I personally found the June 2020 to be the most difficult

is there a list of equipment we need to know?? just found out what a set square is and i’ve never used one in my life
Crying HOW????

bro same, i didnt do the practical endorssement so this is just fun. i dunno if you can find a pdf version but im using this book called, student guide AQA practical physics. its by hodder. it seems super useful for this paper

what?

what?
They're everywhere. AQA's had an absolute stinker this year
?? prob doing this on purpose so they have an excuse to raise the grade boundaries as paper 1 was terrible and paper 2 was heavy algebraic manipulation

They're fake then
Do we need to memorise the evolution of a star? Cuz its not on the spec.

It is for astro

No it isn't, we just need to know the path on the HR diagram for our star, we don't need to explain every stage of evolution e.g. from nebula to protostar

Oh really? Wow, I’m surprised by that. Must just be in the textbook for some extra information then. Thanks!
Anyone doing turning points? looking for useful revision resources on it

dunno man i’m struggling
HELP:
A spacecraft passes Pluto at a distance of 12 500 km. The telescope on board has
an aperture of diameter 0.21 m and operates at a wavelength of 450 nm.
Discuss whether this telescope is suitable for studying a crater with a diameter of
approximately 1 km on Pluto.
I did theta=Lambda/D for minimum angular res but idk what to do after that.

You've found your minimum angular resolution, now set up a right angled triangle with half the diameter of the crater on the opposite side and the distance to the crater from the spacecraft on the adjacent side and see if the angle*2 is greater or less that your angle. If it is greater that means that you can study it, if the angle is less you cannot
