You can't convert km/hr to m/s^2.

Yeah, I think I'm beginning to understand it better. And no, I haven't learned the Lorentz transformations yet, I will be learning it next lecture. Hopefully that will clear things up even more. Thanks.

Sure it is. By doing it the right way, the formula is derived and by doing the wrong way, it isn't. I want to know why the right way is right and wrong way is wrong.

Well sure I can just memorize formulas but I want to understand where they come from.

Homework Statement How fast must a meter stick be moving if its length is observed to shrink to 0.5 m? The Attempt at a Solution A meter stick moving at speed V to a stationary observer is the same thing as a stationary meter stick and an observer moving at speed V. Lproper = Lp = 1 meter...

Ok, thank you.

8/18 If it's in parallel what's the formula for finding the total Resistance?

18 right.

V=ir ?

I don't know there's supposed to be a picture but it doesn't come out. I think it would be series.

Yes.

I just don't know how much is lost when it goes through each resistor.

Yeah I was looking at 21-2
