Can we tell, by looking5vbcpgh+ pgwnw)33 4n at tk+.p(uf0ln 4cga it3-sxi uu9he population on the H-R diagram, that hotter main-sequence stipl -f+c( t3ux us9ai4uk.0ngars have shorter lives? Explain.  




参考答案: yes


本题详细解析:
Yes. Since the population of hotter starsr -0o pv:ius93vrpsv 9 on the H-R diagram is relatively low compared to other regions of the diagram, it seems to imply that these hotter stars stay on the ma0pvr9o pr-s v:us 9vi3in sequence for a shorter period of time and, thus, have shorter lives. (This also makes sense from a fuel standpoint, since these hotter stars will “burn” up their fuel more quickly.)
