How does burning carbon-containing fuels contribute to Earth’s climate change problem?
The chemical reaction that happens when ethanol and oxygen mix produces two substances: carbon dioxide and water in the gas phase. Since both of these are invisible, colorless gases, it seems like nothing is left of the liquid that was in your gas tank. However, the atoms of the reactants haven’t disappeared at all—they’ve only rearranged to form the products. The carbon dioxide and water produced by this chemical reaction enter the atmosphere whenever we burn ethanol or other carbon-containing fuels. In the recent past, humans have increased the amount of carbon dioxide in Earth’s atmosphere by burning such fuels, resulting in widespread changes to Earth’s climate. In response to these effects, scientists are working to find fuels that can release energy without producing carbon dioxide.
Answer:
"Carbon dioxide (CO2) is one of a number of gases that are transparent to the visible light falling on the Earth from the Sun, but absorb the infra-red radiation (heat) emitted by the warm surface of the Earth, preventing its loss into space. During the geological history of the Earth the level of atmospheric CO2 has varied considerably and this has had an impact on the global temperature. A significant amount of this atmospheric carbon was sequestered or (removed from the atmosphere) and turned into inert material (coal, and oil) typically 300-360 Million years ago. All of the global ecosystems and species have adapted to a lower level of atmospheric CO2 and critically, human civilisation has also grown since that period. Since the industrial revolution humans have been burning sequestered CO2 in the form of coal, oil, and natural gas which has the result of releasing energy but also releases CO2 back into the atmosphere".

An airplane touches down on the runway at 37 m/s after 8 seconds, the airplane has slowed to a velocity of 5 m/s. what is a plane's acceleration?
Answer:
The acceleration is positive because they’re speeding up 4. An airplane touches down on the runway at 37m/s. After 8 seconds, the airplane has slowed to a velocity of 5 m/s.
Explanation:
Answer:
[tex]\boxed {\boxed {\sf a= -4 \ m/s^2}}[/tex]
Explanation:
Acceleration is the rate at which an object changes its velocity. It is the change in velocity over the change in time.
[tex]a= \frac{ \Delta v}{\Delta t}[/tex]
The change in velocity is the difference between the final velocity and the initial velocity.
Δv= final velocity - initial velocityThe airplane touches down at 37 meters per second, the slows to 5 meters per second. The final is 5 m/s and the initial is 37 m/s.
Δv= 5 m/s - 37 m/s= -32 m/sThe change in time is also how much time it took for the velocity to change. In this case, the change in time is 8 seconds.
Now we know the values for the variables:
Δv= -32 m/s Δt= 8 sSubstitute the values into the formula.
[tex]a= \frac{-32 \ m/s}{8 \ s}[/tex]
Divide.
[tex]a= -4 \ m/s /s[/tex]
[tex]a= -4 \ m/s^2[/tex]
The acceleration is -4 meters per square second. Since the acceleration is negative, the airplane is slowing down.

Answer:
Model B
Explanation:
Model A shows that light has been reflected, whereas Model B shows the light has been refracted. Light will be refracted as the light enters a more dense medium (glass), from a less dense medium (air).
This website has a really useful, thorough explanation for why this occurs:

Explanation:
1. How can systems with such different structures perform the same function?
2. How can different structures perform the same function?
Please help! And explain your answer with evidence please!
Explanation: Specialized Structures. ... This is because different organisms have developed unique structures that perform these functions and that do so in ways that fit their specific environments. So in this case, the structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Due to unique structure an organism perform similar function if the structures are different.
Different structures perform the same function because different types of organisms have developed unique structures that helps them to perform function that is specific to their environments. The structures are specialized to perform a specific function but also to fit the needs of a specific organism.
Analogous structures refers to those structures which perform same function, but have different structures. Such type of organisms belongs to different ancestry but their body parts perform similar function so we can conclude that due to unique structure an organism perform similar function if the structures are different.

The diffrents between an element molecule and a compond molecule is the type of atoms with whitch it is made true or false.
Answer:
true
Explanation:
because an element is of one type of an atom.
A molecule is made of two or more atoms held together by chemical bonds and if two atoms that form a molecule are of the same element form a diatomic molecule.
A molecule that consists of two or more atoms of different elements it forms a chemical compound.

Explain how convection currents drive tectonic plate movement. In your answer, describe the role of energy transfer in the movement of tectonic plates.
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading
Answer:
The convection currents are what causes the movement of the tectonic plates. These currents occur in the mantle layer. Basically, the convection currents are a circular movement of the magma in the mantle which is cause by the difference in temperature and density. The hotter magma moves up because it is less dense, while the cooler magma moves down because it is more dense. This movement continues all the time. The magma that moves up comes in touch with the crust above it. At certain places where the crust is thinner, or there are cracks, under the big pressure from the mantle, the magma manages to penetrate through it, filling up the gaps, and also pushing the plates away. As the plates are pushed more and more, their opposite ends collide with other plates, resulting in subduction, so the crust is getting into the mantle and melts, moving down in the mantle as it is becoming cooler and denser magma, and the process continues on and on.
