We have 250g of potassium oxide. Atomic masses of potassium and oxigen are, respectively, 39 and 16g/mol. how many atoms of potassium do we have? How many atoms of oxygen do we have ?

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
