The Cosmic Ray is a natural way for nuclear fission and nucleosynthesis to occur. It refers to the formation of chemical elements from the impact of cosmic rays on an object.
Answer:
Number of turns per unit length will be 
Explanation:
We have given that strength of the magnetic field produced by the solenoid B = 7 T
Current in the solenoid i = 200 A
Let the number of turns per unit length is n
Magnetic field due to solenoid is given as 
here 
is permeability of free space n is number of turns per unit length and i is current
So 
Subatomic particles
Explanation:
Grand unification theory or GUT is a model that tries to describe the universe.
