Explanation:
Did you know that the night sky is an illusion?
Stars are so far away that it takes millions or billions of years for the light to shine on the Earth. This means that when we see the stars, the 'stars' we are seeing aren't actually there anymore. They have moved but since the light took so long to get to Earth, the stars aren't there. Scientists think that if we put a giant mirror 20 thousand light-years from earth and looked into it, we would be able to see the dinosaurs. This proves that time travel is possible and we just don't have the technology yet.

what systems help us taking a test ?
Answers
Answer:
The nervous system. The human body uses the nervous system to think, process and send messages and feelings throughout our body. We wouldn't be able to taste, smell, hear, think, write, or move without it. That's what helps us put clues together and send them to our brains figuring out the possible outcome of something or especially for test taking.

Answers
Answer:
A glance at the night sky above Earth shows that some stars are much brighter than others. However, the brightness of a star depends on its composition and how far it is from the planet.
Astronomers define star brightness in terms of apparent magnitude — how bright the star appears from Earth — and absolute magnitude — how bright the star appears at a standard distance of 32.6 light-years, or 10 parsecs. (A light-year is the distance light travels in one year — about 6 trillion miles, or 10 trillion kilometers.) Astronomers also measure luminosity — the amount of energy (light) that a star emits from its surface.
Measuring star brightness is an ancient idea, but today astronomers use more precise tools to obtain the calculation. Specifically, they use the electromagnetic spectrum, focusing on the wavelengths visible to the human eyes. Every star has a distinctive spectrum of light, which to our eyes is rendered as a color.

Can some one help? And also explain it? The question is how titan in Saturn evaporated I’m just confused by this question I just don’t know what to write as a response…. Help?!?
Answers
The process of how Titan's atmosphere evaporated is an interesting one. Titan is the largest moon of Saturn and has a thick atmosphere primarily composed of nitrogen, similar to Earth's atmosphere. The evaporation of Titan's atmosphere is related to its surface temperature, atmospheric pressure, and the composition of its atmosphere.
Here's a simplified explanation of how Titan's atmosphere can evaporate:
1. Surface Temperature: Titan is a very cold moon with surface temperatures averaging around -290 degrees Fahrenheit (-179 degrees Celsius). At such low temperatures, some of the gases in the atmosphere, like methane and ethane, exist in liquid form on the surface.
2. Atmospheric Pressure: Despite being cold, Titan's atmosphere is relatively dense, with a surface pressure about 50% higher than Earth's. This atmospheric pressure helps keep the gases in the atmosphere from escaping into space easily.
3. Evaporation: Even at such low temperatures, some of the liquid hydrocarbons on Titan's surface can evaporate and become gases in the atmosphere. This process is similar to how water evaporates from Earth's oceans and lakes, despite not reaching boiling temperatures.
4. Condensation: Conversely, when the gases in Titan's atmosphere lose energy, they can condense and return to the surface as liquid. This is similar to how water vapor in Earth's atmosphere condenses to form clouds and eventually falls as rain.
Overall, the balance between evaporation and condensation in Titan's atmosphere is influenced by its temperature, atmospheric pressure, and the composition of its atmosphere. The low temperatures and high atmospheric pressure allow for the existence of liquid hydrocarbons on the surface and their occasional evaporation into the atmosphere.
I hope this explanation helps you understand how Titan's atmosphere can evaporate despite being a cold moon. If you have any further questions or need more clarification, feel free to ask!

D) longer wavelength.
Answers
Answer: D) longer wavelength.
Explanation:
As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

Answers
Answer:Melting.
Freezing.
Evaporation.
Condensation.
Sublimation.
Explanation:
Answer: Examples for the five transformations previously given.
For the first four, we encounter common examples in everyday life, all to do with water:
Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.
Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.
Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.
Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer
While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.
Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

is (H2O) water a compound of a element? is Ozone a compound of a element? explain. please help me!!
Answers
Answer:
H20 is a compound and ozone is a compound to because the got more then u elements in it
Explanation:
Answer:
Water is a compound because it is composed from two hydrogen atom and one oxygen atom. Water is considered a compound because it is made up of more than one element. By definition, a compound is composed of multiple atoms from different elements. Water has 2 hydrogens and 1 oxygen.
A compound is a combination of more than one element.
A molecule is the smallest particle of an element or a compound.
Oxygen(O) is an element.
O2 - is a molecule which is formed by making a double bond with another Oxygen.
O3 - is a molecule as well, which comprises of three oxygens with two single bonds and one double bond. The resonance structure has a partial positive charge on the central Oxygen and partial negative charges on the end oxygens.
Explanation:
"In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds."

Explanation:
Took quiz and got it right
A pink roses are formed when red roses are mated with white roses shows incomplete dominance.
What is incomplete dominance?Incomplete dominance is defined as the dominance occurs from a cross in which each parental contribution is genetically distinct and produces children with an intermediate phenotype.
Semi-dominance and partial dominance are other terms for incomplete dominance.
Genes with the alleles IA, IB, and I are responsible for expression of A, B, and O blood types shows multiple alleles.
A red flower and a white flower produce an offspring with equal proportions of red and white coloration shows codominance.
Thus, a pink roses are formed when red roses are mated with white roses shows incomplete dominance.
