Research a process or a machine that changes mechanical energy into electrical energy. Create a document to show the energy conversion. Be sure to show all conversions and include labels. Choose another type of energy conversion from the list below.
Repeat steps 1 and 2.
electrical to mechanical
chemical to mechanical
chemical to heat
solar to chemical

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples

The force needed to overcome static friction is usually less than that needed to overcome kinetic friction.true or false?

Which statement best describes the superposition principle? a.) if two in-phase waves arrive simultaneously at a point, their amplitudes add up b.) if two out-of-phase waves arrive simultaneously at a point, their amplitudes add up c.) if two in-phase waves arrive at a point one after another, their amplitudes add up d.) if two out-of-phase waves arrive at a point one after another, their amplitudes adds up
