Answer:
C. Earthquake
Explanation:
Earthquake is a likely result of the slippage along this fault boundary.
At a transform margin, rocks are moving parallel to one another. This often causes a slippage that leads to the generation of earthquakes.
An earthquake is a sudden displacement within the earth that leads to a sudden release of energy in all direction. The slippage on the surface of a transform fault often lead to earthquakes.Answer:

If a sample of nitrogen gas is compressed to fit in a smaller container, what happens to the
pressure, assuming the temperature remains constant?
Answer:
The pressure increases
Explanation:
In this action it is best to apply Boyle's law to resolve the problem. This is an interplay between Volume, Pressure and Temperature.
According to Boyle's Law "the volume of a fixed mass of a gas varies inversely as the pressure changes, if the temperature is constant". Since the volume is being reduced to cram into the container, the pressure of the gases increases. In the smaller container, pressure rises and the volume reduces if temperature remains constant.Down a group, the electron shielding tends to________
a.)increase
b.)decrease
thank uuu :)
Answer:
A
Explanation The number of energy levels (n) increases, and so does the distance between the nucleus and the outermost orbital. The increased distance and the increased shielding weaken the nuclear attraction, and so an atom can't attract electrons as strongly.

The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics?
Answer:
The validation of seafloor spreading in the 1950s and 60s
Explanation:
The theory of seafloor spreading was supported by numerous evidence including thermal probes that showed that heat flow over the mid-ocean ridges measured up to four times those measured in general bottom sediments, which are taken as due to the presence of molten Earth material close to the ridge crest
The ridge crest also show signs unusually seismic wave velocities that are considered to be due to microfracturing and thermal expansion from upwelling magma

Explanation:
How does more greenhouse gases in the Earth's atmosphere affect earth's temperature?
Explanation:
Greenhouse gasses in Earth's atmosphere affect Earth's temperature by making it hotter. Greenhouse gasses make the Earth warmer by trapping heat. You can think of greenhouse gasses as Earth's blanket.
Answer:
It effects the earth when we have more greenhouse gasses in the earth's atmosphere because it makes the earth more warmer which will cause more sunlight to hit earth because there is more heat near the earth's surface, and this will cause the temperatures to rise really high because of the heat.

Explanation:
The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Symbol: NO3) for a total formula weight of 62.05. Lead Nitrate is generally immediately available in most volumes.
Why are ions usually formed during the interaction of metal with nonmetal and not between two metals?
Explanation:
Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.
This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.
Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.

how can you find the Frequency if you only have the wavelength? can you solve this example what is the Frequency of the wavelength 4km? can you please show your steps thanks.
Answer:
75000 Hz
Explanation:
f = V / λ (f= frequency, v=velocity of wave, lambda= wavelength)
alternatively, f = c / λ (f= frequency, c= speed of light- 3.00x10^8 m/s, lambda= wavelength)
f= [3.00x10^8 m/s]/[4000 m]
=75000 Hz

Sucrose is an organic compound made by plants for quick energy. What type of organic compound is sucrose?
1-protein
2-carbohydrate
3-lipid
4-nucleic acid
Answer:
2-carbohydrate
Explanation:
Sucrose belongs to the carbohydrate family. It is a disaccharide which is derived from the condensation of glucose and fructose.
In the body, they are sources of energy for living processes. Upon hydrolysis such disaccharide produces tow monosaccharide units. Food substances that are energy rich will contain some of these organic molecules.Sucrose is a specific type of organic compound classified as a carbohydrate and the correct option is option 2.
Carbohydrates are essential biomolecules made up of carbon, hydrogen, and oxygen atoms. Sucrose, also known as table sugar, is a disaccharide formed by the chemical bonding of one glucose molecule and one fructose molecule.
Plants produce sucrose through photosynthesis and use it as a readily available source of energy. When consumed by animals, including humans, sucrose is broken down into its constituent monosaccharides to provide fuel for various cellular processes.
Thus, the ideal selection is option 2.

