which one of these are not used to power generators?

A- wind
B- moving water
C- hot rocks under earth's surface
D- static electricity

The answer is C.

I mean B. but what's your answer that you picked?

Thnx and I picked C

okay, yeah that's what I was agreeing with. either C or B but it would certainly be c.

To determine which option is not used to power generators, we need to understand the sources of electricity generation commonly used.

A- Wind: Wind turbines generate electricity by harnessing the kinetic energy of wind. This option is used to power generators.

B- Moving water: Hydroelectric power plants generate electricity by converting the potential energy of moving water into electrical energy. This option is also used to power generators.

C- Hot rocks under the earth's surface: Geothermal power plants generate electricity by tapping into the natural heat beneath the Earth's surface. This heat is used to produce steam, which then drives turbines to generate electricity. Therefore, this option is used to power generators.

D- Static electricity: Static electricity is different from the other options mentioned above. It is typically created through an imbalance of electric charges, such as when we rub certain materials together. However, converting static electricity into usable electrical energy on a large scale is not currently a widely used method for powering generators. Therefore, the option "D- static electricity" is the correct answer.
