How long would it take to make a gram of gold with a particle accelerator?

They carry out the exchange of gases as we breathe ( oxygen and carbon dioxide).

Particle exchange energy though elastic collision , hope this .

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
