← ScienceWhich outcome demonstrates the equivalence principle for a freefalling elevator?
A)Weight vanishes inside the elevator✓
B)Internal clocks accelerate rapidly
C)Earth's magnetic field intensifies
D)Elevator temperature decreases steadily
💡 Explanation
The equivalence principle predicts weightlessness because gravitational acceleration is indistinguishable from inertial acceleration within the frame. Therefore, objects float rather than clocks accelerating, stemming from magnetic or thermal causes under normal earth conditions.
