Answer
Rotating
Explanation:
The Earth is always being pulled towards the Sun by gravity.
The Earth is not moving fast enough to "escape" the Sun's gravity and leave the solar system, but it is going too fast to be pulled into the Sun. Therefore, it keeps going around and around( roating)- orbiting the Sun.
Answer:
Rotating around the sun
Flood waters
moving soil from
one location to
another
What is it weathering, Erosion or deposition
Answer:
I think the answer is EROSION because it has to do with the movement of sediment.
Explanation:
Hope this helps!
Flood waters moving soil from one location to another is called erosion.
Erosion is the process by which soil, rock, and other materials are transported from one place to another by natural forces such as water, wind, and ice.
In the case of soil being moved by flood waters, the water is the natural force that is causing the erosion. The water is carrying the soil from one location to another, which is a characteristic of erosion. Deposition, on the other hand, is the process by which eroded materials are deposited or laid down in a new location. Deposition occurs when the energy of the transporting medium (such as water or wind) decreases, and the materials being transported are no longer able to be carried.Therefore, the movement of soil from one location to another due to flood waters is an example of erosion.

Which sentence uses pasteurize correctly?
The painter must pasteurize the scene in pastel colors.
The cows were put in the field to pasteurize.
They pasteurize the juice to make it safe to drink.
We decided to pasteurize the documents for safekeeping
Answer: C
Explanation: They pasteurize the juice to make it safe to drink.
The sentence which uses pasteurization correctly is that they pasteurize the juice to make it safe to drink.
What is pasteurization?Pasteurization or pasteurisation is a process of food preservation in which packaged and non-packaged foods (such as milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. The process is intended to destroy or deactivate microorganisms and enzymes that contribute to food spoilage or risk of disease, including vegetative bacteria, but most bacterial spores survive the process.
The process is named after the French microbiologist Louis Pasteur whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine.Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries to achieve food preservation and food safety.

Find the average atomic mass of smithium ?
Answer:
google friend tell me
Explanation:
You will have to look up the isotopic distribution of lithium nuclei. ALL lithium nuclei have 3 positively charged nuclear particles, protons, i.e. Z = 3 . These 3 particles give rise to the element's identity. If you take the weighted average of ALL lithium nuclei, we get an average mass of 6.941 g⋅mol−1

The half-life of a radioisotope
a
gets shorter with time
b
is constant
c
get shorter with increasing temperature
d
decreases by a factor of two each time
e
become longer over time
Answer:
b is constant
Explanation:
The half-life of a radioisotope is constant throughout its life cycle.
Half-life is the time taken for half of the radioactive nuclei to disintegrate.
Every radionuclide has its characteristic half-life and it is independent of the number of radioactive atoms.
The half-life does not depend on any variable. It is an inherent property of a radioactive isotope. The shorter the half-life, the faster a radionuclide decays. Nuclides with a long half life are fairly stable for a long period of time. The decay of a radioactive element is usually characterized by its half-life.Therefore, the most ideal statement about half-life is that it is constant.
What happens when the number of particles in an atom is changed
Answer:
When the number of particles, though in this case I think you mean (electrons), changes in an atom....it become an ion. Ions are atoms that were chnaged by losing or gaining an electron. If an atom gains an electron it will have a negative charge. If an atom loses an electron it will have a positive charge. Hope this was helpful!!

Which is not an example of an element ?
Answer:
include all compounds.
Answer:
CO2 is a pure compound
Explanation:
Element non examples include all compounds, which are substances made when two different types of atoms form a chemical bond. Any material made by mixing elements is no longer an element. Anytime you see a chemical formula with more than one element symbol in it, it's an element non example.Pure elements are Substances which are made up of only one kind of atom. Air is a mixture of element and compound whereas alcohol in water is a mixture of compounds. CO2 is a pure compound and not an element.
what is the total charge of 20 electrons in zeka-Coulombs?
Answer:
[tex]3.2\times 10^{-18}\ C[/tex]
Explanation:
No of electrons, n = 20
We need to find the total charge. We can use quantization of electric charge in this case.
Net charge,
q = ne
e is charge on an electron
[tex]q=20\times 1.6\times 10^{-19}\\\\q=3.2\times 10^{-18}\ C[/tex]
So, there are [tex]3.2\times 10^{-18}\ C[/tex] of charge in 20 electrons.

to what direction does the rope move?
Answer:
This question appears incomplete
Explanation:
However, the direction in which the tension acting on the rope is directed is the direction the rope will move. Hence, when a rope is attached to an object, the rope will only "realistically" move in the opposite direction because the rope cannot push an object but can only pull an object, hence can only move in the direction away from the object.
NOTE: Tension can be defined as the pulling force of an object through the use of a string, chain or anything with a potential to stretch fully.
