← ScienceWhich risk increases when an elevator's cable snaps in freefall?
A)Occupant inertia causes destructive compaction.✓
B)Air resistance induces terminal velocity.
C)Gravitational potential creates weightlessness.
D)Electromagnetic brakes restore power.
💡 Explanation
Occupant inertia causes destructive compaction because occupants continue downward with their original velocity according to Newton's first law. This impact force depends on deceleration and mass, therefore rapid deceleration amplifies injury risk rather than air resistance reducing it.
