<span>Fluorine is a chemical element with symbol F and atomic number 9. It is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. As the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine</span>

As a distant star moves away from earth, the light given off by the star has a
Troyanec [42]

Answer:

The wavelength of these photons will become longer. The energy of each of these photons will become lower.

Explanation:

<h3>Wavelength</h3>

Light can be considered as electromagnetic waves. The wavelength of a wave is equal to the minimum distance between two troughs (lowest points) in this wave. On the other hand, the frequency of a wave is equal to the number of wavelengths that this wave travels in unit time.

Assume that the speed of light stays the same. The distance that this beam of light travels in unit time will be the same. However, with a lower frequency, there would be fewer wavelengths in that same distance. Therefore, the size of each wavelength will become longer.

If c represent the speed of light and f represents the frequency, then the wavelength would be:

\displaystyle \lambda = \frac{c}{f}.

<h3>Energy</h3>

The energy E of each proton of a beam of light is proportional to the frequency f of the light. Let h denote Planck's Constant. The numerical relation between E\! and f\! would be:

E = h\, f.

Therefore, if the frequency f of this light becomes smaller, the energy E of each of its proton will also become proportionally lower.

Can you please help me with the green question
solmaris [256]
I was flung towards the atmosphere. Slowly but surely, I made my way inside. On my way there, I began to heat up. I began to vibrate rapidly, and I noted it happened as I entered the atmosphere. I think it was because we sped up so much, but I can't say for sure because I'm an air particle... However, I do know that I am now a heated air particle due to friction and movement from entering the atmosphere. I think I'll cool down on my descent, I don't know that I can get much hotter than this.

A student analyzed an antacid tablet from a bottle containing 120 tablets purchased for $2.79. The mass of the tablet was 1.247
BaLLatris [955]

The cost of one antacid is 2.325 cents per tablet.

<u>Explanation:</u>

As per the question based on the student analysis we know that,

Total antacid tablets in a bottle = 120

Purchase Price of a bottle = $ 2.79

Cost of 1 antacid tablet =\frac{2.79}{120}  

As we know $1 = 100 cent

The cost of 1 antacid tablet = \frac{2.79}{120} × 100 cents = 2.325 cents/tablet .

Thus we came to know that it costs 2.325 cents/tablet .
