B.)An existing theory is modified so that it can explain both the old and new observations.
C.)An existing theory remains the same because a theory is a proven fact that is always true.
D.)An existing theory is kept unchanged while a new theory is developed to explain the new observations.
Answer:
An existing theory is modified so that it can explain both the old and new observations.
Explanation:
The statement which best describes how an existing theory is often affected by the development of new technology is that an existing theory is modified so that it can explain both the old and new observations.
What is a theory?
Theory is defined as a thoughtful explanation which is provided for observations which is constructed using scientific methods.The theory brings together many facts and hypothesis.
It is called as theory as it provides some set of assumptions initially which provide description to the field's approach to the subject.These are elementary theorems of a particular theory.It is a rational type of thinking about a set of observations.
They may be scientific,or non scientific or have no discipline at all.There are three types of theory:1) scientific, 2)philosophical and 3) moral.It provides explanation regarding the underlying mechanisms .

A graduated cylinder is filled with 54.32 cm3 of water. An irregular solid made of iron is carefully placed into the graduated cylinder. The new volume recorded on the graduated cylinder is 57.65 cm3. The density of iron is known to be 7.874 g/cm³. What is the mass in grams of the irregular solid made of iron?
Answer:
The answer is 26.22 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density of iron = 7.874 g/cm³
volume = final volume of water - initial volume of water
volume = 57.65 - 54.32 = 3.33 mL
We have
mass = 7.874 × 3.33 = 26.22042
We have the final answer as
26.22 gHope this helps you

a plumber
a gardener
a bricklayer
a mechanic
Need answer ASAP
Sodium hydroxide NaOH is proven to be an active agent for improving the mechanical properties of the bricks. Hence, bricklayer most likely need sodium hydroxide.
What is sodium hydroxide?Sodium hydroxide is an ionic compound formed by the metallic sodium and water. Sodium hydroxide has the chemical formula NaOH. It is a strong base and used as a reagent in many chemical synthesis which has to be carried in presence of a base.
Sodium hydroxide has an effect on the drying kinetics of bricks which are made with clay. Studies reported that the drying duration is linearly related with the concentration of NaOH.
Drying duration of bricks layers increases with increase in concentration of NaOH as well as the material porosity decreases. and hence the bricks will not show the visible cracks. Therefore, bricklayer need NaOH.

If an atom has 18 protons,17 neutrons,and 19 electrons what is the atom electrical charge?
A +2
B +1
C -2
D-1
Answer:
D: -1
Explanation:
18 protons so +18
19 electrons -19
neutrons dont count there neutral
-19+18= -1
Answer: D: -1
Explanation: All protons have a +1 charge, neutrons are neutral, and electron have a -1 charge. Therefore it can be concluded that if the atom has 18 protons which all have +1 charge and 19 electrons which all have -1 charge, then the atom will have a -1 charge since 18-19=-1
Do cells in many-celled organisms all look the same or different? Explain.
Cells in many-celled organisms can look the same or different, depending on the type of organism and the function of the cells.
In general,multi-cellular(many-celled) organisms have specialized cells that perform specific functions, such as muscle cells, nerve cells, and blood cells. These cells are different in structure and function, but they all work together to maintain the organism's health and survival.
For example, in humans:
Muscle cells are long and cylindrical, while nerve cells are long and thin with many branches. Blood cells are smaller and come in several different types, such as red blood cells, which carry oxygen, and white blood cells, which fight infection.On the other hand, some cells in many-celled organisms look the same, such as skin cells, which are flat and thin, and line the surface of the skin.Therefore, cells in many-celled organisms can look the same or different, depending on the function of the cells. While many-celled organisms have specialized cells, some cells have the same structure and function.

A chemist prepares a solution of sodium carbonate by measuring out of sodium carbonate into a volumetric flask and filling the flask to the mark with water. Calculate the concentration in of the chemist's sodium carbonate solution. Be sure your answer has the correct number of significant digits.
Answer:
The correct answer will be "[tex]9.45\times 10^{-5} \ mol/L[/tex]".
Explanation:
We have:
Moles of solute (Na₂Co₃) = [tex]18.9 \mu \ mol[/tex]
= [tex]18.9\times 10^{-6}[/tex]
[tex]1 \mu \ mol[/tex] = [tex]10^{-6} \ mol[/tex]
Now,
The volume of the solution will be:
⇒ [tex]0.200 \ L[/tex]
∴ [tex]{1 \ mL=0.001 \ L}[/tex]
The formula to find the concentration will be:
⇒ [tex]Concentration = \frac{moles \ of \ solute \ (mol)}{Volume \ of \ solution \ (L)}[/tex]
On substituting the given values, we get
⇒ [tex]=\frac{18.9\times 10^{-6}}{0.200}[/tex]
⇒ [tex]=9.45\times 10^{-5} \ mol/L[/tex]

Lisa's Chemistry class was performing an experiment with gas pressures. They filled a container with gas at a pressure of 101,000 Pa at room temperature. When they doubled the temperature, the pressure also doubled. What was the new pressure in scientific notation?
Answer:
2.02 × 10^5 Pa
Explanation:
According to this question, in an experiment, a container was filled with gas at pressure of 101,000 Pa, at room temperature. When this temperature was doubled, the pressure also increased by two times i.e.
The pressure changed to (101,000 Pa × 2) = 202,000 Pa
This question is asking to represent this in scientific notation. Scientific notation aims at representing a small or too large number in an easy way. It is done by making use of power of ten i.e. a × 10^b
Where; a = decimal number
b = power of ten
In the case of a large number like 202,000, the power of ten is derived by counting the decimal place backwards. If we are to count until we stop in front of the last digit, we will have 5 times.
That is; 2.02000 × 10^5
We can remove every trailing zeros
Hence, the answer is 2.02 × 10^5 Pa.

Answer:
31 electrons.
Explanation:
Atoms initially have a neutral charge. So if this atom were neutral, it would have 29 electrons to balance out with the 29 protons. Protons are never added or removed. Since this atom has a -2 charge, that means it is an anion with 2 additional electrons. 29e- + 2e- = 31e-

D Volcanic and Sedimentary
Answer:

Explanation:
I took the k12 test and got it right
A continental slope is a boundary between the Continental crust and Oceanic crust. Therefore, option (C) is correct.
What is a continental slope?A continental slope can be described as the slope between the outer edge of the continental shelf and the deep ocean floor. The continental slope is defined as a cut by submarine canyons in many locations and marks the seaward edge of the continental shelf.
Continental slopes follow the boundary between continental and oceanic crust. The Continental slope has a steepness range from 1 to 25 degrees, the average is 4 degrees.
The continental margin lies between the continental shelf and the abyssal plain and comprises a continental slope that is surrounded by the flatter continental rise. It contains thick sediments deposited by currents from the shelf and slope.
The shelf generally ends at a point of increasing slope known as the shelf break and the sea floor under the break is the continental slope.

Answer:

Explanation:
A chemist forms 16.6 g of potassium iodide by combining 3.9 g of potassium with 12.7 g of iodine. Show that these results are consistent with the law of conservation of mass.
The law of conservation of mass states that mass can neither be created nor destroyed by chemical reactions or physical transformations.
The mass of potassium iodide can be calculated from the sum of the mass of potassium and iodine.
The mass of potassium iodide is as follows:-
[tex]Mass\ of \ potassium\ iodide=3.9\ g+12.7\ g\\=16.6\ g[/tex]
So, the total mass of potassium iodide is equal to the mass of potassium plus iodine. So, these results are consistent with the law of conservation of mass.
