    Physics Question: On Velocity-Wavelength- Frequency

    Might not be in the air medium Your answer seems correct OP. But it doesn't really make sense that the frequency is that low. Frequency of light is typically in the x10^15 area.

    Just get the highest (lowest) rank you can possibly get. If you're cohort isn't that strong, then obviously you need a higher rank. If the cohort is strong, you can remain with a decent rank.

    Why is g = +9.8 in the g-force and acceleration formula when gravity acts downwards?

    Re: Why is g = +9.8 in the g-force and acceleration formula when gravity acts downwar So the formula is thrust-mg / m (apparent weight/true weight), taking g as -ve would work here. I think your version of the formula takes into account the negative and makes it positive for you.

    ATAR Estimation.

    I'd say anywhere between 80-93. I think it's very probable that you will get an atar of 60-75, most likely higher though

    Little to no study. Freaking out?

    Of course you can. You're ranked first. Just start cramming for it after english paper 2, going through at least 2 past papers (try without notes and use notes when checking answers) How big is the cohort and what is your school rank?
