• The life cycle of a star common mistake 1

  Giving a vague answer instead of directly addressing: (Physics only) Explain that a main sequence star is stable because the forces within it are balanced..

  Fix itAnswer by clearly explaining how to (Physics only) Explain that a main sequence star is stable because the forces within it are balanced..

• The life cycle of a star common mistake 1

  Giving a vague answer instead of directly addressing: (Physics only) Describe the balance in a main sequence star as gravity acting inwards and pressure from fusion energy acting outwards..

  Fix itAnswer by clearly explaining how to (Physics only) Describe the balance in a main sequence star as gravity acting inwards and pressure from fusion energy acting outwards..
