Which of the following will allow you to learn something about a transiting planet's atmospheric composition? Which of the follo

wing will allow you to learn something about a transiting planet's atmospheric composition? Compare spectra obtained before and during an eclipse. Use the Doppler method to study the planet throughout a cycle from one transit to the next. Calculate the planet's size, and then use size to infer what its atmospheric composition must be. Look for slight variations in the time between transits.

Answer:

Compare spectra obtained before and during an eclipse

Explanation:

  • The passage of a planet between the star and the earth id called as a transit.
  • The compassion between the spectral variation obtained from the light emitted by the planet can be used to find the presence of the exoplanet.
  • The transiting planet has an atmosphere as some of the light passes from the sun and reaches the earth from the atmosphere of the planet.
  • The brightness goes on decreasing as the planet passes out in an eclipse phase.

Why are sedimentary rocks only found on or close to Earth's surface?
tester [92]

Answer:

Erosion breaks existing rocks and turns them into sediments. The sediments can be formed into rocks by the chemical reactions of dissolved seashells ( Calcium Carbonate.) This reaction can form sediments into rocks very quickly like the formation of concrete ( same chemical reaction). Erosion only happens on the earth's surface.  

As erosion only happens on the earth's surface, sedimentary rocks are only formed on the earth's surface.

In other words:

Sedimentary rocks only found on or close to Earth's surface because sedimentary rocks are made of materials deposited in layers at the Earth's surface.

Law of sines: StartFraction sine (uppercase A) Over a EndFraction = StartFraction sine (uppercase B) Over b EndFraction = StartF
Studentka2010 [4]

Answer:

5.8 units

Explanation:

The sum of angles in a triangle is 180°

<F+35°+65°=180°

<F+100°=180°

<F=180°-100°

<F=80°

Using the sine rule:

\frac{g}{ \sin \: 35}  =  \frac{10}{ \sin \: 80}

We solve for g to get:

g=  \frac{10}{ \sin \: 80}  \times \sin \: 35

g = 5.8

Option A is correct
