Answer:
An electric current is said to exist when there is a net flow of electric charge through a region.
Explanation:
In electric circuits this charge is often carried by electrons moving through a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionized gas (plasma

"Sound" is all vibrations in the medium. Whether it happens to be water,
air, steel, whatever is vibrating, the sound is the result of the vibrations.
When the vibrating stops, the sound stops.
Answer:
16.2 s
Explanation:
Given:
Δx = 525 m
v₀ = 0 m/s
a = 4.00 m/s²
Find: t
Δx = v₀ t + ½ at²
525 m = (0 m/s) t + ½ (4.00 m/s²) t²
t = 16.2 s
