Technician A is Correct.
You can see this when he says that conductors have more free electrons than insulators. This statement is True.
While Technician B says that, insulators have the lower resistance than conductors. This statement is False.
Answer:
i wanna say tranverse if not surface
Explanation:
Answer:
v = √k/m x
Explanation:
We can solve this exercise using the energy conservation relationships
starting point. Fully compressed spring
Em₀ = 
= ½ k x²
final point. Cart after leaving the spring
= K = ½ m v²
Em₀ = Em_{f}
½ k x² = ½ m v²
v = √k/m x
