HELLLPPP MEEEEE PLSSSS BRANLIEST ANSWER WILL BE AWAREDED Prepare a report on how is solar energy used in scientific experiments.
Answer:
SOLAR ENERGY
Our primary source of clean, abundant energy is the sun. The sun deposits 120,000 TW of
radiation on the surface of the Earth, far exceeding human needs even in the most aggressive
energy demand scenarios. The sun is Earth’s natural power source, driving the circulation of
global wind and ocean currents, the cycle of water evaporation and condensation that creates
rivers and lakes, and the biological cycles of photosynthesis and life. Covering 0.16% of the land
on Earth with 10% efficient solar conversion systems would provide 20 TW of power, nearly
twice the world’s consumption rate of fossil energy and the equivalent 20,000 1-GWe nuclear
fission plants. These comparisons illustrate the impressive magnitude of the solar resource,
providing an energy stream far more potent than present-day human technology can achieve.
All routes for utilizing solar energy exploit the functional steps of capture, conversion, and
storage. The sun’s energy arrives on Earth as radiation distributed across the color spectrum
from infrared to ultraviolet. The energy of this radiation must be captured as excited electronhole pairs in a semiconductor, a dye, or a chromophore, or as heat in a thermal storage medium.
Excited electrons and holes can be tapped off for immediate conversion to electrical power, or
transferred to biological or chemical molecules for conversion to fuel. Natural photosynthesis
produces fuel in the form of sugars and other carbohydrates derived from the reduction of CO2 in
the atmosphere and used to power the growth of plants. The plants themselves become available as biomass for combustion as primary fuels or for conversion in reactors to secondary fuels like
liquid ethanol or gaseous carbon monoxide, methane, and hydrogen. We are now learning to
mimic the natural photosynthetic process in the laboratory using artificial molecular assemblies,
where the excited electrons and holes can drive chemical reactions to produce fuels that link to
our existing energy networks. Atmospheric CO2 can be reduced to ethanol or methane, or water
can be split to create hydrogen. These fuels are the storage media for solar energy, bridging the
natural day-night, winter-summer, and cloudy-sunny cycles of solar radiation.
In addition to electric and chemical conversion routes, solar radiation can be converted to heat
energy. Solar concentrators focus sunlight collected over a large area to a line or spot where heat
is collected in an absorber. Temperatures as high as 3,000°C can be generated to drive chemical
reactions, or heat can be collected at lower temperatures and transferred to a thermal storage
medium like water for distributed space heating or steam to drive an engine. Effective storage of
solar energy as heat requires developing thermal storage media that accumulate heat efficiently
during sunny periods and release heat slowly during dark or cloudy periods. Heat is one of the
most versatile forms of energy, the common link in nearly all our energy networks. Solar thermal
conversion can replace much of the heat now supplied by fossil fuel.
Although many routes use solar energy to produce electricity, fuel, and heat, none are currently
competitive with fossil fuels for a combination of cost, reliability, and performance. Solar
electricity from photovoltaics is too costly, by factors of 5–10, to compete with fossil-derived
electricity, and is too costly by factors of 25–50 to compete with fossil fuel as a primary energy
source. Solar fuels in the form of biomass produce electricity and heat at costs that are within
range of fossil fuels, but their production capacity is limited. The low efficiency with which they
convert sunlight to stored energy means large land areas are required. To produce the full 13 TW
of power used by the planet, nearly all the arable land on Earth would need to be planted with
switchgrass, the fastest-growing energy crop. Artificial photosynthetic systems are promising
routes for converting solar energy to fuels, but they are still in the laboratory stage where the
principles of their assembly and functionality are being explored. Solar thermal systems provide
the lowest-cost solar electricity at the present time, but require large areas in the Sun Belt and
breakthroughs in materials to become economically competitive with fossil energy as a primary
energy source. While solar energy has enormous promise as a clean, abundant, economical
energy source, it presents formidable basic research challenges in designing materials and in
understanding the electronic and molecular basis of capture, conversion, and storage before its
promise can be realized.

