Answer:
(a). The orbital speed of this space station is 7906.42 m/s.
(b). The period of the space station is 5062.2 sec.
Step-by-step explanation:
Given that,
Gravitational constant

Mass of earth

Radius of earth

(a). We need to calculate the orbital speed of this space station
Using formula of orbital speed



(b). We need to calculate the period of the space station
Using formula of period

Put the value into the formula


Hence, (a). The orbital speed of this space station is 7906.42 m/s.
(b). The period of the space station is 5062.2 sec.
