A slow change to the earth's surface would be the formation of mountain ranges over millions of years due to the shifting of tectonic plates under the earth. Also, another slow change could be considered erosion or weathering. Two rapid changes could be landslides and earthquakes.
Answer:
Option (C)
Explanation:
The angular resolution formula,
Sin A= 0.25 (Wavelength ÷ Diameter)
where, wavelength is taken in micrometer and diameter is in meter.
Here, wavelength (W)= 650 nm = 0.65 μm (converting nanometer into micrometer)
Diameter= 2 m
now, according to the formula,
![\sin A=0.25\times [\dfrac{wavelength}{diameter}]\\\\\sin A=0.25\times \dfrac{0.65\ \mu m}{2\ m}\\\\\sin A=0.08125''\\\\\sin A\approx 0.082''](https://tex.z-dn.net/?f=%5Csin%20A%3D0.25%5Ctimes%20%5B%5Cdfrac%7Bwavelength%7D%7Bdiameter%7D%5D%5C%5C%5C%5C%5Csin%20A%3D0.25%5Ctimes%20%5Cdfrac%7B0.65%5C%20%5Cmu%20m%7D%7B2%5C%20m%7D%5C%5C%5C%5C%5Csin%20A%3D0.08125%27%27%5C%5C%5C%5C%5Csin%20A%5Capprox%200.082%27%27)
Thus, the correct answer is option (C) i.e. 0.082 arc second.
