Astar is located 12.5 parsecs away from us. what is its parallax angle? d = 1/p

Explanation:

In the image attached you can observe where is the parallax angle placed.

Now, this parallax angle is inversely proportional to the distance measured in parsecs. That means, the greater the distance, the smaller the parallax angle.

Mathematically, it's defined as

Where , replacing this value, we have

Therefore, the parallax angle is 0.08 seconds of arc.

spare some change and give it to the poor

explanation:

plz : ((

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
