What happens if you use a salted egg instead of a hard-boiled egg?Answer: C. It will spin like a hard boiled egg.The salt in a salted egg doesn't significantly alter the egg's overall density or mass distribution compared to a hard-boiled egg. Therefore, both will exhibit similar spinning behavior due to their comparable centers of gravity.What happens if you use a balloon filled with water?Answer: A. It will spin like a fresh egg.A water balloon, like a fresh egg, contains a liquid interior that shifts during rotation, causing it to wobble and stop spinning quickly unlike a solid hard-boiled egg. This shifting center of gravity prevents sustained spinning, mirroring the behavior of a fresh egg.
