The angular resolution of telescope is roughly given by formula:
Where:
λ = wevelength of light
D = diameter of a telescope
First step in solving this question is to convert diameter given in inches into meters:
Telescope A:
6 * 0.0254 = 0.1524m
Telescope B:
10 * 0.0254 = 0.254m
Wavelength of visible light varies from 390nm to 700nm. We will take 500nm as a number for our calculation.
Telescope A:
Telescope B:
The results are given in radians. We need to transform this into degrees.
Telescope A:
Telescope B:
To find out which telescope can distinguish two stars we must convert given angle.
0.7'' is 0.7 arc seconds or 0.7 / 60 / 60 =0.0001944444444444 degrees
Telescope that has angles smaller than this can distinguish. In our case both telescopes have smaller angle and both can distinguish.
Answer:
You would be able to put eight stickers on each folder;
with a remainder of one, the stickers are unable to be divided
equally amongst the six folders.
Step by step:
49/6 = 8.1
Rounded to the nearest whole number:
8
Answer: total books = 8k
Step-by-step explanation:
k = books on each shelf
total books = bookcases * shelves per bookcase * books per shelf (k)
total books = 1 * 8 * k
total books = 8k
D. Plane, because a plane is a side or face of an object.
Let me know if I am incorrect for any reason.
Hope this helps!
