For each statement concerning main sequence stars, select T True, F False, G Greater than, L Less than, or E Equal to. A) The surface temperature of a O type star is .... than a K type star. B) On the main sequence, the mass of a O type star is .... than a F type star. C) On the main sequence, a M type star's life is .... than a G type star. D) The surface temperature of our Sun is .... than the surface temperature of Sirius. E) When stars start hydrogen burning, thier mass determines where they are on the main sequence. F) Based on the relative lifes of M and G type stars we expect the number of M stars to be .... than the number of G type stars.
The Sun emits 3.839 x 1026 J of energy every second, which is generated from the fusion of hydrogen into helium in its core.  Using Einstein's equation E = mc2 (with c = 2.9979 x 108 m/s), determine how much mass the Sun converts to energy every second due to nuclear fusion in its core.  If we assume that the Sun has been shining at this same rate through its entire 4.6 billion year history, how much mass has the Sun lost due to nuclear fusion during its lifetime?  Express your answer as a fraction of the Sun's current mass (1.9891 x 1030 kg).
As a cluster of stars begins to age, which type of star in the cluster will move off the main sequence of the H-R diagram first?   1) all the stars in a cluster are born at the same time; so they will all move off the main sequence at the same time, as they evolve   2) G type stars, like our Sun   3) M type stars, which are the coolest   4) the lowest mass stars, which have the least amount of fuel for fusion   5) the O and B type stars
