Answer to Question 1

It's believed that all radio galaxies have lobes. If the lobe happens to be pointing at us, it appears minimized and we see mostly the core.

Answer to Question 2

1. In the absence of a net force, an object moves with constant velocity.
2. Force = rate of change in momentum or mass times acceleration.
3. For every force there is an equal and opposite reaction force.
