wasn't that the 2 marker, the 4 marker was the force in ring X no?

Yup he's correct. Gonna comment

What did people say for the current in the primary coil question?

 

[Engineer_192931]

u basically just had to show VpIp = VsIs I think, and current increases cos u have more bulbs

I said current decreases cuz there's more resistance due to the bulbs

 

[carrotsss]

Could you explain why this is? (Clearly I have a hole in my understanding of EMF)

idk it just is I remembered from some other question, you can look it up if u want confirmation

band 6 guys?

What did everyone think on the last question part b which asked to find kinetic energy for 4 marks, i did total energy - potential energy equals kinetic energy but i dont see how that should be 4 marks (show potential equals 1.6 something Joules)

I think I explained it wrong then, but I swear it said increase current in primary when they asked question

I think it didn't clarify increase or decrease, just that it changed maybe

I got 5 marks. I found the vertical component and the horizontal component found time, and found distance from launch, but not distance from the new updated position

I got the distance to be 4 meters is that correct?

band 6 guys?

possibly

I think I'm right actually cos it was parallel circuit not series

Was that voltage question just 40?, I thought it was wrong but legit forgot to go back and check it. Ps how many scientists did y'all do for the 9 marker

I did Thomson and Millikan and went in to large detail and mathematically showed what they found. Plus I spoke about the discovery of quarks but didnt mention a scientist for that. Is that enough???

tbh it was very vague so it’s really hard to tell what would’ve been sufficient, so I just went super overboard just in case

For the spinning ball one did anyone get 44.21 metres East 0.16deg West?

 

[Interdice]

I dont remember any mod 8 questions except for scientists and mass deficit. They really done mod 8 dirty

I didnt know any apart from Thomson and Millikan, what are the other ones that involve fields?

I got that but its wrong. The ball launchee also moves

 

[Trippzy]

@carrotsss there’s your hard math questions u wanted

 

[scaryshark09]

anyone have the paper

 

[Rattlehead15]

Yeah I accounted for that. Otherwise it would be 44 flat not 44.21 at an angle. I had to use maths adv stuff like sine rule n shit
