The definition for length of segment is the distance between the endpoints of s segment
If you travel along the length of the segment from one end to the other, whether it is curved or straight, you can measure its length. The midpoint is the spot on the segment at this mid length, equidistant from the endpoints when moving on the segment.
Mostly because, assuming it just one segment, a midpoint by definition (mid- means middle) is the point at the exact middle of a line segment; whereas the length of the segment is the entire length of the segment. Pretty much, a midpoint is a point in the middle of the line, the length is the measurement of the same line.

It is true. The book says "The maximum distance a signal can travel and still be interpreted accurately is equal to a segment's maximum length. Beyond this length, data loss is apt to occur."
For a single link the maximum is 100 meters.
40 km
For any Cat 5 cable, the maximum segment length is 100 meters per segment.
The signal can only be sent so far before becoming distorted
For use in networks the maximum segment length would be 500 meters
1000 base‑lx
Most UTP cable is limited to 100 meters.
Category 6

10BaseT is another name for co-axial cable. It has a maximum cable length of 185 meters or 607 ft.
