Answer:
angular diameter is 1382.04 arcseconds
Step-by-step explanation:
given data
diameter d = 5 meters
distance D = 3 km = 3000 meter
to find out
angular diameter
solution
we know that angular diameter ( θ ) formula that is diameter / distance
θ = d/D
put here both value to get angular diameter
and we know 1 rad = 360/2π and 1 degree = 60 (arcminutes) and 1 (arcminutes) = 60 (arcseconds)
so
angular diameter = 5 / 3000
angular diameter = 0.00666 radian
angular diameter = 0.0067 × 57.3 = 0.383
angular diameter = 0.3839 × 3600
angular diameter = 0.3839 × 3600
angular diameter is 1382.04
