comment What are the differences between NiMH and Alkaline batteries for the EV3?
The difference between alkaline and NiMH is not so clear: Good NiMH have a discharge curve flatter than alkaline so they may actually last longer (even if initial performance is lower than alkaline). See philohome.com/batteries/bat.htm.

comment What is the purpose of this plate with door rail?
And the 2 stud version was often used to secure the old 9V motor (bricklink.com/PL/71427c01.gif?0) that had two grooves on each sides, allowing it to be removed easily.

The duty cycle percentage is the ratio between powered time over cycle period. Eg. here, a 30% duty cycle at 1200 Hz means 250µs on / 583µs off.
