The modern model of the atom shows that electrons are(1) orbiting the nucleus in fixed paths(2) found in regions called orbitals(3) combined with neutrons in the nucleus(4) located in a solid sphere covering the nucleus

The correct answer is 2. Electrons are found in regions called orbitals. These orbitals are neither fixed paths nor solids, but are better visualized as cloud-like space, making 1 and 4 incorrect. Additionally, 3 is incorrect because the orbitals are outside of the nucleus, while the protons and neutrons are inside the nucleus. Hope I helped! :) Cheers!

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
