Question

What is the linear diameter (in meters) of an object that has an angular diameter of 22
arcseconds and a distance of 1,400 m?

Answer 1

Answer: 0.15 m

Step-by-step explanation:

Using the small angle formula

D= kd/206265 where

k= 22 and d= 1400

D= 22 x 1400/206265

D=0.149 m

Hence the linear diameter is 0.15 m.
