.8rev%2Fs%5E2)
.
One rev/s is
![2\pi rad/s^2](https://tex.z-dn.net/?f=2%5Cpi%20rad%2Fs%5E2)
, so our final result is
![64.8*2\pi=407.15rad/s^2](https://tex.z-dn.net/?f=64.8%2A2%5Cpi%3D407.15rad%2Fs%5E2)

The Law of the Conservation of Energy is stating that the total mechanical energy is always conserved or in simpler terms, not used or saved.
A because it's the smaller the thicker you just can't have 0 gage
your answer would be The one in the top right corner that looks a bit like this..
When a current flows through coil, magnetic field is produced around the coil which induces emf also known as back emf. When current in the coil is increased, more magnetic field is produced which in turn increases the induced emf.
