I think it's E then

Ok, it's static electricity that builds up on your body from car seat. So A and B are ruled out. I also think whether can affect the charge, cause if more water /humidity means less electric shock. Is it correct until now?

Maybe the fact that the car is a conductor , so inside conductor there is no charge but on the surface there is?

Homework Statement 1)a student decides to investigate the electric shock she received when she gets out of her car. Which of the following factors least likely to have a significant effect on the size of the shock? A. The material of her clothe B. The distance she slides across the seat when...

Now?

18*340=6120 m Then I subtracted 6800-6120= 680m to find the distance the tornado moved. What am I missing?

Homework Statement http://[url=http://postimg.org/image/f7e6kp0xv/][PLAIN]http://s21.postimg.org/f7e6kp0xv/image.jpg Homework Equations Kepler's laws The Attempt at a Solution I thought the answer will be C : I and II But the solution written (it was my friends book) is B, which is correct?

Ok, I'll review these concepts and then I will try to resolve it.

Then What does that indicate?

But here again the total voltage is higher than voltage in the 3C capacitor. In fact if you add the answers I got for voltage they equal the (90/21) I mentioned before ??

Like how? Cause what I understood from your scentence is that it is the same as what I did

Well now I'm just clueless :/

In 18 seconds it moved 6120 m. So did the storm move 680 m? 680/40= 17m/s Thanks :)

Ok, can I calculate the equivalence capacitance so it is : 21/10 And then by V=Q/C i find V=90/21? Sorry but I am self-studying electricity for a coming exam and I don't understand circuits much.
