Here are the following speeches:
<span>Speaker A: It was a combination of the Protestant</span>wind and the island nature of our nationthat protected us. Surely, Philip must beupset at his defeat.
<span><span>Speaker B: </span>Our archipelago and divine winds have</span>protected us once again. The Mongolsmay have taken China, but they cannotconquer us.
<span><span>Speaker C: </span>To support our growing population, we</span>must find a suitable way to farm. Withfloating gardens on our lake, we shouldbe able to grow enough to meet ourdemand.
<span><span>Speaker D: </span>We have connected highland and lowland</span>areas by building networks of roads andbridges. We have also built terraces intoour mountainsides to grow crops
Answer:
it can be developing because such nation has many processes in progress
The answer to this is C. 5.
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.
