Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the choices provided A B C D
Answers
Answer:
A. 14.59
Explanation:
Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.
Next, we have to know that to round a number;
* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.
* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit
Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant
Hence, 14.587020 will be:
= 14.587020
= 14.58700
= 14.59000
We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right
Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

9. A section of a topographic map is shown below. X- 1600 1500 1400 1300 Contour interval: 20 m 1200- What is the difference in elevation in meters between Point X and Point Y on the map?
Answers
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
the elevation is increasing from southeast toward northwestthe difference in elevation between the contour lines is 20 mthe difference in elevation between the main contour lines is 100 mPoint X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

b. basalt, andesite, dacite, rhyolite
c. Volcanoes have a crater at the summit formed around a vent through which lava, steam, ashes, etc. are expelled.
2. Mythology was often used by ancient cultures to explain natural phenomena, including volcanoes. Volcanoes have the power to create and destroy, which would have been awe-inspiring to people in ancient times. By creating stories and legends around volcanoes, ancient cultures were able to explain their behavior and attribute their power to the gods or other supernatural beings, thus giving people a sense of control and understanding.
3. Rift volcanoes are volcanoes that form along the boundaries of tectonic plates, where magma rises up to the surface and creates a linear series of volcanic vents. They are typically located along mid-ocean ridges and are characterized by eruptions of fluid basaltic lava. Cinder cones are small, steep-sided volcanoes that are formed from explosive eruptions of gas-charged magma. They are typically less than 300 meters high and are made up of loose pyroclastic debris.
4. Pyroclastic rocks are rocks that are formed from the consolidation of volcanic fragments that were explosively ejected during an eruption. They are composed of different types of materials such as ash, pumice, and volcanic bombs. Pyroclastic rocks can be deposited in various ways, such as air fall deposits, pyroclastic flows, and lahars.
5. There are three main types of volcanoes: shield volcanoes, stratovolcanoes (or composite volcanoes), and cinder cones. Shield volcanoes have broad, gently sloping sides and are made up of fluid lava flows. Stratovolcanoes are tall, steep-sided volcanoes that are formed from explosive eruptions of viscous lava and pyroclastic debris. Cinder cones are small, steep-sided volcanoes that are formed from explosive eruptions of gas-charged magma.

Discuss some of the trends in the periodic table; what they are, how each can be determined, and what each trend tells us about the structure of the atom of an element in relation to its location on the Periodic Table. Please touch on at least 4 of the 6 trends listed: atomic number, atomic mass, Group #, Period #, Oxidation #, and electronegativity.
Answers
Answer:Major trends are electronegativity, ionization energy, electron affinity, atomic radius, and metallic character. The existence of these trends is due to the similarity in atomic structure of the elements in their group families or periods and because of the periodic nature of elements
Electronegativity, ionization energy, electron affinity, atomic radius, and metallic character are key trends. Due to the periodic nature of elements and their identical atomic structures throughout their group families or eras, these tendencies are present.
What is the periodic table?
A periodic table is an orderly list of all chemical elements in order of increasing atomic number or the total number of protons in an atomic nucleus. It is used in chemistry.
The "periodic rule," which describes a recurrent pattern in which elements in the same column (group) exhibit comparable characteristics, is present when the chemical elements are grouped in this way. Dmitry I. Mendeleyev's original discovery, which was discovered in the middle of the 19th century, has had immeasurable significance for the advancement of chemistry.
Therefore, significant trends include those in electronegativity, ionization energy, electron affinity, atomic radius, and metallic nature. The similarities in atomic structure between the elements in their group families or periods and the periodic nature of elements account for the presence of these patterns.

Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

Explanation:

BECAUSE
A simile is a statement that is saying 2 or more things are alike using the words “like” or “as”
A metaphor is the same thing except they DON’T use the words “like” or “as”
A analogy is saying 2 or more things are DIFFERENT, not SIMILAR, so just about the opposite of a metaphor or simile.

Answer: Encourage students to set up a germination experiment by placing the seeds in different conditions, such as light vs. dark, or wet vs. dry. Moreover, they need to pot the same seed in more than one pot.
Explanation:
This option provides a clear and practical approach to the seed germination investigation. By setting up different conditions for the seeds, such as light vs. dark or wet vs. dry, the students can observe and compare how these conditions affect the germination process. Additionally, potting the same seed in multiple pots allows for a controlled comparison within the experiment.
By manipulating these variables, the students can gather valuable data and observations regarding the influence of light and moisture on seed germination. This approach promotes a hands-on and investigative learning experience, encouraging students to actively engage with the scientific process while documenting the changes that occur over time, such as the emergence of roots and shoots.
When reading about the history of science, you often learn about individual people and the amazing things they discovered or invented. However, when learning about experiments from long ago, you might not agree with the methods used at the time. If scientists repeated the experiments today, they would probably make some changes in how they are carried out.
