You may have noticed the impending inclement weather.
Remember that in the case of a tornado *warning* (not a watch), all university activities are automatically suspended.
So long as it is only a tornado watch, as it is right now, we will hold class today. There will not be a lab, and we will not cover significant amounts of new material as many people may not want to be out in bad weather.
Today's lab is on ac circuits.
Here is the procedure
You will also need to use a Physlet for the prelab questions.
Just a reminer that there *is* webassign homework this week, due Fri 2 Mar one minute before midnight.
This one covers Chapter 19 (magnetism).
Both are online, though the exam solution is somewhat abbreviated at the moment.
Go here, and you will find both.
There is, in fact, a quiz this Friday. Five questions, multiple choice.
It will cover chapter 19. You would be wise to study magnetic forces and probably the mass spectrometer example in particular.
Today's lab will be on inductance and induced EMFs. Here is the procedure.
Several things will be explained in class, so don't worry too much if this doesn't make sense right now. You should also have some time to work on the homework problem if all goes well.
Looking at the traffic on the course blog this evening, it was interesting to see the variation by day of the week. Class periods are obviously Tue-Th:
Most of the site traffic is between 8am-4pm each class day:
This implies to me that 1) most people print the notes just before class (which is fine, just good to know), and 2) the site is accessed frequently during class (no surprise there either).
The geolocation overlays are just neat. Very few *repeat* visitors from odd locations, but a few here and there. Overall, hits from pretty much everywhere. (Note: the size of the dots scales with the number of hits from that location.)
