What is sun cost?

Sun cost refers to the amount of sunlight required to plant certain types of plants in the game Plants vs. Zombies. Different plants have different sun costs, which determines how quickly you can plant them during the game.

Is the Sun cooler then Rigel?

No, Rigel is hotter than the Sun. Rigel is a blue supergiant star with a surface temperature that is much hotter than the Sun.

What happens with no sun?

Without the sun, Earth's surface would quickly cool off, leading to extreme and potentially lethal temperatures. Plants would die off due to lack of sunlight for photosynthesis, causing a collapse in the food chain. Ultimately, all life on Earth would struggle to survive without the sun's energy.

What energy you get from the sun?

The energy we receive from the sun is primarily in the form of sunlight, which includes visible light, ultraviolet (UV) light, and infrared radiation. This energy is essential for photosynthesis in plants, warming the Earth's surface, and is harnessed through solar panels to generate electricity.

What is a cme in sun?

A coronal mass ejection (CME) is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space, typically associated with solar flares and solar prominence eruptions. When directed towards Earth, CMEs can cause geomagnetic storms and enhance the auroras.

Which is hotter the explosion of a thermonuclear bomb or the core of the sun and explain why?

The temperatures are similar within about an order of magnitude, but the core of the sun is hotter.

The thermonuclear bomb is at the temperature of DT fusion, the lowest temperature at which fusion can occur. The sun, in addition to fusing DT, is fusing HH, HD, DD, DHe-3, TT, He-3He-3, all of which ignite at various temperatures higher than DT.

How many light years is Eris from the sun?

Eris, the dwarf planet, is roughly 96 astronomical units (AU) away from the sun on average. This is equivalent to approximately 9 billion miles or 15 billion kilometers. In terms of light years, Eris is about 0.001 parsecs away from the sun, or approximately 0.00003 light years.

What is an autorotroph?

An autotroph is an organism that can produce its own food through processes like photosynthesis or chemosynthesis. Autotrophs are able to convert inorganic substances into organic compounds, serving as the foundation of most ecosystems. Examples of autotrophs include plants, algae, and some bacteria.

How are the stars and the sun the same?

Stars and the sun are similar in that they are both luminous celestial bodies made up of gas. The sun is a star, specifically a yellow dwarf star that is the closest to Earth, while other stars are located much further away in the universe. Both stars and the sun emit light and heat through nuclear fusion processes happening in their cores.

What are facts about the corona from the sun?

The corona is the outermost layer of the Sun's atmosphere, extending millions of kilometers into space. It is most easily seen during a total solar eclipse when the bright disk of the Sun is blocked, revealing the fainter corona. The corona is much hotter than the Sun's surface, reaching temperatures of over a million degrees Celsius. It is also the source of the solar wind, a stream of charged particles that constantly flows outward from the Sun.

What is the velocity of sun rays in space?

Light ray comes out in all direction from sun and hence the velocity is ZERO.

You can see the previous answer below and note there it is mentioned SPEED.

Above one is the Answer to the Question

The sun emits many different kinds of rays - visible, ultraviolet, X-ray, infrared, and radio. They all travel at the same speed through a vacuum, such as space: 299,792,458 m/s.

Most people are fine with using a rounded version of the number that is less cumbersome - 300,000,000 m/s, or 3 x 108 m/s.

What is the name of the rings around the sun?

Our sun, Sol, does not have rings around it like planets such as Saturn or Jupiter. However, the halo-like ring of light can be seen extending from it is called the corona.

What surrounds the sun and how far does it extend?

The outermost layer is called the Corona and it extends deep into the Solar System (the Earth is actually within it). Beyond that there is the Sun's magnetic field and of course gravity goes on forever, just getting weaker and weaker.

Is there water vapor on the sun?

yes there is

"So how can there be water molecules on the sun? Well, there are a few cool places, just cool enough that some hydrogen (H) atoms and oxygen atoms (O) can team up to become a water molecule (H2O). Those are the centers of sunspots on the outside of the sun. Sunspots are dark places on the sun with a lot of magnetic field, much much stronger than the earth's magnetic field which pushes your compass needle to the direction of the North pole. In sunspots, the magnetic field is so strong that it pushes the gas largely aside and makes it cool as well. The remaining gas is so cool that there can be a bit of water by H atoms joining O atoms. That is still water vapor, not fluid! You can't go surfing on the sun - and I can't go kayaking there (that's my sport)."

Does sun do combustion?

No, the sun does not undergo combustion. Combustion is a chemical reaction that typically involves oxygen and a fuel source, leading to the release of heat and light. The sun generates energy through nuclear fusion, the process in which hydrogen atoms are fused together to form helium, releasing immense amounts of energy in the form of heat and light.

How can you explain how living things can get energy from the sun directly and indirectly?

Living things can get energy from the sun directly through photosynthesis, where plants and some microorganisms convert sunlight into chemical energy. Indirectly, organisms can obtain sun-derived energy by consuming other organisms that have stored this energy through the food chain. This energy transfer sustains all life on Earth.

What is gravitys affect on Earths revolution around the sun?

Gravity is the force that keeps Earth in orbit around the Sun. The gravitational pull between the two objects causes Earth to move in a curved path around the Sun, creating the elliptical shape of its orbit. Without gravity, Earth would not be able to stay in its orbit and would drift off into space.

What is a non example of the sun?

A nonexample of a sun would have to be the moon.

Why is the sun considered matter but sunlight is not?

The sun is considered matter because it is a massive ball of gas made up of mostly hydrogen and helium that has mass and takes up space. Sunlight, on the other hand, is a form of energy produced by the sun through nuclear fusion reactions in its core. Energy, unlike matter, does not have mass or take up space, so sunlight is not considered matter.

What is a sun in the making called?

the sun is called when in the making is called uaralled star. it means in spanish' good luck' i think!! :D LOL

What are the layers for the sun?

The sun has three main layers: the core, where nuclear fusion occurs; the radiative zone, where energy is transported by electromagnetic radiation; and the convective zone, where energy is transported by convection. The sun's atmosphere includes the photosphere, chromosphere, and corona.

What does convection have to do with the sun?

Convection in the sun is the process by which hot material rises from the sun's core to its surface, cools down, and then sinks back towards the core. This movement of material helps transfer heat to the sun's surface and creates the sun's magnetic field.

Why does the sun only evaporate water?

The sun is a source of heat energy that can cause water to evaporate. The sun's heat provides the necessary energy for water molecules to break free from the liquid state and rise into the atmosphere as water vapor. Other substances can also evaporate under the right conditions, but water is particularly sensitive to the sun's energy due to its molecular structure.

What is the matter emitted by the sun called?

Various things are emitted byt the sun - light and heat are the best known but other electromagnetic waves such as gamma rays are also emitted. Theoretically gravitons are sent out too

Is the sun stronger than water?

In terms of physical strength, water does not have strength like the sun. However, the sun's energy is more powerful and influential in terms of its impact on Earth and its ability to sustain life.
