Physics - desperate!

<p>Well, I never thought I’d do this, but here I am asking for homework help on CC. I have a physics lab due tomorrow, my partner is as clueless as I am, and I can’t reach anyone else remotely helpful.</p>

<p>That being said, here’re the questions I need help with:</p>

<li><p>Name at least one advantage of using residual charge by induction rather than by conduction. Assume in both cases that you’re trying to charge a metal conductor starting with a rubber rod and bunny fur.</p></li>
<li><p>Is it possible to effectively charge an insulator using conduction? Explain.</p></li>
<li><p>In the absence of a true ground, would a car frame be an adequate ground? Explain.</p></li>
</ol>

<p>For number 2, I think my teacher said something about how it’s always possible to charge an insulator, but I’m not sure if they can be effectively charged. For number 3, I’m leaning toward yes, since it’s made of metal and can therefore absorb/give up a whole lot of electrons.</p>

<p>That sucks.</p>
