Our body contains potential energy from food we have eaten.
This chemical potential energy is transformed into the energy of our hands and arms as we rub our hands together.
As our hands move past each other and rub against each other, friction allows the energy to be transformed into energy on the surface of our hands.

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