Biologists designed an experiment to test the effect of compost on the development of root crops. They tested several different crops, including carrots, potatoes, beets, and onions. They grew most of the plants in the greenhouse, but due to space issues, they had to grow some outdoors. They gave all the plants the same amount of compost. They obtained the compost from a local farmer and from the local hardware store. They ran out of the farmer’s compost, so some of the plants received that compost when the seeds were planted and other plants got hardware store compost after the plants had already started growing.
RESULTS: Some of the roots seemed really big. Other roots seemed normal or small.
CONCLUSION: They couldn’t tell what the effect of the compost was because the results were inconsistent.
What are five problems with this experimental design that could have caused inconsistent results?
Answer:
it is 56
Explanation:
Answer:
one of the problems are that sum of the plants weren't getting the same kind of compost the second issue is that they couldn't fit all the plants into the greenhouse third issue issue was that some plants got compost when planted but what about the others

Someone knows how to solve this? It was found that 0.0005 mol of Ca (OH) 2 dissolved in 100 cm3 of solution is 80% dissociated. Calculate the pH of this solution.
Answer:
pH = 11.9
Explanation:
First, we determine the number of OH⁻ moles dissolved:
80% of Ca(OH)₂ is dissolved:
0.0005 mol * 80/100 = 4x10⁻⁴ mol Ca(OH)₂There are two OH⁻ moles per Ca(OH)₂ mol:
4x10⁻⁴ * 2 = 8x10⁻⁴ mol OH⁻Now we can calculate the molar concentration of OH⁻ (moles/L):
100 cm³ = 100 mL100 mL ⇒ 100/1000 = 0.1 L[OH⁻] = 8x10⁻⁴ mol / 0.1 L = 8x10⁻³ MThen we calculate the pOH of the solution:
pOH = -log[OH⁻] = -log(8x10⁻³ M) = 2.10Finally, we can calculate the pH of the solution using the equation
pH + pOH = 14pH = 14 - pOH = 14 -2.10pH = 11.92. Leaves turning brown in the fall

What pressure is required to compress 200 liters of air at 100 atmosphere into a
cylinder whose volume is 20.0 liters?
Answer:
P₂ = 1000 atm
Explanation:
Given data:
Initial volume of air = 200 L
Initial pressure = 100 atm
Final volume = 20.0 L
Final pressure required = ?
Solution:
The given problem will be solved through the Boly's law,
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
100 atm × 200 L= P₂ × 20.0 L
P₂ = 20,000 atm. L/ 20.0 L
P₂ = 1000 atm
Practitioners of the branch of alternative medicine known as homeopathy claim that very dilute solutions of substances can have an effect. Is the claim plausible? To explore this question, suppose that you prepare a solution of a supposedly active substance, X, with a molarity of 0.10 molL1 . Then you dilute 10. mL of that solution by doubling the volume, doubling it again, and so on, for 90 doublings in all. How many molecules of X will be present in 10. mL of the fi nal solution? Comment on the possible health benefi ts of the solution.
Answer:
a. 4.865 × 10⁻⁷ molecules. b. The possible health benefits of the drug might be minimal or non-existent.
Explanation:
a. Since we have 0.10 mol/L and 10 mL of solution, the number of moles in 10 mL of solution is n = CV where C = concentration and V = Volume. C = 0.10 mol/L and V = 10 mL = 0.01 L.
So n = CV = 0.10 mol/L × 0.01 L = 0.001 mol.
Since the initial volume of the solution is 10 mL and doubled, it is 2 × 10 mL = 20 mL. It is doubled again to 2 × 20 mL = 40 mL. It is doubled again to 2 × 40 mL = 80 mL. Our third doubling is thus 80 mL = 2 × 2 × 2 × 10 mL = 2³ × 10 mL. So the volume for our nth doubling is V = 2ⁿ × 10 mL. So four our 90 th doubling, the volume is V = 2⁹⁰ × 10 mL = 2⁹⁰ × 10 mL
Since we have 0.001 mol present, the concentration in this new volume is thus C' = 0.001 mol/2⁹⁰ × 10 mL.
So the number of moles in 10 mL of this solution is thus n = 0.001 mol/(2⁹⁰ × 10 mL) × 10 mL = 0.001/2⁹⁰ mol
To find the number of molecules of X present we use, number of moles, n = number of molecules, N/Avogadro's number of molecules, N'
n = N/N'
N = nN'
= 0.001/2⁹⁰ mol × 6.022 × 10²³ molecules/mol
= 8.078 × 10⁻³¹ × 6.022 × 10²³
= 48.65 × 10⁻⁸
= 4.865 × 10⁻⁷ molecules.
b. Since the number of molecules of X present in 10 mL solution of the final diluted solution is 4.865 × 10⁻⁷ molecules, this shows that the number of molecules of X is very little so, the possible health benefits of the drug might be minimal or non-existent.
