Answer:
D
Explanation:
Remember that magnets only attract at different poles. If both poles are the same, they repel
2 -An invasive species is a species that is not native to a specific location (an introduced species), and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.[2]
The term as most often used applies to introduced species that adversely affect the habitats and bioregions they invade economically, environmentally, or ecologically. Such species may be either plants or animals and may disrupt by dominating a region, wilderness areas, particular habitats, or wildland–urban interface land from loss of natural controls (such as predators or herbivores). This includes plant species labeled as exotic pest plants and invasive exotics growing in native plant communities.[3][4][5][6] The European Union defines "Invasive Alien Species" as those that are, firstly, outside their natural distribution area, and secondly, threaten biological diversity.[7][8] The term is also used by land managers, botanists, researchers, horticulturalists, conservationists, and the public for noxious weeds.[9]
To solve for the thickness of the latter of oil, we can
simply divide the volume by the total surface area:
Thickness = Volume / Surface Area
We are both given the volume and the surface area, all we
have to do now is to convert the units in like terms so that we can cancel
those out.
Surface Area = 0.50 acres (1.0 x 10^4 m^2 / 2.47 acres)
Surface Area = 2,024.29 m^2
Further converting this into cm:
Surface Area = 2,024.29 m^2 (100 cm / m)^2
Surface Area = 20,242,914.98 cm^2
Therefore the thickness is:
Thickness = 5.0 cm^3 / 20,242,914.98 cm^2
Thickness = 2.47 x 10^-7 cm
or
<span>Thickness = 2.47 x 10^-9 m = 2.47 nm = 24.7 A</span>
Answer: A. The total displacement divided by the time and C. The slope of the ant's displacement vs. time graph.
Explanation:
Hi! The question seems incomplete, but I found the options on the internt:
A. The total displacement divided by the time.
B. The slope of the ant's acceleration vs. time graph.
C. The slope of the ant's displacement vs. time graph.
D. The average acceleration divided by the time.
Now, since we know the ant is travelling at a constant speed, its average velocity 
will be expressed by the following equation:
Where:
is the ant's total displacement
is the time it took to the ant to travel to the kitchen
Hence one of the correct options is: A. The total displacement divided by the time
On the other hand, this can be expressed by a displacement vs. time graph graph, where the slope of that line leads to the equation written above. So, the other correct option is:
C. The slope of the ant's displacement vs. time graph.
Batteries supply electrons to the circuit by releasing negatively charged atoms or ions. These ions are produced by the batteries through a chemical reaction that spontaneously occurs within the battery. So the negative end of the battery pushes the ions towards the positive end of the circuit with the help of the voltage. This is why eventually, batteries "run out" when the electrode is used up and the chemical reaction can no longer continue.