Choose the fact from the statements below. a. Everyone should start eating kale. b. My auntie makes the most delicious pancakes. c. The sun set over the mountains. d. His tuxedo was a little too fancy for the party.
Answer:
c. The sun set over the mountains.
Explanation:
A fact is information about something which is seen or proven to be true. It cannot be a whimsical expression or something that one wishes, but more of a known occurrence. A fact is the opposite of fiction.
Among the given statements, the only statement that is a fact is sentence c. The setting of the sun over the mountains is a known fact and also has occurred and is still occurring, with many people who have seen and enjoyed it.
On the other hand, the other statements are based on a personal expression about something or the other.
Thus, the correct answer is option c.

This is an essay I had to write for an exam, I tried to make it as long as I could using one of those generators to fit the standards, it was difficult. can someone revise it for me and tell me if there's anything wrong with it?
It was a breezy yet warm midsummer day on July twenty-fifth 2012, and I essentially was more than yare to relish my summer with my friends. Ash, my (now non binary) friend, was going to be having a birthday beach party at the shores approximately 3 hours away that day. I particularly was genuinely exhilarated in a pretty big way.
I had to get ready within two hours, take a shower, fine-tune my hair, brush my teeth, get one of my bathing suits, and ascertain I had a good amount of sunscreen on. I'm jumbling attempting to get things done as quickly as possible afore we depart from our house, apparel on the floor scattered like broken glass, which is quite significant to what was about to happen.
I'm running like lightning, then, I tripped on some shoes laying around Flat on my face, hard enough to cause the ground to crack. My mother rushes in to visually perceive if I'm okay, and what all the noise was about. She optically canvassed my face, and her ocular perceivers widened, horrified as if she visually perceived a ghost.
I particularly asked her what was erroneous, and she optically canvassed me shocked, I conscientiously brushed the sort of blonde hair out of my face as she still for all intents and purposes had the horrified look on hers. I kind of abstracted my hand from my mouth to later optically actually discern blood on my fingers. I licked around my mouth to for all intents and purposes feel an immensely colossal gap where my fairly canine teeth used to be a minute ago and particularly felt a sharp pain in my gums in a subtle, yet excruciating way.
body
My mom verbalizes, "Oh honey, you lost your baby teeth!" she exclaimed, but I wasn't as happy as she was, I had a party to generally go to in twenty minutes in a fairly major way, and my gums were gushing blood! I didn't want my friends to visually perceive my missing teeth and laugh at me, which is fairly significant. So, I obnubilated in my room and told my mom I didn't wish to go at all anymore. She reassured me, kindly telling me that's BS, and verbally expressed they'd celebrate I'm delicately comely, particularly contrary to my personal belief.
I didn't believe her at first, but, after a couple of minutes of optically canvassing my reflection as my mother ran to find her car keys, I mostly commenced to celebrate. Maybe it wasn't so deplorable, sort of contrary to my past belief. We then went to the dentists, to then get the leftover broken teeth removed from my gums. After a couple of hours, we decided to go despite my missing teeth, and the fact we were super late.
conclusion
mum for the most part was right, contrary to my personal belief. Most everyone didn't care. The next day, I got ridiculed intensely, but marginally. It wasn't proximately as deplorable as I mentally conceived it would be, or so they thought. I now actually like my teeth.

PL HELP!!!!!!!!!!!!!!!
[1]Nothing that comes from the desert expresses its extremes better than the unhappy growth of the
tree yuccas. Tormented, thin forests of it stalk drearily in the high mesas, particularly in that
triangular slip that fans out eastward from the meeting of the Sierras and coastwise hills. The
yucca bristles with bayonet-pointed leaves, dull green, growing shaggy with age like an old
[5] man's tangled gray beard, tipped with panicles of foul, greenish blooms. After its death, which is
slow, the ghostly hollow network of its woody skeleton, with hardly power to rot, makes even
the moonlight fearful. But it isnÕt always this way. Before the yucca has come to flower, while
yet its bloom is a luxurious, creamy, cone-shaped bud of the size of a small cabbage, full of
sugary sap, the Indians twist it deftly out of its fence of daggers and roast the prize for their
[10] own delectation.
Why does the author use the words "bayonet-pointed" (line 4) and "fence of daggers" (line 9) to describe the leaves of the yucca tree?
To create an image of the sharp edges of the plant
To emphasize how beautiful the plant's leaves are
To explain when and where the plant grows
To show how afraid the author is of the plant
Answer:
To communicate how rare it is to find the bloom.

