guys for s2, do they cut marks if we havent written the reason why we have used normal distribution as an approximation to possion ? ( i think i forgot to write lambda > 15 , so normal ). but the answer is correct

O bas bas, you need to be smart to do well in such subjects too!!! You don't just get 1500+ in sats just like that...

some people got the value 5.20 for mew instead of 0.577. What they did was reverse the direction of P such that now it acts down the plane. So the two simultaneous equataions become P(min)+20gsin(60)=20gcos(60)mew and P(max)=20gcos(60)mew+20gsin(60) and then P(max)=2P(min).. Did the question specify the direction of the force P or no?

It cant be that large...if it is 5.2 it should be on something like sandpaper

someone tell the correct answer for power in question 2 i want to confirm too

I got mew 5.2 I know its wrong (beacause mew is usially between 0 to 1) can anyone point out where i went wrong? Plus How much marks can i expect for this question?

Not sure what went wrong, would have to ask my teacher about this, so if anyone has got pictures of the paper please do share them(ask your exam officer to take photos from the extra copies CIE sends, pls). You can expect to lose 1 mark for the wrong answer for sure, and possibly 2 marks for not showing one of the correct scenario. You should get around 4 marks still provided that you showed your working in full.

Btw Check this out Friction coefficient can be as high as 21 provided you conduct the experiment in VACUM which was'nt mentioned on the paper ...BUT it did'nt specify of air Either(JK...lol)

LMFAOOO XDDD
This made me slightly less depressed about tomorrow's Chemistry
The steps you took to prove your point XDDDD

Guys what's the answer for the distance question? the calculus question in M1?

i got 20

 

[hellodjfos;s'ff]

Yup 20 m here too

man i did sooooo bad in maths this year....i wish i get the chance to resit it in ON...Man stress can kill someone's confidence, like my level in pure maths was sooo good that i excpected to score a full mark (that's how well i was in pure) but then i saw the yellow paper and got shocked then i started stressing and ended up doing some random shit....mechanics it was my fault for not paying it much attention..sigh, a hard lesson learnt the hard way

 

[Mistar-Kigi]

Okay fellas! Now I know this question has already been answered but I really need opinions of more than just 1 person. My value for mew was about 5.2. How much marks am I really expected to lose here. The question was worth 7 marks just so you know.
