PLEASE HELP! I WILL MARK BRAINLIEST AND I REALLY NEED HELP PLEASE! DUE BY THE END OF TODAY THIS IS SCIENCE JSYK

8.) What is necessary to transform the chemical energy in fossil fuels into the electricity that our cell phones, computers, air conditioners, and refrigerators use? (1 point)

9.) Number the events of the example of hydropower electricity generation from 1 (the start) to 5 (the finish). Read the list once or twice before you attempt to sequence it. (5 points)

As water moves down the waterfall, the water’s potential energy from its earlier position transforms into motion/kinetic energy.

The electricity travels through wires from the generator in the hydro-station to your house, and the wires continue behind the walls in your home to your electrical outlets.

The falling water lands on a turbine which spins a generator.

Water, at the top of a waterfall controlled by a dam, has potential energy.

As the turbine (generator) turns, it moves copper wire along a magnet which creates a flow of electrons (electricity), which is then transferred to a wire. .
