Phase unbalance causes three-phase motors to operate at temperatures higher than nameplate ratings and, therefore, the motor cannot deliver its rated horsepower.
<h3>What is an electric vehicle (EV)?</h3>
An EV stands for an electric vehicle. Electric vehicles (EVs) are autos that are powered totally or partially by electricity.
Electric cars are extremely cost-effective to run because they have fewer moving parts to maintain and use little to no fossil fuels (petrol or diesel).
Hence, three-phase motors operating with phase imbalance run at temperatures over nameplate limits, which prevents the motor from producing its rated horsepower.

<span>Remember the definition of acceleration:
a = Δv / Δt, this is change in velocity per unit of time.
Note that a and v are in bold to mean that they are vectors.
1) a body traveling in a straight line and increasing in speed: RIGHT:
Acceleration is the change in velocity, either magnitude or direction or both. So, a body increasing in speed is accelerated.
2) a body traveling in a straight line and decreasing in speed: RIGTH
A decrease in speed is a change in velocity, so it means acceleration.
3) a body traveling in a straight line at constant speed: WRONG.
That body is not changing either direction or speed so its motion is not accelerated but uniform.
4) a body standing still : WRONG.
That body is not changind either direction or speed.
5) a body traveling at a constant speed and changing direction: RIGHT.
The change in direction means that the body is accelerated. The acceleration due to change in direction is named centripetal acceleration.

Answer:
because the car needs gas so why wouldnt it stop working
Explanation:
EXPLANATION: In Summer 2016, I took the decision to buy a car which was impulsive in nature. The car was being offered at a huge stock clearance discount by the dealer and the car was also a limited version much loved by my father. So, to get the last minute deal I bought the car within a week's notice.
ANSWER 2: The decision was taken because the car was limited and it was a huge stock clearance from the dealer's end after which the car's production was stopped and it won't be available. The car being my father's favorite, I wanted to gift it to my dad.
ANSWER 3: The consequence of the decision was I had to get loan from finance company with a tenure of 5 years. The car was well out of my budget. I made a down payment of whatever savings and I got my loan.
ANSWER 4: If the decision was to made all over again, I would prefer to calculate my finance first. I would prefer a used car to buy for me or my dad rather than running for last minute deals from the dealers. The used car will be well within my budget and would also be offering the same features as the new car would have been.
BTW THIS IS NOT MINES :(
Answer:
A. 30 m/s
D. 15 kilometers
Explanation:
Vector quantities have both magnitude and direction. Among the provided choices, B and C are scalar quantities as they have no direction.
30 m/s is the magnitude for velocity, a derivative of displacement.
15 kilometers is the metric magnitude (10³m) for displacement.
