What is the kinetic energy of a 4,000 kg elephant that is running at 2 m/s? What is the kinetic energy of the elephant if it running at 4 m/s? How do the two kinetic energies compare with one another?
By definition of kinetic energy,
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.
Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.
Kinetic energy is represented by the following expression:
Ec = ½ mv²
Where Ec is kinetic energy, which is measured in Joules (J), m is mass measured in kilograms (kg), and v is velocity measured in meters over seconds (m/s).
In this case, you know:
m= 4000 kgv1= 2 m/sv2= 4 m/sThen:
Ec1 = ½ mv1²
Ec1= ½ 4000 kg× (2 m/s)²
Ec1= 8000 J
and
Ec2 = ½ mv2²
Ec2= ½ 4000 kg× (4 m/s)²
Ec2= 32000 J
You can see that the kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.
In summary:
the kinetic energy of a 4,000 kg elephant that is running at 2 m/s is 8000 Jthe kinetic energy of a 4,000 kg elephant that is running at 4 m/s is 32000 Jthe kinetic energy at a speed of 4 m/s quadruples with respect to the speed of 2 m/s.Learn more about kinetic energy and mechanical energy:

Part 1
Show and Explain Sportsmanship during physical activity from a teammate. Think back to a time when a teammate displayed good and bad sportsmanship. Use the Sportsmanship Organizer an the rubric to guide you.
It’s time to share some experiences!
Think of at least two times you have seen a teammate be a bad sport.
Think of at least two times you have seen a teammate be a good sport.
Create pictures and detailed descriptions of all four examples, including:
the sport that was being played
your age when it happened
who said what
the final outcome of the situation
your thoughts on why things happened the way they did
You can submit the Sportsmanship Organizer or another creative format.
Answer:
.
Explanation:
How should a line look like if an object is at rest(stopped) on a distance-time graph?
10 is all i have
If an object is at rest, then its distance doesn't change as time goes on.
On the graph, the points for each time are all at the same distance. They form a horizontal line.
to prove
please answer if you know
otherwise don't give
Answer:
this is your answer look it once
1. Sketch a picture of the components of a galaxy. Write the name of our galaxy as the title of your drawing.2. Investigation3. Ervin is a current 5th grade student. One weekend he went on a trip to the beach with his family. After arriving at the beach, his mother put sunscreen on him to protect him from the Sun. Ervin and his older brother decided to go swimming in the ocean. While swimming his brother pointed out how large the Sun appeared. Later in the day, the Sun was covered up by dark clouds. When the Sun got covered, Ervin decided to stop swimming.At school on Monday, Ervin’s class was learning about the Sun. Ms. Chabert, his teacher, posed 3 questions to the class. Ervin was excited because he was able to use what he learned about the Sun at the beach to answer each question correctly. Use what YOU know about the Sun to answer the questions that Ervin’s teacher posed to the class. Answer in complete sentences please.A. Is the Sun a star?B. Why does the Sun appear large and bright?C. Is the Sun the largest star in the sky?D. What types of energy does the Sun give off?E. How does energy help us on a daily basis?
What kingdom (Plantae, Fungi, Animalia, or Protista) does each organism belong to? (no links)
Answer:
Plantae: herbs, plants, trees, bushes, grass....
Fungi: yeasts, molds, mushrooms
Animalia: all animals (not prokaryotes nor protists)
Protista: amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds
Answer:
Plantae: Kingdom Plantae
Fungi: Kingdom Eukarya
Animalia: Kingdom Metazoa or Animaliaanimals
Protista: Kingdom Protista
Explanation:
Kingdom Plantae includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae.
The Kingdom Fungi belongs to the domain Eukarya and it includes at least 11 separate groups
All animals are members of the Kingdom Animalia, This Kingdom does not contain prokaryotes or protists
Protists are eukaryotic organisms put simply, protists are all the eukaryotes that are not animals, plants, or fungi.
As a Sun-sized star dies, it puts on an exquisite show, shedding its outer layers into space. How long does this process last?
Thousands of years
Billions of years
Millions of years
An unknown amount of time

"Describe and explain how Mercury might be different if it had the same mass as Earth. *Consider the planet's composition"
Answer:This also means that Mercury's surface gravity is 3.7 m/s2, which is the equivalent of 38% of Earth's gravity (0.38 g). This means that if you weighed 100 kg (220 lbs) on Earth, you would weigh 38 kg (84 lbs) on Mercury.
