LOL
Thanks anyways though. Yea, I figured it had to do something with volume, since they gave the mass. If you have the book, they listed the density in there, on page 274 if i remember correctly.
I did something completely different, and way more difficult than what you listed lol. I didn’t know the length x CS area = volume.

For all you zengers…
i never did any of my HW, never went to class, and got an A…
So in my experience HW is meaningless, in fact you can just enter random shit and still get credit for it lol. This is assuming you dont actually care to learn physics…

Alright, I’m stuck on this one. I think I know how to do it, but the computer doesn’t think so…
b) If the total power supplied to the circuit is 8.00 W, find the emf of the battery.
The total resistance is 7.99.
Edit: Nevermind got it
