5 Days to Go

As the days passes on the more we are press on time to complete everything for school and getting every thing out of the way for the upcoming exams. For today's class we went old school and went over the worksheet with the magnet and the coil of wire. Remember the charge of the coil at the end where the magnet enters or come out of is the opposite of what you think.

Example:








Then after we went over some questions on a different worksheet with ratios of voltage and coils. Finally for review for tomorrow's test and Monday's exam do questions 44- to the last last question on the exam review and good luck every one!

Again, no one seemed to scribe so I guess I'll do it.

Today, Ms. Kozoriz found out that for the last two days we technically didn't learn anything new, since we did Sudoku with one sub and just went over answers with another.

So, Ms. K popped in a DVD so that we could learn more about how magnetism and electricity are related, and how electricity can be converted into magnetism and vice versa.

From there, we were handed a worksheet that had to do with transformers and told to finish the worksheet that had seven questions that use the equation that deals with Electromotive Force or Voltage Potential Difference.

The potential date for the test is either Wednesday, if Ms. K believes we're ready, and if not, Thursday.

Next scribe for tomorrow will be Tony.

Hello, no-one seemed to scribe for today so i guess i'll take the liberty of doing it, today in class we had a sub yet again, and we recieved so more sheets, as usual, and we then corrected Chapter 37: Electro magnetic induction and Chapter 25 Study Guide. Our Assignments/Homework for Monday is the Grade 12 physics worksheet on Electromagnetic Induction and finish the combination circuits sheet.

The answers for Chap. 25 and 37 are:

Hello Everybody,

Kamil reporting in, sorry for being a day late, its a long story.
On thursdays class we had a substitute, he gave us sudoku puzzles for an obscure reason, and said if we finished them we might get an A+ for the whole course, yeah and legless man can sprint. After words we recieved a combined circuits work sheet and a chapter 25 fill in the blanks sheet.

A very Cold, Cold Day

Hello everyone, Rojuane here to scribe.
I almost forgot to scribe, but I remembered!

Today a good class. We basically went over the worksheets that were given a couple of days ago. The answers to the Compound Circuits are found on the blog just below my scribe. The Power in Electric Circuits worksheet with the 4 diagrams were assigned by groups to find the Current, Volt and Resistor. Then that's when the bell rang.

Here's stuff to know about a series circuit:
Current is constant throughout the entire circuit. For the individual potential drops add up to the total potential drop.

For a parallel circuit:
Individual currents add up to the total current. Potential difference is constant across all parts of the circuit.

Here are things to REMEMBER:
Test on Electric Current: Tuesday, January 20th, 2009
Physics Exam: January 26th, 2009 - AFTERNOON

Make sure to do your Physics Exam Review to do well on the exam and to refresh your memory!
Good Luck Everyone!

Last Blog! YAY! Sorry for the late blog!
Kamil, you're next.. so you better do it!
Off to bed for a very early doctor's appointment,
Goodnight! :)
