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.
1.What do you think Sherman is right about?
2.What do you think Sherman is wrong about?
Answer:
Sherman is right about the green used to camoflauge the dragonflies.
He is wrong about them being the **same** dragonflies.
Sherman is correct that the dragonflies were camouflaged using green.
He is mistaken in thinking these are the same dragonfly.
Who was William Sherman?Sherman, who was raised in Ohio in a family with political clout, earned his West Point diploma from the US Military Academy in 1840. In order to pursue private commercial endeavors, he took a break from his military career in 1853.
He took up the role of superintendent of the Louisiana State Seminary of Learning & Military School in 1859; he left it when Louisiana withdrew from the Union. The institution is now known as Louisiana State University. Before to moving to the Western Theater in 1861, Sherman led a brigade of volunteers at the First Battle of Bull Run.
He was stationed in Kentucky where, as a result of his pessimism on the war's prospects, he experienced a breakdown that necessitated a brief period of leave.

How are exothermic and endothermic reactions measured in a lab?
Answer:
Exothermic and endothermic are measured by a calorimeter.
How to tell the difference between them. If change is positive, then thermal energy was released, and the process is exothermic. If the change is negative, then thermal energy was absorbed, and the process is endothermic.

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:

4. Convection in the mantle results in the movement of plates on Earth.
a. TRUE b. FALS
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.

1. Most of the stars on the HR Diagram are classified as which type of star?
2. What is the color of the stars with the lowest surface temperature?
3. What is the color of the stars with the highest surface temperature?
4. Is the surface temperature of white dwarf stars higher or lower than red super giants?
5. What type of star has a low temperature but a high luminosity?
Answer:
1. Main Sequence - middle life 17
2. red
3. blue
4. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16.
5. red giants
Explanation:
Main sequence stars have a Morgan-Keenan luminosity class labeled V. red giant and supergiant stars (luminosity classes I through III) occupy the region above the main sequence. They have low surface temperatures and high luminosities which, according to the Stefan-Boltzmann law, means they also have large radii. White dwarf stars are much hotter than Red Supergiants 15. List the color of the stars from hottest to coldest: Blue, White, Yellow, Orange, Red 16. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body. Most stars, including the sun, are "main sequence stars," fueled by nuclear fusion converting hydrogen into helium. ...
As stars begin to die, they become giants and supergiants (above the main sequence).

Explanation:
In a recent hockey game, one player (m=100kg) was moving at a velocity of 8 m/s when he ran into another player (m=300kg) who was at rest (v=0m/s). After the collision, the two players were stuck together (moving with the same velocity). What was their velocity after the collision?
Their velocity after the collision was 2 m/s.
What is principle of conservation of momentum?
According to the principle of momentum conservation, momentum is only modified by the action of forces as they are outlined by Newton's equations of motion; momentum is never created nor destroyed inside a problem domain.
Given parameters:
one player (m=100kg) was moving at a velocity of 8 m/s initially.
Another player (m=300kg) who was at rest (v=0m/s) initially.
After collision they stuck together and let the velocity of them is v.
According to principle of conservation of momentum, total momentum remains conserved.
total initial momentum = total final momentum
100×8 + 300×0 = (100 + 300)v
400v = 800
v = 2.
Hence, their velocity after the collision was 2 m/s.

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.
