D. control rods are
I hope dis helps :3
Brakers are to a car as control rods are to a nuclear-fission chain reaction. The correct option is D.
What is a nuclear-fission chain?A chain reaction occurs when neutrons generated during fission cause subsequent fission in at least one more nucleus.
This nucleus creates neutrons, and the cycle continues.
The process can be either controlled (nuclear power) or uncontrolled (nuclear weapons) (nuclear weapons).
Thus, the correct option is D. control rods are.

Answer:
A. like poles of magnets repel each other
B. Unlike poles of magnets attract each other.
C. The magnet's force is stronger than the earth's at this distance
Explanation:
From the diagram given, we can take the portion of the compass painted red to be the north, and the porion painted white to be the south.
In the first diagram, the north of the compass gets attracted to the south of the compass showing, that unlike poles attract each other and like poles repel each other.
In the second diagram, the south of the compass needle gets attracted to the north of the magnet showing, that like poles repel each other, and unlike poles attract each other.
The mere fact that the compass needle is not pointing towards the north shows that it is being affected by the magnet placed beside it. Normally every compass held under the influence of the magnetic pull of the earth points north. But since this is not the case here, we can say that The magnet's force is stronger than the earth's at this distance

Drag the slider from January to December. Based on what you observe, do you think Barcelona has large temperature changes throughout the year?
Answers
Answer:
Yes.
Explanation:
Yes, I think that Barcelona has large temperature changes throughout the year because Barcelona has minimum temperature of 33°F in winter season and maximum temperature of 88°F in summer season. In Barcelona, the summers are short, warm, and humid while on the other hand, the winters in Barcelona are long, cold, and partly cloudy. The temperature typically varies from 40°F to 83°F and is rarely goes below 33°F or above 88°F.

Answer & Explanation: Acid rain occurs when sulfur dioxide and nitrogen oxide are released into the air to create a chemical reaction. When the two mix in the air (oxygen), they will get into the water and mix with other pollutants in the air, making acid rain.
Answer:
What is acid rain? Acid rain occurs when sulfur dioxide and nitrogen oxide are released into the air to create a chemical reaction. When the two mix in the air (oxygen), they will get into the water and mix with other pollutants in the air, making acid rain.
What causes acid rain the most? It can be caused by useing nonrenewable resources. Which inclues coal, oil, ect.
What effects can acid rain have? It causes respiratory issues in animals and humans. When acid rain falls down and flows into the rivers and ponds it affects the aquatic ecosystem. It alters the chemical composition of the water, to a form which is actually harmful to the aquatic ecosystem to survive and causes water pollution which can harm our fresh water supply.

Chemical A breaks down into chemical B. At t=0, [A] = 0.100 M. At t=10.0 s, [A] = 0.075 M. What is
the average reaction rate?
Beach
Answers
Answer:
a0.075 i think so average number
To solve this we need to have knowledge of average reaction rate which relates the rate to the change in concentration to the change in time. The average rate of reaction is 0.0025.
What is rate law?A rate law represents the rate of a reaction . According to this rate is directly proportional to the concentration of reactants. There is another expression of rate law which is integrated rate law which is just opposite of differential rate law.
The average rate law for given reaction is given as:
Rate =Change in concentration÷ change in time
Change in concentration=Final concentration - initial concentration
= 0.075 M-0.100 M
=0.025
Change in time =10.0-0=10.0
substituting the values
Rate =0.025÷ 10.0
Rate =0.025÷ 10.0=0.0025
Therefore, the average rate of reaction is 0.0025.

if the lightbulb receives 100 J of electrical energy, and gives off 75 energy, how much heat (thermal energy away from the lightbulb?
Answers
Answer:
Amount of heat energy released by light bulb = 25 joules
Explanation:
Given:
Energy receive by light bulb = 100 Joules
Energy released by light bulb as light energy = 75 Joules
Find:
Amount of heat energy released by light bulb
Computation:
We know that, energy is neither be created nor destroys
So,
Using Law of conservation of energy
Energy receive by light bulb = Energy released by light bulb as light energy + Amount of heat energy released by light bulb
100 = 75 + Amount of heat energy released by light bulb
Amount of heat energy released by light bulb = 100 - 75
Amount of heat energy released by light bulb = 25 joules

Answers
Answer:
Explanation:
The chemical formula of nitrogen is N2
A mol of Nitrogen atoms = 14 grams
So N2 will have a molar mass of 14 * 2 = 28 grams
number of moles of N2 = given mass / molar mass
number of moles of N2 = 12 / 28
number of moles of N2 = 0.4286 mols
