One of the stable isotopes of lithium has 3 protons and 4 neutrons, so its atomic mass is 7. Assume that a lithium atom initially at rest radiates a photon of energy 1.8488 eV and recoils. How long does it take for the recoiling atom to travel 1 mm? Assume that the lithium atom travels in a straight line without any collisions. Note: 1 amu = 1.66 × 10-27 kg Be careful with the units! t =

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

Of course: ) what’s your name ?
