I spent ****ing hours yesterday going over every single circuit calculation in every paper, doing all of them in the textbook, and there's wasn't a SINGLE standard circuit calculation in the entire ****ing paper.

**** you AQA.

same, the c**ts

mebs i'll get method marks please

Nah you'll get 0 marks. Examiners will cry at the sight of your paper

I did the calculation to get 2700 ohms resistance, but then thought that a potato couldn't have such a high resistance, so put it at 2.7 ohms, how many marks would i get?

What did you guys write for the power rating and instensity question? And the power in the light bulbs?

i put that the LED would work but my explanation was vague, idk

for that question, i said lamp Y has a lower resistance than lamp X so a greater current flows through Y than X or something

It wouldn't work (I calculated it using some fun maths :biggrin:

)

it's dds
charge is -1, strangeness is -1 and baryon number is +1
sss would give a strangeness of -3 so it wouldn't be conserved

same here

Not true. It depends entirely on what structure you gave for the neutral Kaon. One would give you dds.

The other would give you a strangeness of -1 on the left and +2 on the right, meaning you'd need -3 to be balanced.
