The noble gases have eight valence electrons and as a result are stable.
If an atom consists of 8 valence electrons, they have a full octet, and do not need to bond, which makes them "happy".
The equation for kinetic energy is KE=1/2mv^2
So if the small vehicle AND the large vehicle both had the same speed, the large vehicle would have more kinetic energy since it has greater mass, resulting in a much more larger stopping distance than the smaller car.
Answer:

Explanation:
A 3-wire, 120/ 240 V circuit from a three-phase delta transformer contains two ungrounded conductors and one grounded conductor. The grounded conductor carries the unbalanced current when the circuit is not balanced.
A neutral conductor has the same equal potential between it and all ungrounded conductors of a 3-wire system.
The current on the neutral conductor is
percent of the ungrounded conductor current.
