A proposed space station includes living quarters in a circular ring 51.0 m in diameter. At what angular speed should the ring rotate so the occupants feel that they have the same weight as they do on Earth?

0.620 rad/s

Explanation:

Given that:

diameter of the ring = 51.0 m

radius = diameter/2 = 51.0 m/2

= 25.5 m

In the system, the centripetal force is equal to the force as a result of the weight;

∴

mω²r = mg

ω²r = g

where:

ω = angular speed

ω = 0.620 rad/s

It is false that during exercise, the oxygen concentration in the blood increases to twice that of resting levels. As a matter of fact, the oxygen either stays the same or decreases, or it may increase slightly than it used to be when the person was resting, but it definitely does not double while exercising. Hope this helps. Let me know if you need additional help!
