0.01 arc second is one hundredth of an arc-second.
An arc-second is one sixtieth of an arc-minute. (There are about 30 arc-seconds across the visible diameter of the Sun or Moon).
An arc-minute is one sixtieth of a degree.
A degree is one three hundred and sixtieth of a circle.
So a hundredth of an arc-second is a good resolution for a fine telescope.
If you have an image of the Moon where the moon is 3000 pixels wide (probably twice the width of your computer screen) then 0.01 arc-second is one pixel.

What are the two words that when put together derive the term parsec?
A parsec is a distance corresponding to a parallax of one arcsecond. The two words that form "parsec" are parallax and arcsecond.
Two stars having annual parallax of 0.1 and 0.02 arc seconds respectively.If they appear to have same magnitude. estimate the actual distance of these stars from us?
The 'parsec' (3.26 light years) is the distance at which an object exhibits an annual parallax of 1 arcsecond. Although the whole idea is based in the trigonometric tangent of angles, we can assume a perfectly linear relationship for such small angles. -- 0.1 arcsecond ==> 3.26/0.1 = 32.6 light years -- 0.02 arcsecond ==> 3.26/0.02 = 163 light years Their magnitude has nothing to do with the question you asked. It may be relevant to the second part of the question from which you copied only the first part. Thanks for including all of the given data, though.
What is the diameter of a star if its angular diameter is 0.044 arcsecond and its distance is 427 light-years?
The diameter of the star would be 197.07 times the suns diameter, 1.83 astronomical units, about 170 million miles or 270 million kilometres.

An angle of 1 arcsecond is?
1 degree = 60 minutes1 minute = 60 secondsThus, a degree has 3600 seconds.1 degree = 60 minutes1 minute = 60 secondsThus, a degree has 3600 seconds.1 degree = 60 minutes1 minute = 60 secondsThus, a degree has 3600 seconds.1 degree = 60 minutes1 minute = 60 secondsThus, a degree has 3600 seconds.
