Question
Consider two points on the Earth’s surface that are separated by 1 arcsecond as seen from the center of the (assumed to be transparent) Earth. What is the physical distance between the two points?
Expert Solution
Step 1
Given data
- The angular separation between the two points on the earth's surface is given as .
- The radius of the earth is given as r = 6378 km.
The relation between the m to km is given as,
1000 m = 1 km
The relation between the arcsecond to rad is given as,
1 arcsecond = 4.84 x 10-6 rad
