Answer:The objects in order from least to greatest potential energy:
3<1<4<2
Explanation:
1. Potential energy of a 15-kilogram stone found at a height of 3 meters:
2. Potential energy 10 kilograms of water stored at a height of 9 meters:
3. Potential energy 1-kilogram ball located 20 meters in the air:
4. Potential energy box of books weighing 25 kilograms placed on a shelf 2 meters high:
The objects in order from least to greatest potential energy:
3<1<4<2
