To support the claim that the kinetic energy of an object is transferred to a different form of energy in the context of a hydroelectric dam, the following three statements apply:
1. **D**: The motion of a spinning turbine generates electricity, transforming energy from one form to another.
- This statement illustrates how the kinetic energy of moving water is converted into electrical energy through the turbine.
2. **E**: The motion of falling water moving through the dam turns a turbine, transferring energy from the water to the turbine.
- This statement describes the process where the kinetic energy of falling water is transferred to the turbine, emphasizing the transfer of energy.
3. **B**: The motion of falling water makes a sound, which is another form of energy.
- This statement highlights how the kinetic energy of falling water can be transformed into sound energy, which is another form of energy.
