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
It was the hardest one I think. I wrote that the gradient = 1/R. Resistance increases as voltage increases because as voltage increases current increases therefore temperature increases which means that the particles in the filament vibrate more which increases the resistance. I used data from the graph.

I messed up the radioactivity questions
Sources: I wrote radon gas and cosmic radiation. The tube is the Geiger-Müller tube. The experiment: measure radiation without source. Repeat and take average. Measure with source. Repeat and take average. Subtract bg from answer. Final answer

What did you write for the question about what happens to the density of the material... ? I can’t remember exactly

I wrote that the density of the material does not change because density is affected only by mass and volume. Then I quoted the density equation: d=m/V

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.

Question:
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)

What did you write about the wavelength of sound waves?

I wrote since the speed decreases and frequency remains constant, wavelength decreases because speed=freq*wavelength

The transformer is not much efficient now. Input current increases as resistance increases but input voltage remains same. Not sure it’s right duh

I wrote that but then I crossed it out and wrote that it remains the same because they said that secondary current and voltage remain the same
