    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

    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

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