Redshift is observed when:(1 point)
A. a luminous object is stationary relative to an observer.
B. a luminous object is traveling alongside an observer.
C. a distant luminous object travels rapidly towards an observer.
D. a distant luminous object travels rapidly away from an observer.
Answers
Answer:it’s C
Explanation:
A distant luminous object travels rapidly away from an observer.
Redshift is observed when a distant luminous object travels rapidly towards an observer. Thus option C is correct.
What is luminous object?Luminous object is defined as the sun is an example of a luminous object, whereas a non-luminous object is one that cannot create light.
It is also defined as objects that can generate their own light energy.
Non luminous object is defined as one that does not generate its own light but can reflect light from other sources.
It can also defined as object which do not generate their own light.
Redshift is defined as when the wavelength of the light is extended, it seems to be shifted towards the red section of the spectrum.
Thus, redshift is observed when a distant luminous object travels rapidly towards an observer. Thus option C is correct.

why the core is metallic and the lower mantle is not.
Answers
Answer:
due to the overlaying layers of strata (layers of earth) an high pressure is created at the core. due to this it behaves like an solid rether than being a liquid... the lower mantle is not solid because in this case the overlaying strata doesn't produce that much pressure on it..

Answers
Answer:
Explanation:
The volume of a balloon is 30 L at 313K and a pressure of 153KPA What is the volume at 273K and 101.3kPa?
from PV=nRT we can derive
PV/T =P'V'/T' so
153X30/313 = 101.3 X V'/273
OR 153 X 30 X273/(313 X 101.3) =V'
V' = 39.5 L

6) Which of the following would travel the farthest in column chromatography?
a. CH3CH2CH2COOH
b. C6H6
c. CH3OH
d. C8H18
Answers
The answer would be C8H18, or octane. Column chromatography is a separation technique that works off of polarity. The stationary phase, in column chromatography, are non-modified silica gels. Silica gels are normally polar. This means the solvent that will elute first are non-polar molecules...then polar molecules. The polar silica gels have a stronger interaction with polar molecules like CH3OH, and therefore will lag the solvent. Additionally, as you decrease the carbons, in hydrocarbons, the molecule becomes more polar. This is not C6H6 isn't the answer and octane is.
C8H18 will travel the farthest in column chromatography.
Chromatography is know as a process of analyzing and purifying organic compounds.There are different forms of chromatography. there is the column chromatography, Gas chromatography etc.
Alkanes are known to be least polar and as such would travel farthest into the mobile phase of the four functional groups. C8H18 belongs to the alkanes family.

Explanation:
Is there a relationship between atomie radius and electronegativity? Why or why not?
Answers
Answer:
Yes
Explanation:
Electronegativity is the tendency for atoms to keep electrons closer to them. So, if the atoms are smaller there, there is a stronger pull on the electrons to keep them closer. So, the larger the atom get, due to electron shielding, it become less electro negative. I hope this help. You might get a better explanation from Khan Academy's video on Electronegativity
Answer:
A relationship is intuitively expected
Does electronegativity relate to atomic radius? A relationship is intuitively expected between electronegativity and radius: the size of an atom is determined by the distribution of electrons around its nucleus. The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.

How does density affect sinking and floating in water?
Answers
Answer:
Density is a measure of how heavy something is compared to its size.
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
Density is a characteristic property of a substance and doesn’t depend on the amount of substance.
Explanation:
If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.
A student might want to know why a boat made out of steel can float when steel is more dense than water. This is not an easy question and requires a different approach than what students have seen so far. We do not necessarily recommend the following explanation for 5th graders but here is the idea:
An object floats when it displaces a volume of water that has a mass equal to the mass of the object. So if a material like steel is shaped into a boat and made larger and larger, it will displace more and more water. When it is large enough to displace a volume of water that has a mass equal to the mass of the boat, the boat will float.

How many moles of ions are there in 1 mole of iron (III) oxide, Fe2O3?
Answers
Answer:
So one mole of Fe2O3 contains two moles of Fe3+ ions.
Explanation:
As there is an internal mole ratio of 2:3
It means that there are 2moles of iron within every mole of iron(III) oxide.
Iron III oxide is an ionic compound composed of Fe3+ ions and O2- ions. According to the formula, there are three O2- ions for every two Fe3+ ions.
Extra:
One 'unit' of Fe2O3 has two Fe3+ ions and three O2- ions, hence a dozen Fe2O3 contains two dozen Fe3+ ions and three dozen O2- ions, and a mole Fe2O3 contains two moles Fe3+ ions and three moles O2- ions.
