10 points! an energy transformation flow diagram is shown. x is a type of energy and y is the location where the energy transformation is taking place. letter x followed by an arrow with letter y written on top of the arrow and electrical energy written after the arrow what do x and y represent? (4 points) select one: a. x = chemical energy, y = wind turbine b. x = gravitational energy, y = wind turbine c. x = chemical energy, y = thermal power plant d. x = gravitational energy, y = thermal power plant
