This was very helpful, thank you. Just wondering why the uncertainty wouldn't be 1mm when you are measuring the length of card, as technically you are taking two judgements of 0.5mm when using a ruler to do so?

I have the exam tomorrow what would you suggest doing between now and then? I feel like I don’t know much.

Can we get a face reveal pls 😩

For anyone confused on question 18 (19:40), N is supposed to be 9.5 x 10^10 nuclei, by converting the half-life of 1600 years into seconds, not 3001 as shown in the video. The question is from the Edexcel A Level paper June 2018, the mark scheme is cdn.savemyexams.com/uploads/2019/09/Markscheme-ALevelPaper2-June2018-A-Level-Edexcel-Physics.pdf

Hi, for level 3 I get the same results as you up untill the end answer. When I input the values of 1/2*(9.81)*(0.91)squared, I get an answer of 4.0618305 rather than 4.09. Ive checked to ensure all that Ive typed in is correct and keep getting the same answer, any ideas what is happening here?

Thank you. What paper is the question in 13:30 in?

There is no parralax in the stars from earth, scientists claimed to have seen parallax from a spaceship that took photos after lining up to 50 other stars. As for finding the distance, size or speed of any bodies in the solar system/galaxy/universe, one would need to know at least the distance and size of at least 2 of said bodies. No one seems to be able to explain how they come up with the first distance of a planet without knowing any other distances.

Sir which textbook do u use

How does the number of neutrons lead to less binding energy per nucleon if they have a higher mass? Shouldn't that be the opposite - since Neutrons have a higher mass they will tend to contribute more to binding energy?

This is AMAZING - exactly how my School teaches it. I tend to prefer watching videos when I learn as I can better understand it then. However, in School - I tend to miss out on minor details - so watching videos like these are extremely helpful.# (liked and sub)
