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.

What do the key differences between RNA and DNA mean for the spread of these types of viruses?
Answer:
DNA viruses contain usually double‐stranded DNA (dsDNA) and rarely single‐stranded DNA (ssDNA). These viruses replicate using DNA‐dependent DNA polymerase. ... Compared to DNA virus genomes, which can encode up to hundreds of viral proteins, RNA viruses have smaller genomes that usually encode only a few proteins.
Explanation:
hope it helps my dear friend.
Answer:
Difference Between DNA & RNA Viruses
A virus can self-replicate inside a host cell. ... The viruses that contain DNA as their genetic material are called the DNA viruses. RNA viruses, on the other hand, contain RNA as their genetic material. DNA viruses are mostly double-stranded while RNA viruses are single-stranded

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:

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.

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.

Explanation:
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.

What is the crest and trough of a wave?
Answer:
Explanation:
A crest point on a wave is the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point in a cycle. When the crests and troughs of two sine waves of equal amplitude and frequency intersect or collide, while being in phase with each other, the result is called constructive interference and the magnitudes double (above and below the line). When in antiphase – 180° out of phase – the result is destructive interference: the resulting wave is the undisturbed line having zero amplitude.

Use the reading below to answer the question.
The layer of soil above the permafrost is too shallow for plants with deep roots to live. Grasses and shrubs can survive there because they have shallow roots. A sheet of mosses and lichens grows beneath these plants. When the soil above the permafrost thaws, the soil becomes muddy. Muddy soil is an excellent place for insects, such as mosquitoes, to lay eggs. Many birds spend the summer in the tundra to feed on these insects.
Based on the passage, what is one reason for the lack of trees in the tundra?
A.

B.
amount of rainfall
C.

If an object is placed in water and has a density of 1.9 g/ml will the object float or sink?
Answer:
float
Explanation:
since everything that have a density more than 1g/l (not g/ml) will sink and less than that will float
then 1.9g/ml < 1g/l
Answer:
it would sink
Explanation: it would sink because the density of water is 0.997 m/ml and 1.9 is more then that
