A 1-megaton nuclear weapon produces about 4 x 10-15 J of energy How much mass must vanish when a 5-megaton nuclear weapon explodes?

If 1 megaton ==> 4 x 1015 joules, then 5 megaton ==> 2 x 1016 joules.
Using Einsteins Equation:
E = m c2.
m = E / c2.
'c' = speed of light = 3.0 X 108 m/s.
m = (2 X 1016) / (3.0 X 108)2 = (2 X 1016) / (9.0 X 1016) = 0.22 kilograms

Why shouldn't we use nuclear energy?
in case it explodes
How do create a nuclear weapon?
A nuclear bomb contains two parts. The Uranium and Hydrogen. When on first impact the hydrogen canister explodes trigering a reaction happening in the uranium which explodes at heats of over 3000 Degree Celcius.
How far will a nuclear bomb reach when it explodes?
That depends on yield and burst height/depth.
What is the name of the process in which a nuclear fuel produces heat?
Nuclear fission
A limiting factor for using nuclear energy is the what it produces?
i think it is nucler enegry A limiting factor for using nuclear enegry is the what it produces is enegry transformation.
What happens when a nuclear bomb is set off?
It explodes.

How is nuclear energy is used to create nuclear weapons?
We don't create it, We harness it, The uranium exceeds above 3000 degrees and explodes.
What type of nuclear chain reactions are atomic bombs?
What happens is the nuclear bomb explodes and something like gas comes from it and it disinigrates you
How far will a nuclear bomb reach when it explodes?
That depends on yield and burst height/depth.
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
What is nuclear accidents?
When a plant for nuclear power (breaking atoms in fission) explodes because of a malfunction within the pipes as the nuclear reaction takes place. It super-heats, explodes, and often shoots dangerous gases into the air for days, even weeks, that can cause radiation poisoning among other problems.
In a nuclear power station the process that produces heat is called?

What is the name of the process in which a nuclear fuel produces heat?
Nuclear fission
