Exercises from today's lecture

We reviewed three exercises today from Ch. 21, #8, #10, #24. I scanned them onto PDF and parked the PDF file in "Go to the doc cam," with the small citrus battery icon. Yay.

Homework T-101, come with me if you want to live.

You can get started on Homework T-101 right now, and try to follow Arnold's advice: "Come with me if you want to live."

It is in Webcourses now.

Homework #909 ready to go

You can now look in Webcourses for 9 questions in Homework #909.

Don't forget the study assignment before attempting the HW:

1. Read pp. 430-433, remembering the concept that voltage is like water pressure.
2. Fig. 21-1 on p. 428.
3. And if you want to skim the rest of the chapter on currents and circuits, you can get a headstart on Monday's lecture.

Homework available after lecture

Homework 14 will be available after lecture today, and it will be due on Friday at 3:30 PM.

Exam 3 breakdown sheets are available now.

Pick up your exam 3 printouts from Meg or Ashton, and then look over the breakdown spec sheet for your exam form, A, B, C or D. The breakdown sheets are now ready as PDFs in Webcourses.

SSG points are now up.

If you took part in special study groups (SSG) last week, you can now look at the gradebook and see your two bonus points. YAY.

Homework and CPS pointage totals to date

Right now there are 91 points available through the thirteen homework assignments.

Via CPS sessions, there have been 67 points available.

If you look at your gradebook lines, you can see your totals for CPS answered, CPS correct and homework, and then you can calculate your percentages, based on 67 for CPS and 91 for HW.

P.S. According to the CPS scheme,

1. if you have 57 CPS answered you would get all 30 CPS points, based on having 85% answered, and
2. if your "CPS correct" is 51 or more, then you would get 4 bonus points on top of everything else.
3. IF today were the end of the semester.

But we still have some CPS and HW pointage ahead, so do not count your chickens just yet.

Linsky files are up to date.

I just uploaded Linsky Files for Friday's and today's lecture, plus CPS pointage.

Students present in Friday's class will also notice the CPS mega-bonus points from that session.

Excellent.

Homework 13

Homework #13 is now ready in Webcourses. It is due on Wednesday at 3:30 PM.

I also recommend that you try exercises 6 and 14 from the back of chapter 14.

Exam 3 grades are UP, HW 12 ready

1. Exam 3 scores are now up. I was very happy to see some nice improvement.
   
2. HW 12 is running, and it requires some extra reading in chapter 13. It is due Monday, 3:30 PM.

If you want to read ahead, start scanning chapter 14 about entropy and heat engines. Hurricanes are enormous heat engines.

Have a great weekend.

Thermal properties today

We will be working a homework set, HW 12, this afternoon, which requires some reading on your own in chapter 13 on these topics:

1. thermal conductivity
2. thermal expansion

Excellent.

SSG: Last chance at the O.K. Corral

Last Chance SSG
There is one more late-breaking special study meeting at noon at the library, led by Matthew Kovach. If you missed out in the signups for yesterday's groups, go sign up for Matt's!

Chapters?

In case you are wondering, here are the chapters we will cover in exam 3:

11. Structure of Matter
12. States of Matter
13. Thermal Energy up to p. 254.

We will cover the last few pages in chapter 13 on Friday.

SSG is now open for everybody!

If you were not in the first group, you will now be able to snag a spot in SSG. Signups are now open to everybody. Look for the blue SSG icon on the home page.

SSG holdup

I am working on SSG signups, which appear to be snagging somewhere in Webcourses. I had to ask the Webcourses admin for help.

Stay tuned and be ready to move quickly. I will probably extend the signup availability for the first group past noon, but stay alert.

Linsky Files up

OK, the last few Linsky files are now UP.

21. about the submicroscopic momentum and kinetic energy interactions that form the basis of the ideal gas model.
24. about a submicroscopic kinetic energy brain-burner and the Kelvin scale
25. about pressure and volume of bubbles #1 and #2 plus some brain-burner action on subterranean rodents, i.e., moles and Avogadro's number.
26. pressure differential in bubbles
27. water column, Bernoulli principle and Greenland vs. West Africa.

Trouble

It appears that there is trouble on the Webcourses channel tonight. I cannot modify groups in any way, including SSGs!

Glitch fixed; now SSG is ready for signups

OOOPS, a glitch in SSG was keeping it invisible to everybody. Now it is fixed, so it should be visible and available for the first group to sign up.

AND, there is one more group, so a few more slots open.

SO... go take another look if you want to sign up!

SSG signups will begin at 3:30 PM for limited group.

The signups process will begin for special study groups today at 3:30 PM, inside Webcourses, for the first group. Look for the blue SSG icon on the home page. If you are not in the first group, you will not see the blue SSG icon today.

The first group will have until noon, Tuesday to find a group and sign up. After that, I will open up SSG to everybody, if there are still spots available. Tuesday afternoon, the blue SSG icon will be visible to all.

Sorry we cannot get more of you into SSG, but we did not have many students volunteer to lead this semester.
