Erm you didn't have v - the velocity - you had the potential through which they are accelerated

But I used eV = 1/2 mv^2 to get v then subbed into v/Br

127.24 i got o.O
Yeah think I got this. There will be leeway for rounding though surely
3. Did anyone get 1700 for the specific heat capacity ?
4. Did anyone get 0.27 for the density question in the nuclear paper?
5. How'd everyone find it? I found it to be a more difficult than average paper but doable

Yes
9. What did people say for the quantities that change or whatever it was for electromagnetic waves?

I said the direction of the magnetic/electric fields.
Both methods will get the marks chill

lol not if the answer is wrong who I was replying to got x10^8 so definitely not right

I think using the values they gave us it rounded to 127 but using the figure 3, it was 128?

Magnetic field; electric field; in phase

14. there was a 1 mark, energy given to the ice, was it the same as the number in the question?
Got 1.2

Posted from TSR Mobile
Same 👍

No, it was that energy minus the latent energy of fusion.

i think i got them the other way round? wasnt specific heat capacity 2120? and the energy was 2490?
I'm certain I got these

I know which one you mean but can't remember what I put 😕 I'm fairly sure I did a calculation thougb
