Answers
Answer : The chemical equation for the beta decay process of \(_{11}^{24}\textrm{Na}\) follows:
\(_{11}^{24}\textrm{Na}\rightarrow _{12}^{24}\textrm{Mg}+_{-1}^0\beta\)
Explanation :
Beta decay : It is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.
The released beta particle is also known as electron.

Answers
Answer: Explanation:
Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

In the game of billiards, all the balls have approximately the same mass, about 0.17 kg. In the figure, the cue ball strikes another ball such that it follows the path shown. The other ball has a speed of 1.5 m/s immediately after the collision. What is the speed (in m/s) of the cue ball after the collision?
Answers
Answer:
v = 2.6 m/s
Explanation:
The question is incomplete because the diagram is not given in the question.
The diagram of this question is attached below.
According to the law of conversation of momentum.
mv(initial) = mv(final)
We can see in the diagram that:
mv(initial) = 3 × 0.17
mv(final) = mv₁(final) + mv₂(final)
Consider only the horizontal components of velocities, to compare them to initial velocity.
mv(final) = mv₁(final) + mv₂(final)
0.17 × 3 = (0.17)(v)(cos 30) + (0.17)(1.5)(cos 60)
0.51 = 0.1472v + 0.1275
0.3825 = 0.1472v
v = 2.6 m/s

Amelia makes a Venn diagram to compare the advantages and disadvantages of asexual reproduction and sexual reproduction.
Which label belongs in the region marked X?
Less competition for resources
Faster
No variation in DNA
Less energy required
Answers
This is because asexual reproduction results in offspring that are genetically identical to the parent, so there is no variation in their DNA. The other options listed - less competition for resources, faster, and less energy required - are all advantages of asexual reproduction and would not belong in the region marked X, which typically represents a disadvantage of the process being compared.

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.
Pls, mark as brainlist
NO MEAT OR BREAD type foods- artificial/processed/attracts animals. Even buying a compost off amazon is a great idea because most human trash every year can be composted. Hope this helps :)
Keep some moister in it and make sure it gets sun. If bugs get in it, not a big deal. As well, if stuff rots, it’s ok that’s normal.
Discuss one component of your school's recycling system that could be automated and predict the economic impact.
Answers
One component of my school's recycling system that could be automated is the sorting of recyclables. Currently, the school relies on students and staff to sort recyclables into the appropriate bins, which can be time-consuming and may result in contamination if materials are not sorted properly.
Automating the sorting process with a machine or conveyor belt system could improve the efficiency and accuracy of the recycling system. It could also potentially reduce labor costs associated with manual sorting.
The economic impact of automating the sorting process would depend on the initial cost of the equipment and any associated installation or maintenance costs. However, over time, the improved efficiency and accuracy of the system could result in cost savings for the school. Additionally, the increased efficiency of the system could potentially lead to increased recycling rates, which could result in cost savings for waste disposal and potentially generate revenue through the sale of recycled materials.
Answer:
Our school has color coded virtual trash cans. For example, a trash can for only paper will only accept paper items, if the item put inside is not paper, it will litter it out and all students have cleaning duties throughout the week so even if you or someone litters you’ll probably have to clean it up at some point anyways. I honestly think it’s very cool. (i wish this was true smh).
