What is the open circuit output voltage, Vout?
Estimate the short circuit output current
Can someone explain to me how to do these.

I need help with this: http://img716.imageshack.us/img716/3262/unledewk.jpg
I know that I need to create an extended free body diagram and I understand how to get all the equations from the diagram. BUT I don't know what to do when it comes time to use torque and find...
So does that mean I find v by means of conservation of momentum, and then use omega = v / r to find the answer? The reason I'm confused is because at the note at the bottom of the question, it says treat the door as a rod rotating about its end, which is a hint to use Inertia = (1/3)ML^2...

For a, I got omega = 18.63 rad/s by using methods of conservation of energy. Can someone tell me if I did this right? If not, please help me out! To be honest, I thought I had to use...

What is the RMS voltage of the top wave?
Homework Equations
RMS... root mean square
The Attempt at a Solution
If I'm right, the peak voltage is 1 V (gotten from 2 * 500mV). Square of 1 is 1. And there are 4...
