**The next situation is presented**

2 big circles (blue ones) are rotating in different directions. The left one is rotating clockwise and the right one rotates counter clockwise. Inside the 2 big circles, 2 small circles (pink ones) are embedded.

The big circles rotate at constant speed, so the small circles also rotate at constant speed.

A straight line is "connected" from the center of one small circle to another while the circles are rotating.

Having in mind that

__the straight line must has a constant length__..

The questions are:

1) What would be the separation (in millimeters) from the center of the big circle to the center of the small circle?

Note: I assume that in both cases (left and right) the distance of the centers is the same. If not, correct me.

2) What would be the difference of degrees between the small circles?
