When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel
before interacting.
Let t is the time interval required for the strong interaction to occur. It will move with the speed of light. So,

So, the time interval is 
B. kinetic energy increases and potential energy decreases
Answer:
chemical potential of a species is energy that can be absorbed or released due to a change of the particle number of the given species, e.g. in a chemical reaction or phase transition.
