1 or 2 depends on the total marks of the question (I forgot how many marks it was)

6 markers was 1620 and 2.6

no?? Everyone i spoke to got 5.2?

What did y'all write for fusion for 3marks??also the othe rone was nuclear explosion right and what ab for the specific heat capacity?

yeah i cant remember if it was 2 or 3 marks but i got 4 half lives but didnt times it by the no of days per helf life

It was 2.6, you must've forgotten to multiply by 0.5 lmao

Nuclear fusion releases energy through the conversion of a small amount of mass into a large amount of energy. In fusion, two light nuclei merge to form a single heavier nucleus. The process releases energy because the total mass of the resulting single nucleus is less than the mass of the two original nuclei. The leftover mass becomes energy.

What did people put for power output with the 2 switches, i said the power decreases because the current is shared between the two paths so current decreases but idk

the answer was in the first line of the question about how some cars release co2 when generating electricity so u had to say more co2 bcs more electricity needed in order to travel a greater distance

WAIT for the power output
Closing both switches increased power output
Because current increased
Because resistance decreases as 2 resistors decreases the total resistance as current flows via path of least resistance
So p=Iv and pd constant I increases so p oncrease?
