Thank you so much for these videos. i thought i was going to fail physics due to my shitty physics teacher but you saved me
I'm so happy to help you out! Cheers, Mitch
Real
Your a life saver ❤
Thanks!
Just a couple of questions:
1. Are we supposed to memorize the HR diagrams including the luminosity, temperature, and solar radius for the ib exams?
2. How will the HR diagrams be used on the exams(like questions that have estimated answers)?
Good questions - you don't need to memorise HR diagrams, so you'll be given one if you need it on the exam. However, it's nice to know what goes on the axes, and a few important facts like the path of a star on the diagram as it ages, as well as the fact that the colour on the x axes helps you to know luminosity on the y axis. You should know where the main sequence stars are (the zig-zag along the middle), and that a main sequence star is burning hydrogen to helium through nuclear fusion.
As an ib course (everything sl) student the paper 2 was so much easier than paper 1 and 3
I'm glad you finished! :)
Quick question -- do I need to watch the last four videos in this series when prepping for option D of physics SL?
i don’t think so
Depends if you're an SL or HL student. If you're HL, then you need everything in this playlist.
I love you
Awww, thanks, right back at you! :)
