That depends on:
The power of a nuclear bomb is a very tiny fraction of the power of the sun.
Build a missile for launching satellites into orbit. Build a nuclear bomb. Replace the satellite payload of your missile with that nuclear bomb. Adjust the missile guidance system to drop the bomb on a selected target instead of injecting it into orbit. Simple?
By thermonuclear fusion of hydrogen, producing helium. The same process that produces the energy in a hydrogen bomb (although the sun fuses far more hydrogen in the same period of time than the largest hydrogen bomb ever speculated would fuse during its entire explosion, thus producing more energy than such a bomb).
If you are referring to the blast of a nuclear bomb, you could easily lose your vision.
with a nuclear weapon they vary from short and long distances it depends what they equip the missile with like external boosters if everything is added which could make it fly further it would reach almost 7 000 miles ish give or take a few hundred
That depends on yield and burst height/depth.
Never, as far as we know.
That will depend on the size of the bomb, how far above ground it explodes, and how far away it is from you.
your question is unclear. By far do you mean range or distance of an effect? If distance of effect, which effect? By large do you mean physical size or yield? Be more specific.
depends on the size of the nuke, and how many you drop
You wouldn't be able to protect yourself, because you will instantly die if a nuclear bomb is dropped, as it is so powerful!
It can't go any where it can travel in an aeroplane.
11.3 square miles
No. A lahar carries far less power than a nuclear bomb. However, large explosive eruptions, which can lead to lahars, can be as strong as or stronger than a nuclear explosion.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.
the hydrogen bomb, is a nuclear bomb
A hydrogen bomb is, by far, the most destructive weapon that mankind has ever invented. It is the most powerful type of nuclear bomb.
