Physics

] Accreting, spinning, magnetized systems tendto:

  1. Accelerate
  2. Grow in mass
  3. Produce jets
  4. Produce supernovae
  5. Cannot be predicted

[28] If space had been found to be negativelycurved, the other evidence might have us conclude that:

  1. The universe will re-collapse
  2. The need for dark energy is even greater
  3. There might be little or no dark energy
  4. Omega =1 exactly
  5. None of the above

[29] The “anthropic principle” addresses theidea that:

  1. The universe seems conducive to life
  2. The universe is homogeneous everywhere
  3. The universe can be explained via rational explanations
  4. The study of cosmology is common to all human cultures
  5. None of the above

  1. The “principle of equivalence” states that:
    1. Masses of fundamental particles are the same everywhere
    2. All universes in a multiverse are similar  
    3. Acceleration in a gravitational field in similar to theacceleration by a rocket D) Mass and energy are equivalent (E =mc2)

  1. Type Ia supernovae are:
    1. Exploding neutron stars
    2. Exploding hydrogen rich white dwarf stars
    3. Exploding helium / carbon white dwarf stars
    4. Exploding massive stars stripped of their hydrogenenvelopes
    5. Exploding hydrogen-rich massive stars
