I know you have read it during revision but firstly when u think about it, diffraction increases when the wavelength is longer in comparison to the gap. I have checked with numerous people and all the physics teachers at my school agreed with me , trust me I'm 110% sure I'm right !!
I agree with rihana.c... I am pretty sure diffraction is greatest when the gap is the same size as the wavelength. If you check bbc bitesize, it says "When a wave passes through a gap the diffraction effect is greatest when the width of the gap is about the same size as the wavelength of the wave."

You forgot to subtract that from 100, so 100 - 22 = 78*C
i almost wrote 22 THANK GOD I DIDN'T

For the 2 factors that effect the energy transfer of the mug, I put the surface area of the mug and the material the mug is sitting on. Is that correct? (Near the end of the paper)

For the disadvantages of nuclear power stations, would I get the mark if I said "They carry risks of a major catastrophe, since nuclear fuels are involved"?

For 7, would dark matter/energy be acceptable?

Was the six marker not about the hydroelectric dams but turbines in water?! I talked about damage to habitats and possible flooding as disadvantage.Are hydroelectric generators the same thing (I know the hill thing has a turbine but I don't know if that's what they were asking)

about generating electricity not habitat destruction

Yeah I meant about the actual method itself; were they going to put turbines in the rivers or use the dams?
I thought I had that six marker...

would it be acceptable on the mug question about energy transfer to say that the surface area of the mug, the liquid exposed affects the rate?

I was careful about that because it might not count but I suppose you will get the mark

That would be a solid A maybe even A*
