My recent ancestors are Jews from Russia, Ukraine, Belarus and Latvia. I uploaded my G25 coordinates to Vahaduo and Genoplot.

Image 1: The source is Modern Scaled Averages without Jewish populations.
Image 2: Same thing but reduced to 4 populations.

I am not a DNA expert. I was curious to know where my ancient ancestors were actually from. I know that South-European DNA tends to overlap with Middle Eastern, so I don't know how accurate the results actually are, or how credible the tools/websites that I used. Regardless, I thought I should share my results.

I have an Exam in Mechanics of Materials in six days. I know the material, but I have a tiny black-out regarding how to define the axes, and what is considered a positive moment.

I wasn't able to find a definitive answer on Youtube, and ChatGPT, Gemini, And Claude are contradicting one another lol.

I have several questions:
1)What is considered a positive external moment, and what is considered a positive internal moment? is the sign dependent on the direction of the axes?

2)Is there a difference between 2D and 3D in regards to positive and negative external/internal moments.

3)In my course, we usually define x along the beam, y downwards, and z to the right of the cross section. Is there a reason for that?

As I said, I know the material, this is just a tiny black-out.
Thanks in advance :)

Does Illustrative DNA give you G25 coordinates?

Are the coordinates in the "Download Coordinates" tab G25? or specific coordinates tailored for the models that are being used by Illustrative DNA?
Because according to Illustrative I am the closest to Ashkenazi Jews... but when I uploaded these coordinates to G25 calculators online, they think I'm Kenyan??

Can someone explain to me how to connect an equivalent resistor to the rest of the circle? For example, in this problem, the two middle-top 8-ohm resistors are in parallel, but how do I connect their equivalent resistance to the rest of the circle?

Is there a rule on how to connect equivalent resistor to a circle? (I am not asking to solve the problem for me)
