I found it quite well. I would say the hardest question was the last page There was nothing about moments and only one question about density. There probably will be a lot about moments and also the pressure density equation in paper 2.
What did you write in the resistance question
I messed up the radioactivity questions
What did you write for the question about what happens to the density of the material... ? I can’t remember exactly
Just finished paper 2. It was very easy. The only hard question was the one about the transformer heating up.
They said that the transformer was 100% efficient.
The student notices that the transformer heats up a little. Explain what happens to the input voltage. Secondary current and voltage remain the same. (2)
