1) Would it be correct to state the following: "The longer the radial distance (the distance from the center of the gyro disc) and the lower the height from ground to disc, the greater the angular momentum, and, thus, the more stable the gyro." It seems to me that torque must, somehow, be related to the matter, but not sure if I am on the right track by taking the radial distance as starting point.
2) Are there other differences in the properties of the gyroscope illustrations shown below?
Note: I received the questions exactly as I present them here from the organization I got them from. Therefore, I suffer from not being able to provide more context and specifications. I am only being able to provide my assumptions based on my preliminary knowledge.
Please note that I am a beginner (maybe intermediate) at physics.
