I definitely have made so much silly mistakes, You are working with too many numbers and a single decimal could lose you marks.


I know right :frown: so scared lol

Btw i tried doing star jumps before the exam and it actually worked, for some reason it got me in the zone and i didnt feel so faint lol

Yeah thanks 1.9 sounds familiar it was times ten to the power of something I think

Yeah :smile:

Did u get 0.75Kbq for the half life 1?
Would you get the mark if you said the Geiger Muller tube detected infrared

Yeah it was 1.9x10 something something i got the same too


YASSS :biggrin: and the Wr was 1 so the answer for A and B were the same but just different units ?

What did you put for the metal and the house, It was like question 1 c and it was about how the metal protects the house from storms ?

For the electronic switch was it 0.7 V or no ?

HERE YOU GO. Oops caps.


Is 11 really B? I think the ray should bend towards the normal (A) not away from it?

Yes :smile:


Would you still get it correct if you converted it from KBq to just Bq ?
What did everyone get for the question that asked for an energy change? I got light energy to electrical energy. I didn't like that one.
Also that question about choosing the part of the spectrum or something? I got microwaves but idk.

Yes you should.

What did everyone write down for the open ended questions?

Hahahah Yeesss Glad it helped :smile:

How did you find the half life question ? It was quite similar to the example I gave you yesterday.

Yeah I put microwaves for that also

I also put Light to Electrical

I was contemplating whether it was light or heat for solar panels but I put light :smile:

Hope its correct !

Same. :P
For the first question in Paper 2 I got 2x104 A I think. So 20000A
Can someone give the right answers for multiple choice please

OMG I GOT THE SAME!!! Major thanks to @Ethan100 for teaching me half life last minute :rofl:
