Science

The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

What attracts many horseflies to be in your home?

Horseflies are attracted to the warmth and carbon dioxide emitted by humans. They may enter homes through open doors or windows in search of a blood meal. They can also be attracted to sources of food or trash within the home.

How long does it take for corn to grow in dark places?

Corn cannot grow in complete darkness as it requires sunlight for photosynthesis, which is essential for its growth. Without sunlight, the corn plant will not be able to produce the energy it needs to grow.

What are the different types of zuchinni?

There are several types of zucchini, including green zucchini (most common), yellow zucchini (also known as summer squash), round zucchini (also known as globe zucchini), and striped zucchini (such as the Costata Romanesco variety). Each type varies slightly in shape, color, and size but can generally be used interchangeably in recipes.

What things reflect light in the dark?

Objects that reflect light in the dark include mirrors, reflective surfaces like glass or water, metallic objects, and materials with a high level of phosphorescence or luminescence. These surfaces bounce light back towards the source, making them visible in the dark.

What are the effects of treated wastewater?

Unfortunately, you did not specify the effects on WHAT? The environment? Human health? Irrigation?

Anyhow, wastewater is often treated with disinfectants (e.g. chlorine) in order to kill any stressed or otherwise living bio-contaminants such as pathogenic e. coli and cysts. The by-product of disinfection can be Tetrahalomethanes, or THM's which are carcinogenic. They form when organic matter reacts with the disinfectant. As far as the environment, wastewater can cause eutrophication in waterbodies, which can lead to algal blooms and low dissolved oxygen content. On the positive sie, those excessive nutrients can also support a larger biotic community, though undesirable to people. Wastewater is often used to irrigate places like parks, golf-courses, and agriculture, which saves ground water resources. As far as consumption, it is not advisable to consume wastewater, since cysts and other biocontaminants CAN and DO survive the disinfection process. They can hide within "biofilms" that sometimes go unpenetrated by disinfectants. Ozone is an effective disinfectant that leaves no harmful byproduct in the water, but it is seldom used because it is more expensive.

What would happen to surface temperatures on your planet if the Suns energy were absorbed and NOT re-radiated?

The planet's life would not exist and reach temperatures nearing absolute zero.

No, that answer is completely incorrect. The question asks what would happen if all of the sun's incoming radiation was absorbed, and none of it was re-radiated back into space.

The answer is that the Earth would heat up. The atmosphere would get hotter too, and more and more of it would escape into space until very little remained. By now the oceans would be hot enough to steam, and then to boil. Once the oceans had all boiled dry, and the atmosphere escaped into space, what would be left would be a hot, dry planet that got hotter and hotter as it absorbed solar energy. Eventually some of the metals with lower melting points would begin to melt and form pools - of tin and zinc, for example. As time went on, more and more metals would melt out of the rocks. In the end, the crust of the Earth would become molten.

Early in this process life would be wiped out.

The earth would stay heated up because of the greenhouse effect.

Artificial sources of light?

Artificial sources of light include incandescent bulbs, fluorescent tubes, LED lights, and halogen lamps. These sources produce light through electricity or gas, and are commonly used for indoor and outdoor lighting. Artificial light helps illuminate spaces and provide visibility during nighttime or in dark environments.

What pen is used in Space?

A Fisher Space Pen, specifically the AG7 model, is commonly used in space by astronauts due to its ability to write in microgravity, extreme temperatures, and upside down. The pen uses a specially formulated ink that is pressurized to work in the harsh conditions of space.

How big is 100 solar masses?

100 solar masses is equivalent to the mass of 100 times our Sun. In terms of exact numerical value, the mass of the Sun is approximately 2 x 10^30 kg. So, 100 solar masses would be around 2 x 10^32 kg.

Can someone give me ideas for a science fair project using 3d glasses?

