How do we solve Physics problems? In this video I look at what I think is one of the most important high level skills in A Level Physics - staying calm and breaking down a problem into individual easy smaller problems.
As an example I look at problem 22 (Astrophysics) from OCR Modelling Physics 2022.

Please note that this is not an official solution, I am not affiliated with the exam board. Please let me know if you find an accuracy or a better way to approach the problem.
This is a problem that can be used for revision for all exam boards including OCR A Level Physics, AQA A level Physics, IB, Cambridge International CIE 9702 syllabus and similar courses such as AP Physics for example.
To solve this problem we use many concepts such as Stefan Boltzman's Law, Wien's Law, Stellar Evolution, etc.
