The difference between conductors and insulators is because
of electronic structure of atoms and molecules.
Anywhere we have free electrons, we have a hard conductor
where free electrons help in conduction.
In electrolytes, charged Ions do conduction.
Dielectrics (or insulators) don't have free electrons current.
Free electrons mean, the electrons that are not related with
a specific atom, they are allowed to move nearby the crystal lattice.
Well, im pretty sure that when we do touch eachother, the atoms themselves are touching. idk if this is what ur looking for but hope this helps.
Answer:
The time taken for the ball to get to the batter is 0.41 s.
Explanation:
Given;
initial velocity of the baseball, u = 45 m/s
horizontal distance between the pitcher and the batter, X = 18.39 m
The horizontal distance or range of a projectile is given as;
X = ut
where;
t is the time of flight
u is the initial velocity
t = X / u
t = 18.39 / 45
t = 0.41 s
Therefore, the time taken for the ball to get to the batter is 0.41 s.
