1. How did everybody find the exam
2. pretty easy, you?
3. so so
4. What did everyone put for the last question about the induction cooker?
5. I loved that paper so much!
That 6 marker was one of the best things I could have dreamed for!

I put cheaper, because gas is expensive and no risk/smaller risk of fire.

Yiu?

I put less chance of electrocution and then it was cheaper cause there was no need for electricity
7. What are the answers to:

The metal pan above the ac wire?
The increase in current?
After 45 minutes, the KW the light bulb thingy?

I think the KW one was 130.
45/60 = 0.75 and you had to find it on the graph.
The rest I made up absolute BS for.
10. sorry I meant the how the induction worked with the AC wire
11. worst exam ever
12. All I knew to say was delocalised electrons in the metal pan can carry charge 1/4 marks I guess

wish i could help out but i mega messed these and the other questions up
14. easier than i thought but i know i really messed up
15. The pan was about induction;
-The ac wire creates an alternating magnetic field
-Magnetic field is moving (because it is alternating) so is cut by the pan
-Induces a voltage
-Because it is a complete circuit, induces a current,

The metal pan, it was like a transformer so the alternating magnetic field was cut by the pan and so a p.d was induced and therefore a current was induced.
Increase in current, i put closer to wires, more wires and a bigger pan?
Radio waves, have longer wavelength than microwaves so the universe would be getting smaller if the explosion was radio waves
I think i got 142KW

I FOUND IT HARD!!!

I got 142 and the expanding thing, but the pan one threw me off so much forgot what to put... 😩
