Many things. I'd need more details on exactly what effects you are interested in to say.
You get a rather large explosion.
Nuking the sun is not possible with current technology. However, theoretically, if it were possible, the sun is so massive that a nuclear explosion would have negligible impact on it. The sun's nuclear fusion reactions are much more powerful than any man-made nuclear explosion.
No, a nuclear explosion on a nuclear power plant would not cause the explosion radius to increase. The explosion radius would be determined by the yield of the nuclear weapon itself, not by the presence of the power plant.
No. Chernobyl is in Russia.
because the bomb was designed to make it so.
There is no record of a nuclear explosion occurring on November 6, 2010. If there had been a nuclear explosion, it would likely have been a significant event that would be widely documented.
can't say exactly, but it would depend mostly on the yield and location of the explosion.
nuclear explosion?
When and what explosion? One of the nuclear test shots. If so which?Remember Chernobyl was not a nuclear explosion, it was a steam explosion and graphite fire.
No cockroaches are one of the few organisms able to survive nuclear explosions. Scorpions cannot.
Yes, the conventional explosives would trigger an explosion of the conventional explosives inside the nuclear bomb which would blow apart the nuclear components of the nuclear bomb, causing significant alpha emitter radiological contamination but no nuclear yield.
no
