Can anyone explain how one would normalize data from a lab? We just completed the lens equation lab in class and part of the analysis is to include "normalized" virtual object data in the graph. There are only 4 measurements taken. Any feedback would be great! :shy:

How do you find the total energy received by an EM wave in a period of time? I tried U=c * Area * time *power..but this doesn't seem to be right...any suggestions?

I can't figure out the molecular geometry for C2H4Cl2 (dichloroethane). The e- pair geometry seems to be tetrahedral, but I'm not sure for molecular. Any help?

I have a question that piggy backs that problem...what would the angular velocity be whent he rod is vertical? I know that mgh=1/2Iw^2..but how do I get the potential energy of the rod?
