Answer: 1) Angular separation equals 0.0000031 degrees
2) Angular separation in arc -seconds equals 0.011156"
Explanation:
For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

Applying values we get

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

2)
The angular separation in arc- seconds is given by

Answer:
Option B.
Explanation:
The mineralogy of previously existing rocks changes, is the right answer.
Chemical weathering is generated by rainwater responding with the mineral fragments in rocks to produce new crystals and water-soluble salts. These reflections transpire expressly when the water is imperceptibly acidic.
These chemical processes require water, and transpire more immediately at higher warmth, so hot, humid atmospheres are best. Chemical weathering (particularly oxidation and hydrolysis) is the initial stage in the creation of soils. During chemical weathering, the mineralogy of previously existing rocks changes.
