Explain how your battery works. (You may want to look at the Electric Current lesson) What are some possible materials you could use to make your battery?
Answers
Answer:
Batteries have the positive end Cathode, and a negative end of anode. There is also an electrolyte that allows electrical charges to go from the cathode to the anode.
-Anode most often is made of zinc
- Manganese dioxide as Cathode.
- the electrolyte contains ions
Explanation:
GIVE THE OTHER DUDE BRAINLIEST
A battery is made up of three parts. The Cathode (positive end +), the Anode (negative end -), and the electrolyte.
What is the battery?Batteries have a negative end called the anode and a positive end called the cathode. Another electrolyte facilitates the transfer of electrical charges from the cathode to the anode.
Between the cathode and anode, electrical charges can move thanks to the electrolyte. The flow of electricity that results from these chemical reactions provides the electrical voltage potential needed to power a circuit.
The following list includes typical battery materials.
- Zinc is typically used to make anodes.
- The cathode is manganese dioxide.
- There are ions in the electrolyte inside and between.
Therefore, three components make up a battery. The electrolyte, the cathode (positive end +), and the anode (negative end -).

What would happen to the digestion process if enzymes were not present
Answers
Answer: It would take 2.3 billion years for the biological reaction without the presence of enzymes. It’s because, without them, your body can’t break down foods so that nutrients can be fully absorbed. Every organ, every tissue, and every 100 trillion cells in our body rely upon the reaction of metabolic enzymes and their energy component.
Explanation:
I hope this helps
Without enzymes, the body would not be able to break down complex carbohydrates, proteins, and fats into their component molecules. This means that these nutrients would not be absorbed by the body and would be excreted as waste.
Additionally, the lack of enzymes would make it difficult for the body to digest and absorb vitamins and minerals. This could lead to malnutrition and other health problems over time.
Overall, the absence of enzymes from the digestive process would severely impair the body's ability to extract nutrients from food and could have negative consequences for overall health and well-being.

What fraction of the Moon model was always lit up by the light in your model?
Answers
Answer:10
Explanation:
In the context of the Moon model, the fraction of the Moon that was always lit up by the light is half, or 1/2.
The explanation for this is that the Moon model discussed previously most likely depicts the Moon's phases as seen from Earth. The phases of the moon are caused by distinct areas of the lit side of the moon that are visible from Earth at various times during its orbit.
The Sun always illuminates half of the Moon's surface, leaving the other side in darkness. From Earth, we can only see the bright portion; the unlit portion is invisible. Different phases result from variations in the visible fraction of the lighted half of the Moon as it revolves around the Earth.
Therefore, the fraction of the Moon that was always lit up by the light is half, or 1/2.

1.What is a non example of constant?
2.What is an example of constant?
Answers
Answer:
1. A non example of a constant in physics is a value that changes. For example, the temperature of Hong Kong, let's say, is not a constant, since it changes and does not stay at the same value. It gets higher in the summer and lower in the winter.
2. An example of a constant in physics would be the gravitational acceleration of the Earth. Since the Earth's mass' changes is negligible when compared with the overall mass of the Earth (unless something big happens, of course, like a meteor or asteroid), the gravitational acceleration on Earth is largely unchanged, even constant from our viewpoint.
Explanation:
Hope this helped!
Answer:
a science experiment, the controlled or constant variable is a variable that does not change. For example, in an experiment to test the effect of different lights on plants, other factors that affect plant growth and health, such as soil quality and watering, would need to remain constant. a dependant variable(opposite)would be the properties of the plants themselves, which the scientist is observing in relation to the changing light. These properties might include the plants' color, height and general health of the plant

Answers
Answer:
Explanation: COMPOST BIN
WHAT IS A COMPOST BIN?
A compost bin is a container into which you place organic waste to turn into compost (organic material) over time.
Most compost bins are designed to hasten the decomposition of organic matter through proper aeration and moisture retention. With the proper combination of air and moisture, ideal conditions are produced for the activity of aerobic organisms responsible for the high temperatures that transform the organic materials into compost
Read on to find out how to start a compost bin, DIY compost bin ideas, and more tips for beginners.
The decomposition process will eventually take place over time in a compost "pile" or "heap," even without any housing to contain the matter. However, a compost bin is worth it because it helps speed up decomposition and keeps the area neat. Some bins are continuous, meaning you can keep adding waste to them, while others create batches of compost with a set mix of ingredients you add all at once. Depending on the style of compost bin you choose, bins can also have the advantage of making it harder for rats to get at your compost. This is true of the tumbler type, for example.
CHOOSING THE RIGHT BIN
Select the right bin for your composting needs. You can make an inexpensive compost container out of almost any container or material. Some ideas include:
Plastic storage container
Plastic bucket
Trash cans
Straw bales
Lumber
Branches harvested from the woods
Stone
Cinder blocks
Wire fencing
Ceramic (also popular for a kitchen countertop compost bin)
The best bin, however, is one you can easily turn or rotate consistently to control odors and make sure all the materials decompose. This is especially important for aerobic composting (more information below). A tumbler composting bin is pricey, but you can DIY one from barrels and sawhorses. You can turn compost with a rake or shovel in a non-rotating bin, it just takes more labor to do so.

