Physics - Coggle Diagram

- - - - Chadwick discovered the neutrons
  - - - Very ionizing but don't penetrate very far into materials
      - Helium nuclei - two neutrons and two protons
    - - Fast moving electron and a neutron turned into a proton
      - Moderately ionisng and penetrate moderately
    - - Waves of em radiation
      - Weakly ionize but travel far
  - - - When am object is exposed to radiation
    - - is radioactive particles getting onto other objects
  - - - One neutron fired in and then two smaller elements and some more neutrons are released as well
      - Energy produced can be used to heat water for turnbines to turn electricity generators
    - - Two lighter elements are joined together to create a heavier nucleus and some of the mass turned into enrgy
- - - - The voltage is directily propotional to the current
    - - High resistance in one directional, no resistance the other
    - - Bright light, resistance falls
      - Dark, resistance is high
    - - Hot, resistance falls
      - Cool, resistance is high
  - - - Connected End to end
      - VOLTAGE SHARED
      - CURRENT SAME
      - RESISTANCE ADDS
    - - VOLTAGE SAME
      - CURRENT SHARED
      - RECIPROCAL RESISTANCE ADDS
  - - - Current switches direction
    - - Current going in one direction
