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

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

 

[Trippzy]

Wtf was that 7 marker

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

that's the correct answer I think because most people got that, I messed it up tho

I forgot the horizontal 🫡

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

literally everyone

 

[abelsj01]

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???

i did the same w diagrams and derivations n touched on the other scientists as well

fields/particles/matter applies to virtually every experiment/observation

LFG maybe that will make up for me not knowing how to do the 9 marker gravity thing and the stupid ring solenoid questions. Probably lost a good 15 marks between those two questions alone. Does anyone have an idea of how they think it will align? Maybe like 87 is a B6 imo?

a lotta ppl on facebook got that

How though? Davisson and Germer used no fields, Geiger marsden used no fields

imo marginally better than last year

 

[Rattlehead15]

imo marginally better than last year

Yea last year was like 89 so maybe this year like 87

I felt this one was way easier though. 2022 had a few questiosn that stumped me. This one not so much, except for 7 marker.

You think they are trying to market Chemistry as Physics Extension, because of scaling?

I thought that vertically upwards does not take into account horizontal velocity , and calculated as q vertical rectilinear question. What is max mark you can get for 7 marker projectile question then.

my first line of working was literally ux = 0🥲

Fuck me i did it right i had launcher 4m from launch and ball 44 from launch i did 44 squared minus 4 squared but i forgot to square root them, f me

 

[Engineer_192931]

Fuck me i did it right by had launcher 4m from launch and ball 44 from launch i did 44 squared minus 4 squared but i forgot to square root them, f me

I did 44 + 4 so 48 I should've known to square them

Can’t we just say opposite it by 4m since asked for relative position

 

[Rattlehead15]

Fuck me i did it right i had launcher 4m from launch and ball 44 from launch i did 44 squared minus 4 squared but i forgot to square root them, f me

Is the launcher 4 m from the initial position though? I got like 183 deg rotated, not 180 deg rotated.
(So it had rotated up to the top plus a little)

I just think 2022 theory questions were free cos the questions were so easy to understand and required simple answers, but this one a lot of easy calculations I guess
