Wind moves because air above land is cooler than the air above water.
There are lot of different pollutants that are putting the well being of the Earth's spheres in danger. These pollutants come mostly from the human activities. It may look as a simple solution to just through all the pollutants in the ocean and dissolve them in it, but it doesn't work that way. If something like this is done, it will cause an ecological disaster. The pollutants will change the composition of the water, with lot of toxic chemicals included, which will result in mass extinction of the marine organisms. The change of the water composition will also lead to changes in its properties and behavior, so it will affect the ocean currents, as well as the climate patterns around the globe.
Atmosphere because there is only 4 spheres biosphere, hydrosphere, and geosphere which have nothing to do with space
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.
