Question

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 0.2 arcseconds, the distance is answer bank 5 parsecs 0.2 parsecs parsecs parallax 5 au decreases increases

Explanation:

1. Parallax is inversely proportional to distance. So, as distance decreases, parallax increases.
2. A parsec is defined based on parallax. When the parallax is one arc - second, the distance is one parsec.
3. The relationship between distance $d$ (in parsecs) and parallax $p$ (in arc - seconds) is $d=\frac{1}{p}$. When $p = 0.2$ arc - seconds, $d=\frac{1}{0.2}=5$ parsecs.

Answer:

1. increases
2. parallax
3. 5 parsecs
