Hey, I wrote that first test, and sorry about the bad wording in retrospect. Most of the questions were meant to be straight-forward. Typically, though, I try to make the questions have some sense that they are coming from somewhere (eg. the inclination was derived or modeled somehow working with data and theory) rather than just saying the value is blah (and in retrospect again I failed at that considering how I just gave other values in those problems, but again this wasn't meant to be the most impossible questions >.>). The other thing I phrased admittedly badly was the ratio of velocities. This one I meant (but didn't express well) to write that the ratio of velocities were determined assuming no inclination. Accounting for inclination modifies it slightly because then we are actually viewing a component of the star's radial velocity in reality, so you have to multiply it by a factor of sin(i).I'm back; this of this as part one of two, as I still have a list of National test images to ask about. This is higher priority, though. If anyone can help, my team and I would really appreciate it!
National Site NY Test #27
We've had difficulty locating the phrase "inclination derived" and are unclear how inclination, itself, relates to the rest, particularly what we're looking for.
National Site MIT Test #24(e)
There's clearly some relation we don't know about in order to find this ratio.
Just for reference when I take it, what were the top raw scores?Just uploaded the test I wrote for MI Region 8 to the test exchange.
Based on the score distribution, it was probably a little too hard for a typical Regionals, but it's still good practice
