Answer:
28.9 seconds
Explanation:
Convert km/hr to m/s.
83.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 23.2 m/s
16.4 km/hr × (1000 m/km) × (1 hr / 3600 s) = 4.56 m/s
Given:
Δx = 400 m
v₀ = 23.2 m/s
v = 4.56 m/s
Find: t
Δx = ½ (v + v₀) t
400 m = ½ (4.56 m/s + 23.2 m/s) t
t = 28.9 s

Explanation:
Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily equalize themselves, causing the instantaneous release of as much as one gigajoule of energy. ... Humans have deified lightning for millennia.
Lightning happens when the negative charges (electrons) in the bottom of the cloud are attracted to the positive charges (protons) in the ground.