You could explore the effects of different colored lenses in 3D glasses on perceived depth perception. Another idea is to investigate how the distance between the two lenses in 3D glasses affects the clarity of the 3D effect. Finally, you could look into how varying the angle at which 3D glasses are worn impacts the viewer's experience of the 3D images.

When and where was the hottest time in Alaska?

the warmest place in Alaska is the southern most point and the warmest time is summer and spring when the sun comes up. during winter and fall it remains dark and sunless

What would be the least authoritative source for a science project about the solar system?

Personal blogs or social media posts from individuals without expertise in space or astronomy would be the least authoritative sources for a science project about the solar system. It is essential to rely on credible scientific sources such as NASA or academic journal articles to ensure accuracy and reliability of the information presented in the project.

Can gamma rays travel through empty space?

Yes, gamma rays can travel through empty space because they are a form of electromagnetic radiation like light. They are the most energetic form of electromagnetic radiation and can pass through most materials, including empty space, due to their high penetrating power.

Is a Bunsen burner adjusted by turning the collar?

Yes, the flame on a Bunsen burner can be adjusted by turning the collar, which controls the amount of air that mixes with the gas before it combusts. Turning the collar can change the size and intensity of the flame produced by the Bunsen burner.

What is a small meteroid that burns up Earth's atmosphere?

A small meteoroid that burns up in Earth's atmosphere is called a meteor. As it enters the Earth's atmosphere, the friction with the air causes it to heat up and glow, creating a streak of light known as a "shooting star."

What field of science that studies sea animals?

Marine biology is the field of science that studies sea animals, including their behavior, physiology, interactions with their environment, and how they adapt to life in the ocean.

How have rockets developed and changed over time?

Rockets have evolved from early gunpowder-driven devices in ancient China to modern liquid-fueled rockets used in space exploration. Advances in technology have led to more efficient propulsion systems, improved materials, and greater precision in navigation and control. Today, rockets are used for various applications including space missions, satellite launches, and commercial aerospace ventures.

Are there living things in outer space aside from earth?

As of now, there is no confirmed evidence of living things in outer space aside from Earth. Scientists continue to explore space for signs of extraterrestrial life, such as microbial organisms on other planets or moons.

How is metric system converted to english?

It depends what units you are making. for example: 1ft=12in. for better usage use a calculator and a measuring tape.

Not only that, if the unit you want to convert is either bigger or smaller than the output number depending on what it is you have to multiply or divide.

What are the factor that effects the brightness of a star?

Luminosity, size and distance. If all distances were equal, larger and hotter stars would be the brightest. But a so-so star 40 light years away, will frequently be brighter than a brilliant star 40,000 light years away, etc.

A is an organism that absorbs food from the surface it lives on?

A is likely a type of fungus or plant that obtains nutrients through osmosis or absorption from its environment. It may not possess the ability to actively seek out food sources but relies on what is available in its immediate surroundings.

What is a solar system object that enters Earth's atmosphere and becomes very hot due to friction between the object and Earth's atmosphere?

A meteoroid is a small rocky or metallic body in outer space. When it enters Earth's atmosphere, it is known as a meteor and starts to burn up due to friction, creating a bright streak of light in the sky. If a meteor survives the journey through the atmosphere and lands on Earth's surface, it is called a meteorite.

When during the day should you look for your shadow?

You should look for your shadow when the sun is shining at its peak, around midday. This is when the sun is highest in the sky, causing your shadow to be the shortest.

What is the line through the middle of a quasar?

A quasar is a lot like a black hole, in that it was once a star. There are many spikes that do project from the center of the quasar. These are optical spikes. they are like a glare that the telescopes see when they look at a star. if you look at the sun off of a mirror, you can see the same optical spikes from the sun. It is basically a You can also see another line that extends from both sides of the quasar. These lines that you see are actually super heated gas that has been shot out from the center of the quasar. These streams extend many light-years away from the quasar. If you want to learn more, look at some of the Hubble pictures of quasars.
