IB DP Physics SL Nov 2019 Paper 1 (Part 1, MCQs 1-10) 

Hi All, someone wrote that the answer to 4 should be (B), but that is incorrect. The correct answer is (C) as shown in my video. For some reason the official markscheme is incorrect :) Sometimes that happens. Every now and then a question is actually removed completely because it wasn't phrased correctly. Always see a mistake as a learning opportunity!

ur a lifesaver !! thank uu

Thank you!

Hello Sir, I don’t quite get question 8. How did you get 15E/16?

didn't really understand how you got 16 for question 8

Hello, for question 5, how do you know to assume that the frictional force is negative and weight is positive?
