Sorry i posted this too late, i didn't know i'm supposed to blog last thursday. Well
last thursday Mr. Newman was substituting our class. He assigned our class to answer the " Moving charges worksheet" number 8 to 16 and then we went over the answers. Before the end of the class he gave out 4 handouts for us to do for homework... and that's all i remember.

since someone is chosen to scribe today. i don't have to choose who to scribe next! YEy.

May 22 2007

we started off with question #7 on the test corrections...
next Mrs.K handed out a booklet which she read over to us...I suggest you read it...its very important.
Then we were assigned questions which she also handed out..."Moving Charges Worksheet"
do questions 1-16 but omit 5 6 and 7

the answers to:
1a) Fg is greater than Fe therefore the drop falls.
b) 3.45 x 10^-4 N [down]

2) 4.6 x 10⁶ m/s

3)2.24 x 10^-13 N (down)

next scribe will be ricardo...

This is Lindsay scribing for Thursday's class.

We first watched a video on electric fields. Here are the answers from the handout:

1. charge, potential, field
2. determine height above sea levels
3. field lines
4. hard
5. no
6. down
7. elevation; downward slope
8. E=-v/R
9. direction
10. 1/R₂
11. inverse
12. no
13. constant height above sea lel
14. yes; electric fieldis perpindicular to the surface
15. 10 000
16. ionizes the air, electrons accelerate
17. ability to do work when electrons flow; volts
18. Ep=qV
19. charge in chemical form
20. charge, energy electrical field, foce, volt/potential difference

We got another work sheet. Here are the answers:
1. loss PE = gain KE
2. force; distance; W=Fd; increases; equal
3. potential; voltage
4. 1V
5. 12J
6. 5000 V
7. 5000V
8. 5000V
9. .005J
10. charge

We did a lab and hand that in ASAP

We also got more handouts and a worksheet for long weeked homework!

next scribe is...caroline

HEY HEY HEY! Well for those who missed today's class we received a couple worksheets, which pretty much is about ELECTRIC FIELDS. We also talked about the differences between electric force and electric field, also the differences between gravitational field and gravitational force. Also a handout of Electric Potential. That's what we pretty much did in class today. SO FOR THE NEXT SCRIBE........I PICK........



LINDSAY

Heeey guys!!! It is Linger here, and I am your scribe for today and yesterday's class. Anyway, let's begin!!!

Yesterday was the last day of presentations for our projects on Space Exploration. We had Mark present his but due to technical difficulties, others could not present theirs. If you haven't already presented yours, all you need is a group of 5 volunteers to watch your presentation during a lunch hour... it's better late than never! We also had the worksheet called ELECTRICAL FORCES. And that brought us to the end of class. Homework was to finish number five.

In today's class, we corrected the worksheet and Ms. Kozoriz explained how to do number five. We also got a booklet about Coulomb's Law. The first page was based on One Dimension. The second page was about Two Dimensions using equilateral triangles. The third page was about Two Dimensions using squares with indvidual forces and last page was Two Dimensions using squares and adding the forces. The booklet was pretty straightforward. It tells you what to do step by step in certain situations. Remember to convert the measurements to meters if it is given in centimeters. Also, remember to square the value in the denominator!

After discussing this booklet, we were to read pages 415-420 in the red textbooks. For Practice, do problems 1-5 on page 420. Questions 15 and 16 on page 423 are to be handed in for marks and in order to write the unit test.

Well that is it for me. For further help or explanations, make this blog your friend and scroll down to the slides that was posted for today and/or yesterday's class. Anyway, the next scribe is none other than....

BAAAALEEEE!!!!
