Good Luck

Study for the exam carefully. Watch those multiple guess questions-they can be tricky.
Have a great summer & all the best to you in whatever you pursue.

thursday's post

So this is a split scribe cause I believe that someone else is also scribbing. We did 2 worksheet, heres the answers for 37-2.

After we did review chapter 26.

WEDNESDAY JUNE 11, 2008

So, today in class we started off our very productive class by going over the EFFECTS OF CHANGING MAGNETIC FIELDS : INDUCED EMF. If you need to fill in the blanks, feel free to ask anyone for them =).

We also learned about Lenz's Law which basically has to do with electromagnetic induction. We got a sheet to help us figure out how this particular law works. We can use the RHR to help us determine which way the current(s) flow. For example:

Using the RHR, our thumb acts as the "arrow" and our fingers are "rolling upwards" therefore, the currents here are going up.

We also learned about TRANSFORMERS. There are terms that are associated with transformers. These are : STEP-UP TRANSFORMER and STEP-DOWN TRANSFORMER. In a step-up transformer, the primary voltage is less than the secondary voltage, and the current in the primary circuit is greater than the current int he secondary. In a step-down transformer, the primary voltage is greater than the secondary voltage and the cuurent in the primary circuit is less than the current in the secondary circuit.

There is a ratio that goes along with transformers and it looks like this:

We also got a sheet where it is also fill-in-the-blanks and a review sheet which we will go over tomorrow.

PLEASE DO NOT FORGET : TEST ON FRIDAY !!!

[ THE LAST PHYSICS TEST OF THE YEAR LADIES AND GENTLEMEN ]

hello

well im sure the 5th pd class was just as exciting as the 2nd period but man there class is alot more talkative. lol. And how come you talk the 5th pd class on the blog....

So its me again, today in class we looked over a new worksheet and learned a few new equations. Then went on to do 37-1 but not going to show you those answers as the teacher had it done in class. But I will do the 7 questions on electromagnetic induction in a quick fast way.

well that is again if you want anymore detail let me know any I will see what I can do. I need to do at least one more so if no-one else calls tomorrow I would like to do it again. Thanks :)

mondays late post

For Monday all that I can remember is that we reviewed the 2 test given back :) I did pretty good so I was happy. Unfortunately all the answers are written out so theres no real work to be

done but did add a comment or 2. :)

If anyone has any questions concerning the answers let me know and I will try to go through it in more detail.

Space test & Fields test
