Question

a geosynchronous satellite is one that stay above the same point on the equator of the earth,so what is the period of such satellite in seconde

Answer 1

A geostationary orbit can be achieved only at an altitude very close to 35,786 kilometres (22,236 miles) and directly above the equator. This equates to an orbital speed of 3.07 kilometres per second (1.91 miles per second) and an orbital period of 1,436 minutes, one sidereal day.

$$T=1436(60)=86160\ s$$
