wednesday, june 15th

sorry for the late scribe guys! for class we just did review and handed in our worksheet 'the contributers in determing the speed of light. dont forget that our exam is tomorrow morning, june 17th at 9:00 and also just a reminder dont forget to bring your exam slips. if you didnt get your exam slips yet, please see ms. k :) good luck everyone and study hard!

June 14 2011

At the beginning of class we corrected questions in The Nature of Light: Part 2 Green Booklet. If you weren't able to get the answers then see Ms. Kozoriz or anyone else in the class. After that, Ms. Kozoriz handed out our exam slips for FRIDAY, JUNE 17 @ 9AM (remember our exam is only for 2 hours).. For the exam, you'll need a ruler, protractor, calculator, a pencil/eraser and BRAINCELLS :). If you didn't get your exam slip then see Ms. Kozoriz ASAP. For the rest of the class, we did our reviews and/or our research on the scientists.

PAR will scribe next ..... dont forget to study for the exam!! :D

Corpuscular Theory, Wave Theory & Determining the Speed of Light

Today we started off the class by correcting the problems in 'The Nature of Light: Part 2 The Wave and Particle Models of Light' booklet that we were assigned the day before. You can find the answers directly from the salmon book from pages 3 through 18, or ask a friend!

Next, we were given two worksheets "Appendix 2.4: Chart for Evaluating the Models of Light" one of which was yellow and the other pink. The yellow sheet should have the model as "Corpuscular Theory" or "Particle Theory" if you do not like using the word corpuscular and the pink sheet should have the model as "Wave Theory." We went through the supporting arguments and counter-arguments for each phenomena for the Corpuscular Theory, which you can also find the answers within the salmon book. We were then given 15 minutes to finish the pink sheet and find the supporting arguments and counter-arguments for each phenomena in the Wave Theory. We also corrected this. (All answers are found in the book if you read pages 3-18 the previous day!)

The next worksheet handed out was "BLM 2.10: Contributions to the Determination of the Speed of Light" which should be handed in on Tuesday, the latest. The worksheet is straight forward and you can find the answers to the boxes on pages 9 and 10.

That was all for today. Have a great weekend everyone! Don't forget to get started on your exam review..the exam is in SIX days!! Friday, June 17th 2011 at 9AM sharp!

The next scribe will be Jaksen

June 9 2011

Hello! Today we got our tests back, you can make corrections and hand
it back in to get a bonus mark. The class was used as a work period
and Ms. K assigned pages 3-18 of the pink booklet to read and
complete questions 1,3,4,9,10, 11, and 12. See everyone tomorrow!

Next scribe shall be Pink!

8 more days till the physics exam!

All we did for today’s class is answered the Review Problemzz on the Board!

Review Problem Answer Key!

1. Opposite attract likes repel

2. 2. Magnet polarizes the object & attracts the electrons of the object

3. - Temporary magnet

- Nail paperclip

- Tiny loops of current within the substance

4. Domain are no longer aligned

5. It unaligns the magnetic domain weakening the strength of the magnet
. . . . . .

6. S-----------------------N
x x x x x x

7. -Aluminum
-Cobalt
-Nickel

8. You cannot isolate them; because the magnetic domains only flow in are directions. This means the domains would remain uncharged even after breaking it in half.

9. To determine the polarity by using the second right hand rule, curl your finger around the loops in the direction of the conventional current, thumb points toward the North Pole of the magnet.

10. Thumbs à Flow of current

Finger à Magnetic field

Palm à direction of force on wire

11. South Pole, because the north of a magnet is attracted to the magnetic South

12. Magnetic declination is the given location between the magnetic North & Geographic South. Also called the angle of declination.

13. An electric Field surrounds a stationary electric charge.
A magnetic field surrounds a moving electric charges as well as an electric field.

14. B = Fb/IL
0.20/0.10*5 = 0.40T

15. F=BI

= (115min)(5.0x10^-5)

= (4.00x10^-2)

= 2.3N

16. FB = ILB

0.040 = (2.0)(0.1) B

B= -20T

17. Magnetic Field = Fb/IL

Fb=BIL = 0.900T x 8.00A x 0.500m = 3.60N

For does PPL who did not show up to Mrs. K class and don’t understand how we got this answers, talk to Mrs. K before the third Period end. Have a nice half day 2morrow. Better to review Magnetism and Electromagnetism 2morrow because Wednesday we have a test for this unit.

Friday, June 3rd/2011 Magnetism and Electromagnetism V

Yesterday in class since most of the students are missing, Ms. K went through p 35-36 with us. The rest of the period is working period. A reminder to all of us, hand in the lab next Monday.

Wednesday, June 2nd/2011 Magnetism and Electromagnetism IV

Today in class we had to finish pages 35 and 36 if we were not done them, as they were assigned yesterday. We were also supposed to do, problems 6 to 17 in our Magnetism and Electromagnetism booklet which is on page 39.

The next scribe will be whoever wants to be the next scribe.
