The graph shows the kinetic energy of both a school bus and a pickup truck as they move at various speeds. Under which of the following conditions can the pickup truck have more kinetic energy than the school bus?
The pickup truck is moving at 1 m/s and the school bus is moving at 2 m/s. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.
The pickup truck is moving at 2 m/s and the school bus is moving at 3 m/s.
The pickup truck is moving at 4 m/s and the school bus is moving at 3 m/s.
Answers
The correct answer is B. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.
Explanation:
The kinetic energy is related to how fast a body moves (speed), as well as, the amount of matter in the object (mass). Due to this, even if the bus and the truck move at the same speed they do not have the same kinetic energy. Indeed, the graph shows in general the kinetic energy is higher for the school bus.
However, this does not occur if the truck moves at 4 m/s and the bus moves at 2m/s because, at this speed, the kinetic energy of the truck is 30 kilojoules, while the kinetic energy of the bus is around 15 kilojoules, which is lower. According to this, the correct answer is B.

The missing options are;
A) His circadian rhythm has been disrupted.
(B) His stages of sleep are out of order.
(C) His delta waves have lost significant
amplitude.
(D) He has narcolepsy.
(E) He is experiencing REM rebound.
Option A is the correct option.
Option A; This is the likely explanation for him still feeling lethargic because circadian rythm is the internal clock of the human body that regulates the sleep-wake cycle. And when it is faulty, it results in a sleep disorder.Option B; This is not correct because stages of sleep has nothing to do with feeling lethargic after sleeping for several hours.Option C; This can't be the cause because delta waves are produced in deep sleep and they help in relaxation of the brain when sleeping. Thus they have nothing to do with feeling lethargic.Option D; Narcolepsy is a diseased condition where people fall asleep at wrong times. Again this doesn't have any effect on feeling lethargic after sleeping for several hours.Option E; REM Rebound is when one receives more sleep than they usually get. This has no impact on feeling lethargic.Read more at; https://brainly.com/question/10361445
