When gina was ten, she swam in the ocean for the first time. she remembers the feeling of kicking her feet, slicing her arms through the water, tasting the tangy salt water, floating her on her back, and learning from her father that salt water is more dense than fresh water, which makes floating easier. which element is a semantic memory?

First you need to know what is a semantic memory
Semantic memory, is a more structured record of facts, meanings, concepts and knowledge about the external world that we have acquired.

So ,The element which is a semantic memory is learning from her father that salt water is more dense than fresh water.

Hope this helped :)

Must be negative.substance increases

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
