  16. 4. The breaking of atoms nuclei through reaction is called… HINT 1 2 3 4 5 6 7 8 9 10 Exit Incorrect In Nuclear fission atoms are broken apart and energy is expelled. next back

  17. We use this in power plants… 1 2 3 4 5 6 7 8 9 10 Exit back

  18. 5. According to Hydrostatic Equilibrium the layers of a star are… HINT 1 2 3 4 5 6 7 8 9 10 Exit Thick Balanced with weight and pressure Pushing into each other Total masses equal the sum of all the masses

  19. 5. According to Hydrostatic Equilibrium the layers of a star are… HINT 1 2 3 4 5 6 7 8 9 10 Exit Correct! Thick Balanced with weight and pressure next Pushing into each other Total masses equal the sum of all the masses

  20. 5. According to Hydrostatic Equilibrium the layers of a star are… HINT 1 2 3 4 5 6 7 8 9 10 Exit Incorrect Pressure from the lower layer and weight from the upper layer help keep the balance of a star next back

  21. Equilibrium means balance 1 2 3 4 5 6 7 8 9 10 Exit back

  22. 6. Where do Neutrinos come from? HINT 1 2 3 4 5 6 7 8 9 10 Exit The core of a galaxy The core of our Sun The exterior of Saturn’s rings Dwarfs
