Fill in the blanks in the statements about parallax. As the distance to an object decreases, the observed parallax . A parsec is defined as the distance to an object when the is equal to one arcsecond. When the parallax is 0.1 arcseconds , the distance is .

As the distance to an object decreases, the observed parallax _Increases_ . A parsec is defined as the distance to an object when the _Angle_ is equal to one arcsecond. When the parallax is 0.1 arcseconds , the distance is _10 parsecs_.

Explanation:

A Parallax in astronomy is the apparent displacement of an object because of a change in the observer's point of view. This is use to measure distances to nearby stars. As the distance to a star increases, the its parallax decreases and vice-versa.

Parallax formula can be express as:

d=1/p

Where:

p = parallax angle in arcseconds

d = distance in Parsecs

Parallax Second = Parsec (pc)

A star with a parallax of 1 arcsecond has a distance of 1 Parsec.

Given:

p = 0.1 arcseconds

from:

d=1/p

d=1/0.1 arcseconds

d=10 parsecs
