Answer:
Her displacement is 0 miles and her distance is 5 miles.
Explanation:
Given information:
Sophie runs in an oval track. The length of track is 5 m.
Distance is the total length of path covered during motion while displacement is the shortest distance between initial and final position.
In this case, Sophie completes one cycle in the oval track and the track length is 5 m. So, the distance covered by her will be 5 m.
Now, after completing the track, the initial and final position of Sophie will be same and hence, the displacement she covered will be 0 miles.
Therefore, option "Her displacement is 0 mile and her distance is 5 miles" is correct.

The displacement of Sophie is 0 and her distance is 5 m
The displacement of Sophie is the change in her position.
If she runs in an oval track, she will return to her initial starting position. The initial position and the final position will be equal, the change in her displacement will be zero.
[tex]\Delta x = x_f- x_i\\\\\Delta x = 5 - 5 = 0[/tex]
The distance traveled by Sophie is the sum of the total distance covered.
distance = 5 m
Thus, the displacement of Sophie is 0 and her distance is 5 m

When dropped from rest, any object will fall a total distance of 19.6 m in the first 2 seconds of its fall. How far
does the object fall just during the 2nd second (i.e., from time t= 1 s to t = 2 s)?
Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per
second. Answer B is wrong because velocity increases. Answer C is wrong because the
distance increases every second. Ans. E is wrong because the derivative of distance with
respect to time gives the velocity, not the acceleration.
Explanation:
a plane is traveling at 250 m/s north after being in the air for 1 hour, what is the displacement?
Answer:
900,000 meters of displacement.
Explanation:
250x60x60 because it is meters per second and needs to be converted to a full hour.

What is the difference between a hypothesis and a theory?
Answer:
a hypothesis is an assumption made before any research has been completed for the sake of testing (basically what you think is going to happen). A theory is an explanation for what has been shown many times. (what happened with evidence)
Explanation:
A car starts from rest and accelerates at 5 m/s/s.
a) what is the position of the car after 4 seconds?
b) what is the speed of the car after 4 seconds?

to the finish line in 5 seconds? *
Answer:
80m/s
Explanation:
The formula for velocity is [ v = s/t ] where s = displacement and t = time.

What is a description for this lionfish?
the lionfish, a longstanding showstopper in home aquariums, is a flourishing invasive species in U.S. Southeast and Caribbean coastal waters. This invasive species has the potential to harm reef ecosystems because it is a top predator that competes for food and space with overfished native stocks such as snapper and grouper. Scientists fear that lionfish will also kill off helpful species such as algae-eating parrotfish, allowing seaweed to overtake the reefs. In the U.S., the lionfish population is continuing to grow and increase its range. This is largely because lionfish have no known predators and reproduce all year long; a mature female releases roughly two million eggs a year.
difference between uniform velocity and variable velocity
Explanation:
when a body covers equal distance in equal interval of timein a specific direction it is said to have uniform velocity . when a body covers unequal distance in equal interval of time in a specified direction , it is said to have variable velocity .1) How many valence electrons are in the alkaline earth metal family? Do
they form cations or anions?
A)
1 valence electron, cations
B)
1 valence electron, anions
C)
2 valence electrons, cations
D)
2 valence electrons, anions
Answer:
Below
Explanation:
Alkaline earth metals have 2 valence electrons, which means that when they react with other elements, they will lose rather than gain their 2 electrons making them positive ions or cations.
So the correct answer to your question would be....
C) 2 valence electrons, cations

A stone falls from the top of a building and hits the ground at a speed of 32 m/s.
The air resistance force on the stone
is very small and may be neglected.
Calculate the time of fall.
Answer:
Explanation:
first you would need the height of the building in meters then using the formula calculate 32 m/s ÷ the height of the building in meters and you will get your answer

PLEASE HELP AM GIVING 20 POINTS A worker in a factory has discovered a material that is confusing. It can be stored in a container but can also flow from one container to another. It forms powder after some time. The worker is confused and does not know which state of matter it belongs. As a student of Physics, prepare a message that will help the worker in the factory to properly classify the substance in the right state of matter.
The factory worker need to know is the state of the material at room temperature and atmospheric pressure.
Matter is anything that has mass and occupy space. Everything around is composed of matter. The material can easily be classified by considering the state of matter in which the material is found at room temperature and atmospheric pressure.
Hence, all the factory worker need to know is the state of the material at room temperature and atmospheric pressure. This will tell us whether it is a liquid, solid or gas.

What is F = m x a in Newton's laws of motion?
Answer:
This is Newton's second law.
Newton's second law text:
(If a resultant force acts on a body, then an acceleration will give it an acceleration, the magnitude of which is directly proportional to the amount of the net force, and a direction is in the direction of the net force itself)
F=ma
net force = mass x acceleration
