You have a parallel circuit since it allows the electrons to travel in 2 paths, allowing the other light to stay lit.
Answer:
The distance traveled by Tina before passing David is 900 m
Given:
Initial speed of David,
Acceleration of Tina,
Solution:
Now, as per the question, we use 2nd eqn of motion for the position of David after time t:
where
s = distance covered by David after time 't'
a = acceleration of David = 0
Thus
Now, Tina's position, s' after time 't':
where
, initially at rest
(1)
At the instant, when Tina passes David, their distances are same, thus:
s = s'
t = 30 s
Now,
The distance covered by Tina before she passes David can be calculated by substituting the value t = 30 s in eqn (1):
= 900 m
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.

Sometimes called energy transformation, energy of fossil fuels, solar radiation, or nuclear fuels can be converted into other energy forms such as electrical, propulsive, or heating that are more useful to us. For example, a light bulb converts electrical energy into heat and light energy.
