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 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)

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

Yo who does this now 😂😂😂 it’s 4PH1. A new crappy syllabus
