Answer:
30643 J
Explanation:
= Vacuum permeability = 
t = Time taken = 1 ns
c = Speed of light = 
= Maximum electric field strength = 
A = Area = 
Magnitude of magnetic field is given by
Intensity is given by
Power, intensity and time have the relation
The energy it delivers is 30643 J
The
sun is a ball of hot gases containing different kinds of elements at different
cores. It has a very high temperature that radiates all throughout the Milky
Way galaxy. The sun has three main parts; photosphere, chromospheres
and corona. The outer core of a star located at the chromospheres contains
mostly of hydrogen. Inside the hydrogen is helium then carbon, oxygen, neon,
magnesium silicon and the inert gas. The photosphere is scattered by the loose electrons in the corona’s plasma.
