I took mine back in January, but I do remember a bit of orgo and physics. There are some physics formulas you just need to commit to memory, but it's not a very long list. I think you can probably find a list online somewhere. However, from what I remember, most of the time the passage either gives you the formula, or gives you enough information to figure it out. I highly recommend getting familiar with dimensional analysis, it's a lifesaver!
They are not expecting you to ever have seen either equation, they are expecting you to know that Watts can be obtained by N*(m/s). The same can be done for the other equation you mentioned. Units are your best friend on the C/P section, I just took the real deal and my C/P was almost all Physics and Biochem. Best of luck on the real thing!
The units for conductivity are S/m. A siemen (S) is defined as the reciprocal of an ohm (ohm^-1) so it can be seen as having the units of ohm^-1*m^-1 or 1/(ohm*m). The units for resistivity are ohm*m, therefore it follows that you would have to take 1/resistivity(ohm*m) to get conductivity (S/m). I don't have access the FL anymore but that is what I can remember about the question, it is not an easy one and I think most people would miss it. If you post the question I can see if there is a different way to solve it. Don't get caught up by this type of question on the real deal, probably one to skip if you don't know the units for conductivity. Best of luck on the real deal, remember your well prepared and going to do great!
