Which transformation must occur when a dam uses water to generate energy? A. Mechanical energy to potential energy
B. Chemical energy to potential energy
C. Mechanical energy to electrical energy
D. Chemical energy to electrical energy
Whats the correct Answer??​

Which transformation must occur when a dam uses water to generate energy A Mechanical energy to potential energy B Chemical energy to potential energyC Mechanic class=

Respuesta :

I would say C.

Dams don't use any chemical means to get their energy output, so B and D are out. A converts to potential energy which can't produce electricity without being set in motion, so it doesn't work. That leaves B, which makes sense. Potential energy to mechanical energy to electrical energy.
