For the mug qustions
Could you put volume of liquid
I think it had to be about the mug itself apart from the material so the answer was something like the colour

For the infrared and microwaves question I said they both travel at the speed of light in a vacuum and they are both transverse waves.
Would that get me 2 marks?

Thats what I put down. My friends said it was wrong. 25000/something= 340m/s. Are you certain?

I can't remember the details of the question to be honest with you, but I did double-check and I didn't see anything wrong with it? I can't really remember it tho

for the rural one could i have put that it would be expensive connecting to the national grid so the amount of electricity generated wouldn't be worth it?
Same I said there's a small community in the area so the costs of all the transformers and cables wouldn't be worth it..?

No. The full 1 mark will be given only if you wrote Cosmic Microwave Background Radiation.
I think they would accept that as that is pretty much the answer but you only forgot one word

Do you think I'd get the mark for saying that both waves travel at 3 x 10^8 but I didn't write in a vacuum?

What did you have for that then? I knew glass is a poor conductor, but how else can you explain energy transfer by conduction in a glass? there must be electrons free to move?
