When most main sequence stars exhaust their hydrogen supply, they become giants. Yet on the diagram, there are not many stars between the main sequence and the giants. What would explain this fact?

Awheel rotates without friction about a stationary horizontal axis at the center of the wheel. a constant tangential force equal to 82.0 n is applied to the rim of the wheel. the wheel has radius 0.150 m . starting from rest, the wheel has an angular speed of 12.8 rev/s after 3.88 s. what is the moment of inertia of the wheel?
