Question

question 11 (1 point)
which of the following energy sources obtains its energy from gravitational potential energy?
○ wind generator
○ a coal - burning power plant
○ a geothermal power plant
○ a hydroelectric power plant
question 12 (1 point)
what is the source of geothermal energy?
○ radioactive decay
○ fossil fuel combustion
○ nuclear fussion
○ nuclear fission

Explanation:

1. Hydroelectric power plants store water at elevated heights, converting the stored gravitational potential energy of the water into kinetic energy, then electrical energy.
2. Geothermal energy originates from the radioactive decay of elements within Earth's core and mantle, which generates the heat that is harnessed for this energy source.

Answer:

1. a hydroelectric power plant
2. radioactive decay
