Answer:
Time, 
Explanation:
Given that,
When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel  before interacting.
 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 
 
        
             
        
        
        
Answer:
      v₂ = 70 m / s
Explanation:
For this exercise let's use Bernoulli's equation
where subscript 1 is for the top of the mountain and subscript 2 is for Tuesday's level
  
           P₁ + ½ ρ v₁² + ρ g y₁ = P₂ +1/2 ρ v₂² + ρ g y₂
indicate that the pressure in the two points is the same, y₁ = 250 m, y₂ = 0 m, the water in the upper part, because it is a reservoir, is very large for which the velocity is very small, we will approximate it to 0 (v₁ = 0), we substitute
          ρ g y₁ = ½ ρ v₂²
          v₂ =  
let's calculate
          v₂ = √( 2 9.8 250)
          v₂ = 70 m / s
 
        
             
        
        
        
The correct answer is compound
