Given: The mass of electron is 9.11x10-31 kg, Planck constant is 6.626x10-34 J, the uncertainty involved in t measurement of velocity within a distance of 0.11 Åis
(a) 5.79x 108m -1
(b) 5.79x109 ms -1
(c) 5.26x10ms-1
(d) 5.79x107 ms -1

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

Ijust took the quiz. their is no coefficient needed. : )

Hi hi answer is and
