Do you think I would get marks if I said that the two variables that impact luminosity are mass and surface area instead of mentioning temperature?

same lmao

dunno if this has been put in the thread yet but what’s everyone thinking alignment might look like?

from what I’ve been hearing and how I found it, around 85 for band 6 cutoff

is that just bc it was an easy test or does phys always scale like this?

Easy test. Physics usually scales high 70s-low 80s. Last year was a massive outlier and this one probably will be to a lesser extent so maybe theyre tryna make physics an easier subject now idk

in 2019-21 it was decent alignment/scaling but 2022 aligned awfully and scaled worse asw, and I think the consensus is this year was slightly harder than that

slightly harder but still rlly easy? everyone im talking to is so confident abt the test its crazy

yeah still definitely easy compared to 19/20/21

 

[carrotsss]

what about chem

chem was slightly easier than usual asw, maybe 86 or so

 

[natsnapshoot]

what about chem

Similar to last year, which was 85

 

[carrotsss]

coutning chem was like 40 marks of calcs this year if u include q that required calcs to be done like the 7 marker grapph
many people found it harder but overall ive seen conquer and it makes sense cus the top students like us should find it easy
but i reckon it shoud have decent alignment
i dont know why alignment was so bad last year as well it should be more generous

scaling in chem last year was quite generous though which makes up for it

Well yeah, the average Chem student probably would have found it harder than last year so it should be ok

ik wrong chat but would 75 English adv align to and 65 ext 2 align

 

[scaryshark09]

ik wrong chat but would 75 English adv align to and 65 ext 2 align

75 english would be around 83
65 ext 2 would be around 89

Does anyone have physics solutions

Most of them are done by eddie:

1-20: DCCBDDCBADABCCACBABD

 

[tywebb]

There may be a delay for 33,34 so if you don't like delays, maybe someone else here can do 33, 34 and that will finish the paper.

For question 24, Would you have to say the direction of the B-field?

 

[Interdice]

For question 30a, he's talking a lot about force as EMF. EMF is voltage not force???

 

[tywebb]

Here is a solution to 33 but it is not eddie's

The statement that the interaction of subatomic particles with fields, as well as with other types of particles and matter, has increased our understanding of processes that occur in the physical world and of the properties of the subatomic particles themselves is supported by a vast body of experimental evidence and observations. Here are some key points that justify this statement:

• Quantum Field Theory: One of the most successful theories in modern physics is quantum field theory. It describes how subatomic particles interact with fields, such as the electromagnetic field (described by quantum electrodynamics) and the strong nuclear force field (described by quantum chromodynamics). These theories have been tested and validated through numerous experiments, and they provide a profound understanding of how particles interact with these fields.
• Discovery of Subatomic Particles: Through experiments with particle accelerators, scientists have discovered numerous subatomic particles, such as electrons, protons, neutrons, quarks, and more. These discoveries have greatly expanded our knowledge of the fundamental building blocks of matter and their properties.
• Fundamental Forces: The interaction of subatomic particles with fields is responsible for the fundamental forces in the universe, such as electromagnetism, gravity, and the strong and weak nuclear forces. The study of these interactions has led to a deeper understanding of the nature of these forces and how they govern the behavior of matter on both cosmic and microscopic scales.
• Unification of Forces: The study of subatomic particles and their interactions has led to the development of grand unified theories and the quest for a theory of everything. These theories aim to unify the fundamental forces and have made significant progress in bringing together the forces of the Standard Model (electromagnetic, weak, and strong) into a single, coherent framework.
• Cosmic Observations: The interaction of subatomic particles with fields and with cosmic matter has also increased our understanding of the universe's evolution. Observations of cosmic microwave background radiation, for instance, have provided insights into the early universe and its properties, and these observations are closely tied to particle physics principles.
• Particle Colliders: Experiments at particle colliders, such as the Large Hadron Collider (LHC), have allowed scientists to recreate extreme conditions that existed shortly after the Big Bang. These experiments have provided crucial insights into the properties of subatomic particles, the Higgs boson's discovery, and the validation of the Standard Model.
• Applications in Technology: Our understanding of subatomic particles and their interactions has also led to the development of many technologies, including nuclear power, particle beam therapy for cancer treatment, and particle detectors used in various fields, from medical imaging to materials science.

In summary, the interaction of subatomic particles with fields, other particles, and matter has been a cornerstone of modern physics, leading to the development of fundamental theories and significantly advancing our understanding of the physical world and the properties of subatomic particles. This understanding has not only deepened our knowledge of the fundamental forces of the universe but also had practical applications in a wide range of scientific and technological fields.
