    Calculating Gas Disturbance from a Supernova Explosion

    hi guys many thanks in advance for any help, I am revising for an exam and got stuck on this question: "A supernova of energy 10^44 J explodes in interstellar matter of density n0 = 10^6 m^−3 and pressure Pi = 3*10^−14 N m^−2. Estimate how much gas (mass) can be disturbed by this supernova...
