what purpose whould sand serve to water? (right answers only i will give brainliest!)
Answer:
If you pour water on the sand, the water seems to disappear into the sand. ... This happens because under pressure the sand grains actually push each other slightly farther apart, which makes more space between them. This means there is more space for water to flow into, resulting in a dry footprint on the beach.

Discuss one component of your school's recycling system that could be automated and predict the economic impact.
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 need to explain the electromagnetic spectrum to fifth graders.
Answer:
Explanation:
The electromagnetic spectrum is the range of frequencies (the spectrum) of electromagnetic radiation and their respective wavelengths and photon energies.
The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. There is no known limit for long and short wavelengths. Extreme ultraviolet, soft X-rays, hard X-rays and gamma rays are classified as ionizing radiation because their photons have enough energy to ionize atoms, causing chemical reactions. Exposure to ionizing radiation can be a health hazard, causing radiation sickness, DNA damage and cancer. Radiation of visible light and longer wavelengths are classified as nonionizing radiation because they have insufficient energy to cause these effects.
Throughout most of the electromagnetic spectrum, spectroscopy can be used to separate waves of different frequencies, producing a spectrum of the constituent frequencies. Spectroscopy is used to study the interactions of electromagnetic waves with matter.[4]

Would a moon much smaller than our moon exert a gravitational pull on objects, too? How about something
the size of a mountain? Or a building? A car? An apple? Describe the effect that mass has on the gravitational
pull of an object.
Answer:
The gravitational force exerted is same the only difference arises because of the masses of earth and moon since the mass of earth is quite large as compared to Moon so effect on Earth is quite insignificant as compared to effect on moon.
Explanation:
Answer:
The Moon's surface gravity is about 1/6th as powerful or about 1.6 meters per second. The Moon's surface gravity is weaker because it is far less massive than Earth.

Which of the following forces has not changed Earth's surface?
folding
erosion
weathering
gravity
Answer:Gravity is the force among the options listed that has not directly changed Earth's surface.
Explanation:
Gravity is a fundamental force that acts on all objects with mass, including the Earth itself, but it does not cause changes or modifications to the Earth's surface features. Instead, gravity influences the movement of materials and the shape of the Earth's surface by exerting a pulling force on objects. On the other hand, folding, erosion, and weathering are all processes that directly contribute to shaping

C. A solution of silver nitrate is added to a solution of sodium chloride. A solid white substance forms.
D. A solution of sodium sulfide is added to hydroiodic acid. A rotten smell is given off.
Answer:
A. Large chunks of sodium chloride are placed in a mortar and pestle. The sodium chloride is broken into smaller pieces.
Explanation:
This is an example of physical change where the physical properties of the substance are altered without any formation of a new substance. So, it is not an evidence of a chemical reaction.
A student is shown a picture of a large number of stars clumped together without a discernible shape. The student argues that these stars cannot be a galaxy because all galaxies have familiar shapes such as barred, elliptical, and spiral. Is the student correct?
A.
Yes. These stars cannot be a galaxy if they do not form a familiar shape.
B.
The stars cannot be a galaxy, but the student incorrectly lists "barred" as a possible shape. All galaxies are either elliptical, spiral, or spheroidal.
C.
Although all galaxies have familiar shapes, no single image can capture an entire galaxy. If the student could see the entire galaxy, it would have a familiar shape.
D.
No. The stars could be part of an irregular galaxy.
Answer:
D.
Explanation:
Irregular galaxies have no identifiable shape or structure to them. They are often chaotic in appearance, without a bulge or any trace of spiral arms.
A student shows a picture of many large stars clumped together without a discernible shape. So the stars could be a part of an irregular galaxy. Hence, option D is correct.
What is a Galaxy?All galaxies are collections of stars and other celestial bodies that are gravitationally bound. The cosmos contains more than 100 billion galaxies, each of which has stunning formations visible in photographs captured by telescopes of the far universe.
According to Jenna Samuel, a doctoral candidate in astrophysics at the University of California, Davis, a galaxy can be conceptualized as a collection of stars, gas, and dark matter that are all gravitationally bonded to one another. "What we imagine as a normal galaxy is largely the light section — the stars — that's embedded in a much larger dark matter halo, which spreads much further out," the researcher explained.

Please help: The average depth of water in a place near the coast of th Pacific ocean is 5.om. The largest tidal range in that place is 2.0m. Calculate the maximum depth of water at that place. please do not attempt to steal points... thank you <3!
Answer:
The maximum depth of the water at the place is 6.0 meters.
Given the tidal range and average depth, it is to be noted that the maximum depth of the water at the place, is 6.0 meters.
How can you calculate Maximum Depth using Average Depth and Tidal Range?The tidal range is the successive difference between tide highs and lows, which is a sinusoidal pattern. On the basis of the above, it is correct to state that the tidal range is twice of the amplitude of the tide level.
That is:
The Amplitude of the tide, A = 2.0/2m = 1m
The maximum depth at the place, therefore, is given as:
D\(_{max}\) = A + D\(_{ave}\)
Hence,
D\(_{max}\) = 1.0 + 5.0 = 6.0
Thus, it is correct to state that the Maximum Depth (D\(_{max}\)) = 6.0 Meters.
