These questions are for those not sure of the answers.
Given two nearly identical DC motors with permanent magnet fields that are wired in parallel.
If one motor shaft is rotated, then what does the other motor do?
Given an air cylinder closed at both ends. The port on one end is connected to a pressure gage. The port on the other end is open to atmosphere. Move the piston to the open port end, and allow the pressure gage to equalize.
Quickly force the piston to the closed port end, and hold the position.
How does the pressure gage reading vary with time, and why?
