Im relying on the extended responses being on models of atoms or the light ones, know barely anything for the points like how radiation turned to matter

honestly probably mod 6.

ikr pray for a model of atom and let me spit 9 marks of thomson rutherford and bohr lol

mod 6 probably requires the most understanding i think just because of lenz law which took me forever to understand

Im fine with anything besides standard model of matter, transformation of matter to radiation and special relativity

Well that’s a good portion of mod 8 I’d probably revise that

 

[Skkkkkkkkkk]

guys what module was more focused on last years exam u reckon

i think there was a bigger focus on mod 7/8, however last year they didnt ask about light, the atom, standard model or big bang which worries me cause they might throw it at us tomorrow. also there was a lack of motors/generators for some reason since most trials focused on that a bit

Nah i know like the basics but probably not indepth enough to do like a 9 mark question on

can someone briefly explain how particle accelerators are evidence for standard model?

Particle accelerators convert kinetic energy into mass via collisions, the mass created being quarks, hadrons and leptons (and combinations of such). So it’s direct evidence for the standard model

what are the drawbacks of the stand. model anyone?

OOH ALSO what equations do we need to derive?

Drawbacks of the standard model mainly revolve around lack of explanation of gravity and why it’s weaker than the other forces.
Equations to derive, I’d definitely memorise derivation of Bohr’s angular momentum formula, as well as maybe Torque on a DC motor and maybe relativistic ones, although they are easily explained with the thought experiments.

you derive every equation that isnt on the formula sheet (off the top of my head itd include orbital velocity, escape velocity, total energy)

those are all p standard derivations tho, is that all?

isnt the torque equation (=nIAB sinx) on the formula sheet or is there another formula?

 

[homeworkatedog]

Since u lot are all pretty smart, anyone know how to solve Schrodinger's differential equation?

do we need to know?? Cos i have no idea i only know it looks kinda like a cat

I didn’t know it was on the reference sheet well guess you don’t need to derive it. In this course, as long as they don’t specifically ask you to derive any formula, you can quote any memorised formula as if they were given to you, e.g total energy of a satellite, escape velocity, velocity on a banked track

Please do your thing and manifest as much mod 5 and mod 7 as possible for all of us

What textbook you have?

manifesting no mod 8 while we're at it

What you mean mod 8 extended responses are the most straight forward
