Explanation / Answer
1.B Mechanical
Water rushes past the turbine hitting it's blades and causing it to spin converting some of the waters kinetic energy into mechanical energy the water then finally flows out of the dam and continuous its journey downstream.A shaft connects the turbine generator when the turbines spins so does the generator.The generator uses an Electromagnetic field to convert this mechanical energy into electrical energy
2.A Hydroelectricity
Hydroelectric energy is potential energy that is converted to kinetic energy through the forces of gravitation,which again comes from solar energy ,driving the water cycle around.hydroelectric energy is the result of heat energy from the sun and the gravitational force from the earth.
