# Tuesday 19th AQA Physics Unit 1 POST EXAM OPINIONS Watch

1. Seemed much harder than previous past papers to me...
2. It was pretty hard
3. ****.
4. What did everyone get for the quark composition of X?
5. That was ****ing sh1te. Potato? The wording on some of the questions... de broglie wavelength from Question 4b. NO. WE DON'T HAVE THE WAVELENGTH FROM 4B, WE USE THE DATA FROM 4B TO FIGURE IT OUT. If I could swear on these posts this would make it 18+ only....

What did everyone get for the quark composition of X?
I got dds
7. **** AQA, **** that test, **** electricy. Pretty hard is a soft way to put it.
8. yh sdd for quark combo for me
9. What did you all get for the speed of the electron and the resistance of the potato?
10. really hard, I actually wanted to cry
11. the speed of electron Q confused me so I didn't get an answer

think I got 2700 ohms for internal resistance of potato

i got that for the internal resistance too
13. How can the quark composition be SDD when there was a strangeness of -1 on the LHS (k-) and a strangeness of +2 on the RHS (k0,K+) the question stated strangeness was conserved so X=SSS

How can the quark composition be SDD when there was a strangeness of +2 on the LHS (k0,k+) and a strangeness of -1 on the RHS (k-), the question stated strangeness was conserved so surely it would be SSS?
There was a proton and a K- on the LHS, strangeness -1?
15. Potato question's ruined me
16. There was a strangeness of -1 on the LHS, and a strangeness of +2 on the RHS strangeness MUST be conserved X must have a strangeness of -3, so X must have been SSS
17. Couldn't answer the bit after 4b and planned to go back but didn't have time, or the last question, or remember the quark coposistion of a K0, lets hope for low grade boundaries and perhaps some kind ecf or im screwed

For the speed I got 6.1x10^-19 ? and the resistance i got 2750

completely agree that was bull****

Already a thread for it, I wouldn't bother reading it though, the general view is that it was considerably harder than previous years, ergo lower grade boundaries.