List three evidences that show that the Bible is the Word of God.
Answers
Answer:1.God tells us that He is the Author (2 Peter 1:20-21 Open in Logos Bible Software (if available) & 2 Timothy 3:15-17 Open in Logos Bible Software (if available))
1.The Old Testament and New Testament Authors understood they were writing the Word of God. Common Old Testament phrase – “Thus saith the Lord”. The Apostle Peter confirmed the Apostle Paul’s writings as Scripture (2 Peter 3:16)
3.Its Historical Accuracy – as verified by archeology, which has never contradicted the Bible, but only confirms and silences its critics.
Explanation:
Answer:
Many people question who the author of the Bible is and wonder if the Bible is really the Word of God. I want to give you five reasons to affirm that the Bible is God's Word.
The Word of God: Evidence that Scripture is Divine
First, I believe the Bible is the Word of God because of its scientific accuracy. The Truth of the Word of God tells us that God “hangeth the earth upon nothing” (Job 26:7). How did Job know that the earth hung in space before the age of modern astronomy and space travel? The Holy Spirit told him. The scientists of Isaiah’s day didn’t know the topography of the earth, but Isaiah said, “It is [God] that sitteth upon the circle of the earth” (Isaiah 40:22). The word for “circle” here means a globe or sphere. How did Isaiah know that God says upon the circle of the earth? By divine inspiration.
Secondly, the Bible is affirmed through historical accuracy. Do you remember the story about the handwriting on the wall that is found in the fifth chapter of Daniel? Belshazzar hosted a feast with a thousand of his lords and ladies. Suddenly, a gruesome hand appeared out of nowhere and began to write on a wall. The king was disturbed and asked for someone to interpret the writing. Daniel was found and gave the interpretation. After the interpretation, “Then commanded Belshazzar, and they clothed Daniel with scarlet, and put a chain of gold about his neck, and made a proclamation concerning him, that he should be the third ruler in the kingdom.” (Daniel 5:29). Basing their opinion on Babylonian records, the historians claim this never happened. According to the records, the last king of Babylon was not Belshazzar, but a man named Nabonidas. And so, they said, the Bible is in error. There wasn’t a record of a king named Belshazzar. Well, the spades of archeologists continued to do their work. In 1853, an inscription was found on a cornerstone of a temple built by Nabonidas, to the god Ur, which read: “May I, Nabonidas, king of Babylon, not sin against thee. And may reverence for thee dwell in the heart of Belshazzar, my first-born favorite son.” From other inscriptions, it was learned that Belshazzar and Nabonidas were co-regents. Nabonidas traveled while Belshazzar stayed home to run the kingdom. Now that we know that Belshazzar and Nabonidas were co-regents, it makes sense that Belshazzar would say that Daniel would be the third ruler. What a marvelous nugget of truth tucked away in the Word of God!

A balanced chemical equation reflects the idea that the mass of the products. A.is greater than the mass of the reactants. B.is less than the mass of the reactants. C.equals the mass of the reactants. D.is not related to the mass of the reactants.
Answers
Answer:
My answer to the question is option C.
A balanced chemical equation reflects the idea that the mass of the products is equal to the mass of the reactants. The correct option is C.
In a balanced chemical equation, the mass of the products must be equal to the mass of the reactants.
According to the law of conservation of mass, in a chemical reaction, the mass of the products must be equal to the mass of the reactants because matter cannot be created or destroyed, it only can be transformed.
For example, for the given reaction:
CH₄ + 2O₂ → CO₂ + 2H₂O
The mass of the reaction is:
\( m_{CH_{4}} + m_{O_{2}} = m_{CO_{2}} + m_{H_{2}O} \)
So the sum of the masses of the reactants must be equal to the sum of the masses of the products.
Therefore, the correct option is C.
