Which circuit hook-up design will have the brightest light bulb?A - 1 battery 1 bulb, B - 2 batteries 1 bulb, C - 3 batteries one bulb, D 2 batteries the bulb is on the other end, E 1 battery and 1 bulb on the other end
Question 5 options:
A
B
C
D
E
Heres another for you guys!
Answers
Answer:
I believe it is E because the battery has a wire, a power source(the battery), and a bulb connected together thus making a full series circuit. Furthermore, the more batteries they are to a series circuit, the more dimmer the light bulbs will be.

Yet again earth science
Answers
Answer:
Engery is the driving force of the oxygen cycle is photosynthesis itself, which is responsible for the creation and maintenance of earth's atmosphere.Plants are able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen.
Answer:
Energy is the main force of the oxygen cycle and not to mention also photosynthesis, which is responsible for the creation of the earth's atmosphere. This would also mean that plants are the main focus of the Oxygen cycle and energy is needed to make plants. So without energy, no plants would exist! Not to mention the oxygen cycle wouldn't work without energy. Plants are also able to use the energy of sunlight to convert carbon dioxide and water into carbohydrates and oxygen.

Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
for example 4.5×10⁻³
In standard notation
4.5 / 10³
0.0045
The expanded notation is standard notation of writing the numerical values which is normal way. The numbers are written as they are, without the power of 10.

what are some similarities between polar and nonpolar molecules
Answers
Answer:
Explanation:
Polar bonds also often contribute to a net dipole moment of a molecule. This basically means that there are partial charges that make a molecule overall polar. One example might be water: in H20, oxygen is very electronegative, and hydrogen is less so. This means that oxygen is more negative and hydrogen is more positive. This is why water is cohesive (can stick together): The positive ends stick to the negative ends.
To solve this we must be knowing each and every concept related to polar molecule. Therefore, polar and nonpolar molecules are covalent compound.
What is polar molecule?A polar molecule is a type of chemical compound where there is an uneven distribution of electrons among the covalently bound atoms.
The term "polarity" refers to how unlike two molecules' electrical poles are from one another. If they are quite dissimilar, the species is said to be an extremely polar molecule.
Because of the more symmetrical distribution of the electrons, non-polar molecules do not have a lot of charges on their opposing sides. The fees are all offset by one another. Polar and nonpolar molecules are covalent compound.
Therefore, polar and nonpolar molecules are covalent compound.

Most of the carbon in the rocks that form Earth's mantle and crust was stored there when Earth formed. The rest of Earth's carbon is stored and exchanged in many ways.In a model of the carbon cycle, which process does NOT contribute directly to the storage of carbon within sediment?
Answers
Answer:
Photosynthesis.
Explanation:
In photosynthesis process, carbondioxide gas enters into plant leaves from which plant produces organic molecules such as glucose. This glucose helps the plant to increase it growth and complete development stages and finally the plant dies and buried in the soil so due to decomposition process, the carbon present in the plant body releases in the soil and become part of sediments. So indirectly photosynthesis process provides carbon to the soil.

Explanation:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
The equation above is not balanced. It can be balance as illustrated below:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 at the right side. It can be balance by 6 in front of CO₂ as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on right side. It can be balance by 5 in front of H₂O as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O
There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by 6 in front of O₂ as illustrated below:

Answer : The correct option is, electron.
Explanation :
As we know that,
An atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or the center of the nucleus where the mass of the an atom is concentrated.
The electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
According to the question, the electron subatomic particle found revolving around the nucleus.
Hence, the correct option is electron.

The burning of a sample of propane generated 1 04.6 kJ of heat. All of this heat was used to heat 500.0 g of water that had an initial temperature of 20.0/C. What was the final temperature of the water?
Answers
Answer: 70.0°C
Explanation:
Quantity of heat = Mass * Specific heat * Change in temperature
Quantity of heat = 104.6 KJ
Mass = 500.0 g
Specific heat of water is 4.18 J/g°C
Change in temperature assuming final temperature is x = x - 20
Units should be in grams and joules:
104,600 = 500 * 4.18 * (x - 20)
104,600 = 2,090 * (x - 20)
x - 20 = 104,600/2,090
x = 104,600/2,090 + 20
x = 69.8
= 70.0°C

What is polymerization reaction?High-molecular-weight compounds known as polymers are created by the aggregation of several smaller molecules known as monomers. Polymers make up the natural and manmade fibres used in clothes as well as the polymers that have revolutionised society.
Two fundamental methods for creating polymers exist: (a) joining small molecules together by an addition reaction, and (b) joining molecules while getting rid of a stable small molecule like water. Condensation processes, which combine addition and elimination reactions, are what this later type of polymerization is known as. H-O* + CH[tex]_3[/tex]-CH[tex]_3[/tex] → H-O-CH[tex]_2[/tex]-CH[tex]_2[/tex]* is an example of an initiation phase for an addition polymerization reaction.
