For each statement concerning main sequence stars, select T True,FFalse, G Greater than, LLess than, or E Equal to A) On the main sequence, the mass of a K type star is than a B type star. B) The surface temperature of our Sun is than the surface temperature of Sirius. C) Based on the relative lifes of M and G type stars we expect the number of G stars to be than the number of M type stars D) On the main sequence all stars start with almost the same mass. E) The surface temperature of a O type star is than a K type star. F On the main sequence, a M type star's life is than a G type star. Answer: LLGFGG Submit All Answers /5 Not yet correct, tries 1 Hint: More massive stars are brighter (because they are hotter and burn up faster. The mass of a star determines where it lies on the main sequenceExplanation / Answer
A) Mass of K type is less than that of B type star in main sequence (L)
B) Surface temperature of sun is about 5000 K, that of sirius is 9000 K, so surface temperature of sun is less than that of sirius (L)
C) AS M type stars are bigger in size than G type stars, and bigger stars get consumed faster
hence, number of G stars are more than number of M type stars (G)
D) False (F)
E) Surface temperature of O type star is Grater than that of K type star (G)
F) M type stars have lower lifetime than G type stars as they are bigger and bigger stars get consumed more readily
so, (L)
