THE LINES ARE RADIAL AND PERPENDICULAR TO THE SURFACE OF THE EARTH
g= GM/ ( R + h ) ^ 2..
h is extremely small compared to the Radius of the Earth
So, g is approximately constant

Was the question of 4 marks ??yh it should be
one mark must be for writing change in gpe = change in ke
and then for proving it to be 2.4 and writing wut u wrote = 3 marks
if u wrote the formula yes u got all 4
yh true xDDi think even after such intense discussion, our marks haven't dropped below 80 so it's all good i guess.
yh i wrote thisline are PARALLEL near survace
well they are perpendicular to the surfaceline are PARALLEL near survace
yhWas the question of 4 marks ??
yes but that is the case for all spherical objectswell they are perpendicular to the surface
lol yh sameman i hope i get high 80s thank god bio was easy
well so m defo getting 2changes in height much less than radius of Earth
M1 A1
so (radial) field lines are almost parallel
or
g=GM/R2 ≈GM/(R+h)2
this is what's worth for 2 marks in mark scheme
lol who says itll be high?will I get an A* if I get the following scores:
(31/40 ), (52/60 ) , ( 25/ 30 ) , ( 81/ 100 ) , ( 23/30 )
or will paper 4's high threshold be an issue :/. if it turns out to be higher than 60 ..
nopey'all
i'm a P2 student and i'm flipping out looking at all you P4 kids
Is there anyone who got their hands on the Feb March 2018 series papers?
idkin that
ohh
also, in the specific heat capacity question, i think ive messed that up a bit.
Will I get a mark if I state the formula Q = ML
nope
wont be released b4 17th of May
because the decay constant is big so unstableoh one last qs
wut did u guys write for the last part?
why is the intermediate nucleus so less?
