I think the easiest way to relate this to syllabus may be to straight up say advances in physics is the basis for advances in modern technology. I believe from the syllabus this comes under PFA H3 "Assess the impact of particular advances in physics on the development of technologies".
In this case you have some good options:
- Photovoltaic Cells leading to Development of Solar Cells
- Eddy Currents leading to Electromagnetic Breaking/Induction Heating
- Superconductors leading to maglev trains
And you can use a couple of these to your advantage to really flesh out a response. The syllabus loves to ask questions along these lines, as well as stuff that comes under
PFA H1 "Evaluates how major advances in scientific understanding and technology have changes the direction or nature of scientific thinking".
In any case I'd recommend for this question picking two of the above examples (Personally I'd choose photocells and eddy currents since they are most intuitive to me), go through with explaining the physics behind each with relevant equations etc. and then simply linking this to the technology chosen. With this sort of format filled out enough I think that would do it for 6 marks.
