Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
What else can I help you with?
What is the effect called that shows that some stars are closer than us than others?
It is called the parallex effect.
What is parallex How would you demostrate parallex with your own eyes?
Parallax is the apparent shift in position of an object when viewed from different angles. You can demonstrate parallax with your own eyes by holding your thumb out at arm's length and observing how its position changes when you close one eye and then the other. The background objects will appear to shift relative to your thumb due to parallax.
What is the distance of which an object subtends an angle of parallex equal to one second of arc as viewed from earth?
The distance at which an object subtends an angle of one second of arc, known as a parsec, is approximately 3.26 light years. This unit of measurement is commonly used in astronomy for distances beyond our solar system.

The apparent shift in the position of nearby stars when compared to distant stars is?
called stellar parallax, and it is used to measure the distance to nearby stars. This apparent shift occurs due to the Earth's orbit around the Sun, which causes our viewpoint to change over time. By measuring the angle of the shift, astronomers can calculate the distance to the star.
How can you get an accurate measurement for a population in an area?
Subtract those leaving the area from those in or arriving at the area.
