When they are lifted up, would the gravity pull take their oxygen, thus leaving them motionless and breathless? What exactly would happen? And if not dead in the tornado, would it be likely to die falling to the ground (with the gravity pushing against you)? Please also explain how tall and wide the average tornado is! It would also be very interesting to hear from someone who has really been in one! Thanks :)

My stats is a little rusty. I need to know the difference between piared and unpaired data. For my experiment, I'm comparing the size of plants under two different growing conditions. So there is two columns of data, each representing the weight of each plant under two kinds of conditions.

If 2 circles have equations:

Circle A => x^2 + y^2 -10x -12y +36

Circle B => x^2 + y^2 + 8x +12y -48

Find the point of contact that both of these circles meet at.

N.B. There is a question identical to this in my math textbook. I know the answer is (2,2), I just need to know how to find it i.e. a solution.

If it helps speeds things up.
the centres and radii are (5,6);5 and (-4,-6);10 respectively
