If the right frequencies are overpowered and saturated nothing/no payload goes through.
Only answer would be the usage of a broader frequency band, but then again cell phone does exactly that and is still jammable.

Radio falls off quite quickly with distance, so I would think two nodes far away from the jammer would still be able to hear each other because they are closer to each other than they are to the jammer noise.
Depends entirely on the antenna. A jammer just increases the noise floor to above operational levels. A 5db antenna will be more affected to jamming then a 23db antenna because it is listening to a more narrow space.
The distance and location sure have a huge impact, but actual jammers use so much energy energy compared to the well regulated devices. I’m not sure anything comes through.
A good example is drones or starlink jammed in Ukraine. The drones need to change frequencies regularly as the jammer saturate a set of frequency bands. Starlink on the other hand seems to be run with a frequency hopping mechanism, which is more robust by design.
Different areas of tec and use cases, but the principles are the same.
If Meshtastic were as widely used as cellphones in NYC, communication over the mesh would be completely impossible anyway.
