    the beta particle is formed in the nucleus, it is formed when a neutron is converted into a proton and electron

    Kinetic energy is transferred to the distortion of the shape also more time is given for the energy to decrease

    Question. What is nuclear fusion

    When a neutron is fired at Uranium-235 or Plutonium-239, releasing two smaller nuclei and two or three neutrons which cause a further nuclear fission by reacting in the same way.

    Question: how is a voltmeter connected in a circuit and why?

    potential difference is the work done between two points for the electricity to be transferred from one point to another?
