i did these from memory so may have missed out on a few qs pls mention them in comments

kinematics

graph stright line at y=8 for athlete

constant acc for cyclist

3m/s^(2)

40>37.5

body at rest remains rest/body in motion remains in motion unless act fo external force

moment

anti=clock when at equlibrium

520

1.2

work energy power

16000 J

vaccum has no particles+no convection+less heat loss

white+shiny cus poor emitter

4.5x10^(9)

2.6W

pressure

force and area

upwards/downwards

Solar energy/wind/tidal etc

dont rmrb others if there were any

waves

they shoudl js look like a converging and diverging lens and normal drawn right ig

the image was inverted, on opp side, real? after drawing three rays

freq inc wavelength dec from radio to gamma

electricity

work done dirving charge across compelte circuit vs one component only

V=IR

3.6

133

dec, inc, inc, inc, dec

magnetic induction?

4 lines goign through the solenoid as well left side was north pole

cuts the coil/emf produced+ current produced as well

nuclear

beta: higher ionization/ low penetrating

geiger muller tube

random/spntaneous

10

50

for the why choose low half life over long i wrote medical reasons idk

space

weird ass circle js made it go through points x and y and then also bw the venus and mars orbit where it was v close to sun

mercury closer to sun+gravitational attraction highest?

fusion

graviational (inward) and radiation pressur eoutward sm like that in one of the answers

sun becomes red giant-->whitedwarf-->black dwarf

this is acc a joke us science kids litr had all the worst papers b2b math and bio in a span of less than 24 hours are we fr? then physics on monday and math p2 or chem p4 bhi b2b. and were basically done w all the hard papers and have like a whoel month left for p4s and p1s which need a lot less prep this is so unfair to us cus we would be much better off preparing for high weightage papers in the middle. im js glad chem p1 is in the end it scares me the most.

i understand sara saal parhna hota hai and my grades fluctuate bw a* and b but liek bro this time is so crucial and can make the most diff to ur grade

can anyone tell me how weightage affects our grades cus if my p2 which had 50% wt didnt go well does it mean i can still score a grade by doign well in p1 or 4 cus they have such little weightages it seems impossible. how do these weighages work

im not worried ab it cus Ive been doing well in school exams but I havemt studied at all since like the day before my em mock and all i can thnk of is reading notes and stuff or doing pp, any other advice or tips for em, I REALLY want to score 100%, any advice would be muchh appreciated!

ok so i did land at 5,7 but i did not do the simultaneous eq way but instead made like table for x and y values will i get makrs deducted (nfww=not from wrong working wala reason)
