Rubber is an insulator that doesn't allow electricity to flow freely through it.
Answer:
Temperature
Explanation:
Temperature is the key factor in dividing the atmosphere into various layers.
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
