the period of revolution of the space station is 25.1 seconds.
Calculation :
acceleration ac=v2/r
velocity v=(2*pi*r)/T
therefore T2 = (4*pi²*r)/ac
= (4*pi²*40)/2.5
given, diameter = 80m therefore radius r=40m
= 25.1 seconds
A space station is a spacecraft capable of supporting a human crew in orbit for long periods of time, and is therefore a kind of living space in space. No greater propulsion or landing system. An orbital station or orbital space station is a satellite (that is, a type of orbital spaceflight). A station needs a docking port so that other spacecraft can dock to transfer crew and supplies. The purpose of maintaining an orbital outpost varies by program. The space station was launched primarily for scientific purposes, but military launches have also taken place.
