this was about useful energy out not efficiency


Oh yeah true I forgot, at least I didn't multiply by 100 lol
High grade boundaries i think
I wrote vibrations for question 2 :frown:

Did anyone else put 22 degrees, think i messed it up


same!! i think you had to minus it from 100
anyone do foundation ?

Anyone remember what the question was for the one after the 78 degrees one. It was something to do with power output. My friends said something about multiplying by 60. And I didn't do that!!!

The answer was something to do with watts if that helps!


I think it was average P = E/t = 46,200kWh/2h = 23,100W

What did people put for the similarities between infrared and micro waves?


I put they can travel in a vacuum and they transfer energy - don't know if I'm right though

Yh you had to multiply the 2 hrs by 3600 and get the time in seconds and the final answer would be in watts. I got 6.42 watts

I added it to the 100 to get 122

I think you had to subtract it as it was a temp decrease to get 78

Noooooo 7200 seconds for 2 hours
Will i get the mark for one of the first if i put the wavelenght was similar to the insect rather than the same as?
I made he same mistake but think you can still get two marks for the working out of tempretre difference and applying the data in the specific heat capacity equation

I don't think so because similar could suggest greater or larger, don't worry I said greater haha

for why france use nuclear could you say that it's cheaper and the others are unreliable, (that nuclear can be made whenever needed?)

They both travel at the speed of light
They both can travel through a vacuum
I put echo location for the echo question😭😭 do you think I'll get the mark?
