A diver in a swimming pool bends his head before diving. It

Answer»

INCREASES his linear velocity
decreases his ANGULAR velocity
increases his moments of inertia
decreases his moment of inertia

Solution :When a DIVER bends his head, radius of gyration R decreases.
Moment of inertia `I=MR^(2)`
Since R decreases, moment of inertia ALSO decreases.
