Assignment Help Science
Reference no: EM131126927

The physical diameter of an object can be calculated if the angular diameter and distance are known. The relationship is:

diameter = 2*pi*d*a/360,

where d = distance; a = angular diameter.

Suppose we have an object whose angular diameter is 2 degrees at a distance of 1000 km. What is its real diameter?
