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:

What is the cause of most waves and how can this change waves' characteristics?
There are three main factors that affect wave formation: wind velocity, fetch, and duration.
Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
How does the digestive system interact with the following organ systems (circulatory, muscular and nervous system) to maintain homeostasis?
Answer:
The circulatory system breaks down food and gets / absorbs nutrients. The muscular system works to get nutrients to the rest of the body. The nervous system basically controls the digestive system and sends information to the brain.
I'm pretty sure I'm right, but please correct me if I'm wrong! :)
Earth's subsystems are the geosphere, atmosphere, hydrosphere, and biosphere. Energy and matter are transferred when Earth's subsystems interact.
Describe which of Earth's subsystems are involved when a hurricane passes through an area. Explain how these different subsystems affect one another.
Answer:
ok
Explanation:
The Earth is made of several subsystems or "spheres" that interact to form a complex and continuously changing whole called the Earth system. Scale
Processes operating in the Earth system take place on spatial scales varying from fractions of millimeters to thousands of kilometers, and on time scales that range from milliseconds to billions of years.
Examples of instantaneous - breathing; rotation of the Earth; earthquake
Examples of long term - making coal; plate tectonics
Cycles
The Earth system is characterized by numerous overlapping cycles in which matter is recycled over and over again. Cycles involve multiple spheres and systems interactions.
Examples of cycles: day and night; rock cycle; seasons
Energy
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.
Humans and the Earth System
People are part of the Earth system and they impact and are impacted by its materials and processes.
Which sentences in the passage are true?
Georgia is a flood-prone area. Storm cellars and tornado-resistant structures would help mitigate the flooding. Desalinizing water would also be ideal in this situation. Georgia could use more satellites and radars to help with detection. Building dams and levees would help control the floodwaters.
Answer:
True: Georgia is a flood-prone area. Building dams and levees would help control the floodwaters.
False : Storm cellars and tornado-resistant structures would help mitigate the flooding. Desalinizing water would also be ideal in this situation. Georgia could use more satellites and radars to help with detection.
Explanation:
pls mark me brainliest
The following sentences in the passage are true: Georgia is a flood-prone area. Georgia could use more satellites and radars to help with detection. Building dams and levees would help control the floodwaters.
Why does Georgia face floods more often?Georgia is located in a region that is prone to severe weather events, including heavy rainfall and flash flooding. The state is also home to many rivers and streams, which can overflow their banks during periods of heavy rain, causing widespread flooding.
Additionally, Georgia has experienced significant population growth and development in recent decades, which has led to increased urbanization and construction in areas that were previously undeveloped or used for agriculture. This urbanization can lead to increased runoff during heavy rain events, which can exacerbate flooding.
Climate change may also be contributing to more frequent flooding in Georgia and other regions. As global temperatures rise, the atmosphere can hold more moisture, leading to more intense rainfall events and an increased risk of flooding.
Overall, floods are a natural and common occurrence in many parts of the world, including Georgia. By taking appropriate measures to prepare for floods, such as implementing effective flood management plans, improving infrastructure, and educating residents on flood risks and safety measures, communities can reduce the impact of flooding on people and property.
Here in the question.
The following sentences in the passage are true:
A. Georgia is a flood-prone area.
D. Georgia could use more satellites and radars to help with detection.
E. Building dams and levees would help control the floodwaters.
Note: Storm cellars and tornado-resistant structures would not help mitigate flooding, as they are designed to protect against tornadoes and severe windstorms, not floods. Desalinizing water is not directly related to flood mitigation, as it is a process of removing salt and other minerals from seawater to make it drinkable, which is more relevant to areas that lack access to fresh water.
Therefore, Georgia is a flood-prone area, and Georgia could use more satellites and radars to help with detection.and Building dams and levees would help control the floodwaters are true.

The pressure of a cylinder with the following dimensions: radius 13.9 cm and height 34 cm; has a pressure of 172.9 kPa. If the pressure is reduced to 1.75 atm, what will be the volume of the gas inside the cylinder?
Answer:Experience has shown that several properties of a gas can be related to each other under certain conditions. The properties are pressure (P), volume (V), temperature (T, in kelvins), and amount of material expressed in moles (n). What we find is that a sample of gas cannot have any random values for these properties. Instead, only certain values, dictated by some simple mathematical relationships, will occur.

Explanation:
Air masses are formed when air stagnates for long periods of time over a uniform surface. The characteristic temperature and moisture of air masses are determined by the surface over which they form. An air mass acquires these attributes through heat and moisture exchanges with the surface.