. When the speaker of "War Is Kind" says, "Do not weep, maiden, for war is kind," what technique is he using to make his point? F Exaggeration G Situational irony H Rhythm and rhyme J Verbal irony
Answer:
J. Verbal Irony
Explanation:
War is Kind is a poem by Steven Crane.
The poem begins with the speaker telling a maiden not to weep -
Do not weep, maiden, for war is kind
The technique used here is verbal irony.
Verbal Irony: This is a literary technique that occurs when a speaker says something that contrasts with what he means; his actions and emotions.
Verbal irony was used on the line above.
The speaker is very much aware of the brutality and unkind nature of war but still describes war as a kind phenomenon and tells the maiden not to weep.

the rainy day:
The day is cold, and dark, and dreary
It rains, and the wind is never weary;
The vine still clings to the mouldering wall,
But at every gust the dead leaves fall,
And the day is dark and dreary.
My life is cold, and dark, and dreary;
It rains, and the wind is never weary;
My thoughts still cling to the mouldering Past,
But the hopes of youth fall thick in the blast,
And the days are dark and dreary.
Be still, sad heart! and cease repining;
Behind the clouds is the sun still shining;
Thy fate is the common fate of all,
Into each life some rain must fall,
Some days must be dark and dreary

We real cool. We
Left school. We
Lurk late. We
Strike straight. We

Explanation:
Jensen walked into the crime scene, under the police tape, to face a crowded group of police crowded around a solitary body on the ground, with 3 distinct gun shots in the shape of a triangle around her heart. The victim was identified as Natalie Stack man, a 24 year old from New York City. She had a pale complexion with fair hair and perfectly shaped red lips. There was no sign of any marks on her body to indicate a struggle; she was placed in a perfect position on the ground, her hands resting perfectly on her stomach, as if the murderer had placed her in that position on purpose. Members of the CSI team had estimated her time of death to be around 2am that same day. It was time they caught this killer before he struck again.
Jensen kicked with all his might as the door which flew open. All three of his man stood at the door faced with two men, bearing snipers. The men knew they didn’t stand a chance and lowered their guns. Jensen quickly located Kevin and quickly walked up to him and handcuffed him.
Jensen took Kevin back to the station where he confessed to everything. Kevin wanted revenge on Natalie, he wanted his money back, so he followed her back to her apartment.

Today was the day of my big dance performance! I had been
practicing
for weeks and I had the whole dance memorized. When I got to the
performance hall, I put on my new shoes and hat. I checked my
reflection in the mirror. "I look good!" I thought with a grin. It was
almost my turn to perform, so I peeked out from behind the curtain.
There were so many people in the audience! I began to feel a little
nervous. But then I saw my parents smiling in the front row. "I can do
this!" I thought to myself. When the curtain opened and the music
started, I felt my confidence grow as I remembered all the steps I had
practiced.
First, I heard the beat get fast, so I did a quick spin and tipped my hat.
When the beat slowed down, I did a shuffle and twist. I was almost
finished dancing, when suddenly, I saw that there was a loose board
at the front of the stage. But it was too late, I tripped over it and
almost fell off stage! I caught myself just in time and jumped
backward, pretending like it was just part of my dance. The music
ended and I bowed. Everyone in the audience jumped to their feet and
clapped. My parents were cheering loudest of all. I was so happy that I
did a little jig and smiled before walking off stage. After the
performance was over, my coach gave me a pat on the back and said,
"Nice job, Marcus!” My parents were so proud of me, they took me to
get ice cream!
