Suppose some radon gas enters your home. The half-life of 222Rn is 3.8235 days. What percentage of the 222Rn gas would still be present 6 days later (assuming it is only dissipated through nuclear decay)? Report your answer in percentage to one decimal place.

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
