A person moves a book from a 30-cm high coffee
table to the top shelf of a bookshelf approximately
2.5 m high. Which statement correctly describes
the gravitational potential energy of the book?
•It has more gravitational potential energy on
the table than on the shelf.
•It has more gravitational potential energy on
the shelf than on the table.
•Its gravitational potential energy is constant
regardless of its position.

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.

Aconductor easily transfer heat

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
