The development of renewable resources has the goal of reducing greenhouse gasses in the atmosphere.
In the last decades there has been increased effects on the climate and atmosphere on our planet, and it is obvious that the reason for that are the human activities and the usage of fossil fuels and coal. Because of this people have started to develop and invest more and more into the renewable resources, thus step by step replacing the fossil fuels and coal, and protect the environment.
Many of the people living in the south pacific islands lack the needed education and live in poverty. The technology is not so advanced there either.
The corona the outer layer of Sun is not visible during day time because bright sun. We can not see stars during day time. This is because during the normal daytime, the photosphere's bright light outshines the corona, like it does the chromosphere, but telescopes specially designed to take photographs of the inner corona, calledcoronagraphs, can block out the light of the photosphere and help astronomers study its properties a bit.
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.
<span>The Standard English language is British Received Pronunciation (BRP). It came from London, Cambridge, and Oxford. It spread through hierarchical diffusion in the upper-class of English society. Grammar books and dictionaries were printed using Received Pronunciation in 1476 when the printing press was introduced. these books quickly diffused throughout </span>Britain.
