Hey mate....
Explanation:
This is ur answer....
By adjusting the path length while observing the interference pattern and carefully measuring the change in path length, the wavelength of the light (λ) can be determined. The speed of light is then calculated using the equation c = λf.

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.

write and balance sodium when it burns in air to form sodium peroxide
Answers
Answer:7.229 grams of oxygen is formed by the complete reaction of 35.23 g of metallic sodium with oxygen at 130–200 °C, a process that generates sodium oxide, which in a separate stage absorbs oxygen: 4 Na + O2 → 2 Na2O. The ozone oxidizes the sodium to form sodium peroxide.

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.

NO2 is a reddish brown color while N2O4 is colorless. Based on this information only, which type of spectroscopy would be a good choice to determine the identity of an unknown sample that contains either
NO2 or N2O4?
Answers
Spectroscopy is is an area of science that deals with interaction of matter and the electromagnetic spectrum. Colorimetry can distinguish between a colorless and a colored substance.
The type of spectroscopy that would be a good choice to determine the identity of an unknown sample is a type of spectroscopy that deal with the interaction of visible light with matter.
A type of spectroscopy that deals with interaction of visible light with matter is colorimetry. Colorimetry can measure the concentration of a substance as a function of the amount of light that is absorbed by the substance.
Since NO2 has a reddish brown color, its concentration can be measured using colorimetry. The concentration of N2O4 can not be measured using colorimetry because it is colorless.
