gods gon bless you if you tell me what was supposed to be done in paper 51 question one
ignore = 10 years of bad luck ffs

DID SOMEONE GIVE PAPER 51 CAN THEY WRITE DOWN POINTS THAT WERE SUPPOSED TO BE WRITTEN IN QUESTION 1 AND WHAT DIAGRAM YALL MADE IM LOSING MY SHIT
The time was 12s for sure, I have checked that question with my teacher. Also just to clarify, you don't lose a mark for every answer that has an incorrect no of significant figures. You only lose 2 marks at max for the whole paper if you have written answers to an incorrect no of significant figures(throughout the paper).1888.8 and the time was either 6, 9, or 12 (ppl are arguing over it)
did u also do the thing where F vs V would give a straight line and then F is dependant on VHey .. I did p51 I also found it extremely confusing .. I drew a retort stand with a clamp holding sphere T and it should be of the same height above the bench .. for charging the sphere .. I connected the positive terminal of the Alternating power supply to the sphere and I connected the negative terminal to a metal object so that the circuit is complete (working) .. then found the voltage across the alternating power supply using CRO .. and for the force I found the mass of sphere S using balance and multiplied by 9.81 ....
It is kinetic energy.What was the angle of momentum question, i got 60 something and what about the question about What type of energy Y gained
Yes that’s correctdid u also do the thing where F vs V would give a straight line and then F is dependant on V
Yes bro, frequency increased. That was a bit of a trick, though it could've easily been noticed.in the question related to doppler effect , even though the source was going far from the observer but its velocity was decreasing .. when we considered till 8s as mentioned in question. so should'nt the frequency increase
the distance is constant. i forgot to write the F= mg technique but i did write the relationship correctly. i also wrote about letting the sphere charge and reading on top pan balance to get constant to make the final reading. told to measure the diameter of spheres properly so that the distance r is accurate and proper. anything else?Yes that’s correct
it'd be nice if someone answered this lolFor paper 52, did we have to take 10^3 for the nR to calculate gradient?
I did. and I think we shouldit'd be nice if someone answered this lol
well i got the gradient wrong :/ yepp i took a bad startwhich parts did u mess up?
In the graph, did the x-axis not include 10^3?I did. and I think we should

well thats okIn the graph, did the x-axis not include 10^3?
Oh god, I messed up :/
yeh the whole paper i kind of couldnt complete on time. Q.2 was also on the tougher side. i drew the line of best fit and stuff. what was your gradient .What did you use to measure diameter ?? I used vernier caliper .. how was Q2 did u finish on time ?
I hope it won't be like 43,44. How did the people in your school feel? Are you taking A2 as well ?S17 was surely tougher than s18! S18 had standard questions with little trickery, but s17 had a few new questions with different styles. Thresholds are expected to be 40-42 for S18.
Oh but shouldnt other particles also gain K. E and it didnt lose mass though since mass number was constant?It is kinetic energy.
