Question

A geostationary (Clarke-band) satellite at Albany's longitude will

  a

always be visible from Albany
  b

never be visible from Albany
  c

sometimes be visible from Albany

 

Expert Solution
Check Mark
Step 1

Geostationary satellite has a time period of rotation equal to 24 hours if the circular orbit is on the equatorial plane of the earth, then the satellite will appear stationary at a point on the equatorial region of the earth.

As Albany is situated on that region so the satellite at Albany's longitude will always visible. 

Heights for geostationary satellite will be given by - h

RE+h = (T2GME/4π2)1/3
