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 🫡

 

[Alamjot]

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🥲

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

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

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

Well 44m was from the launcher, but it asked from distance from new launch point, so you have to find distance between new launch point which is vertical 4m above original launch and 44 diagonal from original launch, i would draw it but im not at my laptop
