Why is it important to know how the sun's energy affects the lower atmosphere if you are planning to harness the power of moving air?
Answers
It is important to know the affects of temperature on pressure and thereby on winds. At high temperature, the pressure will be high and thus, the winds will pass from that area.
What is winds?
Wind is the passage of air through the atmosphere. The uneven distribution of temperature leads to the difference in pressure. The pressure gradient results in wind.
Air pass from high pressure area to low pressure area. According to Gay- Lussacs law, at the pressure gases is directly proportional to the temperature.
Hence, as the temperature increases, pressure in that area increases, leads to air currents to the opposite direction. This will definitely affects harnessing.

The forces from below the surface that change the surface of the earth are
Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers
Answers
Correct! The forces from below the surface that change the surface of the Earth include:
1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

Answer:
Inertia- the tendency of an object to resist a change in velocity

Witch statement correctly compares the masses of subatomic particles in an atom such as carbon
Answers
Answer: The statement that correctly compares the masses of subatomic particles in an atom such as carbon is "The mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron." This is because an atom such as carbon is composed of protons, neutrons, and electrons. Protons and neutrons are approximately the same mass and are much more massive than electrons. Therefore, the mass of a neutron is slightly larger than the mass of a proton, and the mass of an electron is much smaller than that of a proton or neutron.

When a chemical reaction does not occur, what happens to the atoms of the two substances? Provide an example from Sim as evidence to support your answer.
Answers
An example of this can be seen in the Sim on Amplify, where students can experiment with different chemical reactions. For instance, in the "Chemical Reactions" Sim, students can explore the reaction between iron and sulfur to form iron sulfide. In this reaction, the iron atoms and sulfur atoms combine to form a new compound, iron sulfide, with different properties than the original iron and sulfur. The atoms of the iron and sulfur are rearranged to form new bonds, resulting in the formation of a new substance. This is an example of a chemical reaction, where the atoms of the two substances are rearranged to form a new compound with different properties.
Answer:
Explanation:A chemical response is a chemical transformation in which two chemicals combine to create a third component.
(i) Adding diluted acid to an active metal causes the test tube to heat up and hydrogen gas to escape, which results in the production of heat.
(ii) When diluted hydrochloric acid is added to silver nitrate, AgCl, a white precipitate, results.
(iii) When water is added to quicklime, the mixture boils and produces heat along with a hissing sound.
(iv) Thermal breakdown of mercury oxide - Mercury turns from red to a metallic silver tint as a result of this process.

Answers
Explanation:
need points bye have good day
Answer:
CH4+2O2→CO2+2H2O
Explanation:
Start with the least common atoms and leave things like H and O to the end.
You need to have the same number of methane reactants as carbon dioxide products because there is one carbon in each. I’ll set them both to 1 for now. O see two things with oxygen on the product side so we will have to juggle numbers a bit to figure out those. There is only H in the water so we’ll go there next. One CH4 gives 2 water molecules so we have that done now. At last we can tackle the O atoms. In two waters there are 2 and in the CO2 there are two more so a total of 4 O atoms in the products so we need two O2 molecules in the reactant side.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

Nicole has 2 glasses on the counter: one of water and one of sugar-water. She is baking a cake and needs to use the sugar-water for the glaze. Both glasses look identical, but one contains a mixture and the other contains a compound.
Is sugar-water a mixture or a compound? Define mixtures and compounds, and explain how, without tasting it, Nicole can test to make sure she is using the sugar-water in the glaze.
Answers
Answer:
sugar-water is a mixture not a compound.(homogeneous mixture.)
Explanation:
Compounds are substances formed by the chemical combination of two or more elements. Mixtures are substances formed by physically mixing two or more substances together.
The solution of sugar in water is considered a mixture not a compound because the particles of sugar and water are not completely dissolve nor mixed in a fixed proportion or ratio. hope this helped :)
Answer: Nicole can take a small amount of sample from both of the glasses, she can place the samples in two separate containers and leave them out in the sun, so that the water gets evaporated. One of the two containers will contain a residue of sugar. The one containing the sugar residue, is the sugar-water solution.

Which of the following best explains the relationship between peak-to-peak amplitude and semi-amplitude?
Answers
Answer:
A. Semi-amplitude is half the distance of the peak-to-peak amplitude
Explanation:
The correct answer is : The semi-amplitude is half the distance of the peak-to-peak amplitude (option A). The peak-to-peak amplitude is the total distance between the highest positive peak and the lowest negative peak in a waveform. It represents the full range of variation in the amplitude of the waveform.
The peak-to-peak amplitude of a waveform is the measurement of the total distance between the highest positive peak and the lowest negative peak. It provides information about the full range of variations in the amplitude of the waveform. Mathematically, it is calculated by subtracting the minimum value from the maximum value of the waveform.
