choose A B C D QUESTION 1 Star formation in giant gas clouds is a result of competition between which forces? Light and rotation Light and dark Rotation and gas pressure Gravity and gas pressure 10 points QUESTION 2 What effect sets the largest size a star can have? The forming star is shining so strongly that it blows the collapsing gas cloud apart. If the star was any larger it would instantly form a Black Hole. If the...

Question 1 1 pts Which one of the following statement is correct about the stars with mass equal to 10% of the solar mass? they are the most common type of Cepheid variable stars objects of 10% of the solar mass cannot be stars all stars of that mass, no matter when they were formed, are still on the main sequence of HR diagram. at the end of their evolution they will become neutron stars at the end of their...

QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

choose A B C D QUESTION 5 When astronomers look at globular clusters they don't see any stars hotter/more luminous than our Sun. What does this mean for the age of the globular cluster? The globular cluster doesn't have enough gravity to capture any stars more massive than our sun yet. The globular cluster is younger than the typical lifetime of a star like our Sun. The globular cluster is older than the typical lifetime of a star like our...
