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:
