Name the three stress forces that cause changes in Earths crust. Explain how each type of force affects rock.Identify the type of fault that each force produces. This is science i couldnt find a science thing
Answer:
Shear
Tension
Compression
Explanation:
The 3 stress forces are;
-shear
-tension
-compression
1) Shear is the stress force that pushes back a mass of rock in two opposite directions which in turn will produce strike - slip faults.
2) Tension is the stress force that pulls on the crust thereby stretching in a manner that it becomes thinner at its middle which in turn will produce normal faults.
3) Compression is the stress force that makes rocks squeeze until they fold or break and this will in turn produce reverse faults.
What is the relationship between the circulatory and respiratory systems?
A. They work together to store the waste that blood collects from the body.
B. The circulatory system provides oxygen that the respiratory system uses to fill the lungs
C. The respiratory system provides blood that the circulatory system uses to transport nutrients.
D. They work together to supply oxygen to tissues and rid the body of carbon dioxide
Answer:
The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart

The density of H2O2 is 1.407 g/mL, and the density of O2 is 1.428 g/L. How many liters of O2 can be made from 55 mL H2O2
Explanation:
mass H2O2 = 55 mL(1.407 g/mL) = 80.85 g
molar mass H2O2 = 2(1.01 g/mol) + 2(16.00 g/mol) = 34.02 g/mol
moles H2O2 = 80.85 g/34.02 g/mol = 2.377 moles H2O2
For each mole of H2O2 you obtain 0.5 mole of O2 (see the equation).
moles O2 = 2.377 moles H2O2 (1 mole O2)/(2 moles H2O2) = 1.188 moles O2
Now, you need the temperature. If you are at STP (273 K, and 1.00 atm) then 1 mole of an ideal gas at STP has a volume of 22.4 L. Without temperature you are not really able to continue. I will assume you are at STP.
Volume O2 = 1.188 moles O2(22.4 L/mole) = 0.0530 L of O2.
which is 53 mL.

What types of radiation cause the parent isotope to change into a different element?
Answer:
Beta decay is most common in elements with a high neutron to proton ratio. Gamma decay follows the form: In gamma emission, neither the atomic number or the mass number is changed. A high energy gamma ray is given off when the parent isotope falls into a lower energy state.

What is different about the atomic structure of the oxygen isotopes?
Answer:
Each isotope of oxygen contains 8 protons, but differs in the number of neutrons. An isotope number is a shorthand representation of its mass. Because protons and neutrons are roughly equal in mass, an isotope's number is equal to the sum of its protons and neutrons.
Explanation:
Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

Answer:
Sunlight
Explanation:
My science teacher has told us that plants need the sun to photosynthesis. And even though their is a lot of sun, they need to compete for it still.
Where must you be standing if the Sun appears to be directly overhead at noon?
O A. At the South Pole
O B. At the North Pole
O C. At a point somewhere along the prime meridian
O D. At a point somewhere along the equator
Answer:
D
Explanation:
at a point somewhere along the equator
In the case when the Sun appears to be directly overhead at noon should be along with the equator.
What is the equator?It is considered to be the imaginary line that should be arounded with the middle of the planet or the celestial body. It is halfway that lies between the North Pole and the South Pole, at 0 degrees latitude. In the equator, it divides the planet into a Northern Hemisphere and a Southern Hemisphere
Therefore, based on the above explanation, the option d is correct.

explain how to find the mass of water. show your calculations as well
Answer:
You can find the mass of water by multiplying the density of water by its volume.
mass = Density x volume
Explanation:
It is very easy to find the mass of water once you know the formula of density. "Density" refers to mass per unit volume.
Density (ρ) = [tex]\frac{mass}{volume}[/tex]
Therefore, mass = ρ x volume
The density of water is 1 kg/L.
For example, if the volume of water is 500 ml, then you can get its mass by multiplying 500 ml by 1 kg/L.
Let's convert 500 ml to Liter first.
500 ml x [tex]\frac{1 L}{1,000 ml}[/tex] = 0.5 L
Now, let's compute.
mass = ρ x volume
mass = 1 kg/L x 0.5L
mass = 0.5 kg
The mass of a 500-ml water is 0.5 kg.

which description shows copper at rtp?
a) stationary and closed together
b) stationary and randomly arranged
c)vibrating and in a regular arrangement
d) vibrating and in a random arrangement
Answer:
c)vibrating and in a regular arrangement
Explanation:
Copper is a chemical element represented by the symbol Cu and having atomic number 29. Copper is a transition metal which means its subshells are not completely filled and that is why they are vibrating in the room temperature. But copper is a solid at room temperature with regular arrangement of atoms.
Hence, the correct answer is "c)vibrating and in a regular arrangement".
