    Did anyone get 24V~ for the 4 marker (Turning Points)??
    I think so!! My mind has a habit of forgetting everything I did the minute I walk out of an exam though so I may not be the most reliable source...

    I said dwarf because the radius is smaller than the sun and the temperature is higher than the sun

    Does anyone know how they do the grades? As in, the optional modules (A-D) may vary with difficulty paper wise. Do they work out the grades for everyone who does 5A for example so the grade boundaries for that paper could be lower than 5B for example. Or is it just all in 1?

    It was a dwarf star - it was 16000 Kelvin ( B Type Star ) and it was almost 100 times smaller radius than the sun

    Dwarf- about 10* lower radius than our sun but much hotter: the main sequence snakes to the right but this star would have been at the bottom left.

    Apart from the 6 marker on nuclear and thermal. I thought that was good. I had literally 0 idea how to answer that 6 marker!

    The temperature was 5000k not 16000, the value you used was the peak intensity, not the peak wavelength, the peak wavelength was the value as far right as possible

    The peak wavelength is where the peak intensity occurs...

    M8, the peak wavelength of a star is the wavelength in which you get the peak intensity OF THAT WAVELENGTH

    I did medical. I hate lens equations so I know my answers is most likely wrong, but I got 0.19m. How about you?
