    Yeah the question specifically said "subject to the conditions stated above", which implies there's only one velocity - the one given, so I think they'll reject the "different velocities" answer.
    That is good because I didn't write that

    Are you sure that it was the velocity and not the speed that was constant?

    I've done a question like that before. You'll only lose one mark if the wave was drawn correctly.

    At the top it said "water passed through the turbine at a speed of 12ms^-1". Velocities shouldn't really come into it (water currents flow in one direction - there won't be any going to opposite way to counteract it)

    70-76 for an A I think, recently, it has been about 60 before but that won't happen again. I predict 90/100 is 100% UMS

    24kW

    120 km / (80 km h^-1) = 1.5 hours.

    1.5 * 16 = 24

    This is providing I can remember the numbers correctly.

    What was the answer for the 1 marker about the maximum wavelength that can create 3 fringes. Something like 630nm?

    Yep. You assume order 3 is at 90 degrees, as this is the maximum size of order 3 hence maximum wavelength.

    Isn't that just the capacity of the battery though in kWh?

    I can't remember, why what did you multiply 1.5 by?

    I don't know to be honest, I can't remember either but I put 24 down and also something like 10.6kw, don't know why haha

    That question has gone completely blank in my mind after the 1.5 mark, I can't even remember what the question said. I think you're right though, I may have lost 2 marks.
