A circular space station (shaped like a big wheel) rotates to produce "artificial gravity". The apparent weight of an astronaut standing on the inside surface of the outer wall is equal to her weight on earth. The inside surface of the outer wall of the space station is 285 m from the axis of rotation. What is the period of rotation of the station?
A) 92 s
B) 34 s
C) 213 s
D) 183 s

The centripetal acceleration required for artificial gravity is equal to g (9.8 m/s²). Using the formula for centripetal acceleration a = (4π²r)/T², where r = 285 m, solving for T gives approximately 34 seconds.
