Chapter 29+30, Problems 7-12

Material to be covered in the last day of class, December 9th.

Due Monday, Dec. 13th, at midnight.

Chapter 29+30, Problems 1-6

These problems are due on Monday, Dec. 13 at midnight. The first six problems cover material that will be discussed in class on Tuesday, Dec. 7th.

The only issue I can see in advance is with #5 (SV8.29.54). In part (a), the question asks you to find the activity of milk due to potassium. Unstated is that you want to find the activity of 1 liter of milk.

Important UPDATE announcement for Lab 10 in PHY 124

In the first part of the lab 10 manual (third paragraph above the Video (introduction to the lab), I just added a cautionary note about NOT using the Excel spreadsheet that may be on the desktop of the lab computer in A-120. (That spreadsheet had some password control in it that may cause you some problems.) You should download the Excel spreadsheet from the link in the revised manual and use that one in the lab.

If you printed out the Lab 10 manual before 3:30 this afternoon (Sunday), what you have will not have the cautionary note in it. Make sure you read the cautionary note.

If you downloaded a spreadsheet before 3:30 pm today (Sunday), you have the OLD one. Delete it and download the new one.

The online manual as well as the pdf one that can be printed out should say at the bottom of its last page:

PHY 124 Lab 10 pretest is now available

The PHY 124 Fall 2010 Lab 10 pretest is now posted for you to work on and submit before the beginning of your Lab 10 section next week. You will find it in the Assignments content area in Blackboard for your PHY 124 Lab section. As explained in the course syllabus, each Lab pretest is worth 35 points. As you will see, the Lab 10 pretest consists of 3 questions. The first is worth 11 points, the second is worth 12 points, and the third is worth 12 points, making the total possible score 35 points. To do the pretest you will need to study carefully the Lab 10 manual and to re-familiarize yourself with MapleTA syntax. Go to

http://www.ic.sunysb.edu/class/phy122ps/labs/dokuwiki/doku.php?id=phy124off:phy124_main_page

and read the instructions there on the "main page". Please also click on and review the

-- "Instructions" link (you've seen this before)

-- "Uncertainty, Error and Graphs" link (and make sure you read the 17 Nov. 2010 message on the PHY 122 Course Blog about printing out this document)

and, finally, the

-- "PHY 124 Lab 10 - "Nuclear gamma rays and decay" link.

No inactive, "red" links remain on the web page. We've come to the final lab of PHY 122 / PHY 124, and it's a nice one.

As you already know, the lab pretests are prepared in the "Maple TA" software environment. You may work on each assignment as many times as you wish, but the link in the Assignments section of Blackboard for your PHY 124 section will become inactive at the starting time of your lab section. Therefore, you should not wait until just before your lab section to begin work on it. If you read the Lab Manual carefully and, there is no reason for you not to earn all 35 points for the pretest. Make sure you read carefully the instructions for each pretest problem. After each problem click on "Next" until finishing the last one, Question 4; then make sure you click on "Grade" in the Maple TA software environment. After you get your grade, you may click on "View Details" to see more about how you did. Finally, click on "Quit and Save".

Good luck!

Prof. Koch
