What is the typical main sequence lifetime of a G-type star?

In the figure below, indicate the type of spectrum shown.     

In Figure C, which star is hotter?  

The absolute magnitude of a star is its brightness as seen from a distance of:

The pattern of rising hot gas cells all over the photosphere is called:

Describe 2 specific concepts or exercise techniques/principles that you hope to continue long term and how you plan to incorporate and why (e.g. name of exercise or principle or concept then explain what specifically you will use the exercise, principle or concept for in your daily work, life or school).    An example of good– and no you don’t get to use this example — “I want to use High Intensity Interval Training more frequently in my weekly workouts to increase cardiorespiratory fitness in a short amount of time.  I will add some form of intervals as finishers to my 3 x week strength training  routines.” An example of bad:  “I want to continue progressive relaxation because it makes me feel relaxed.”  Well why, how and what part makes you feel relaxed?  

Below is an incomplete table of information on 3 main sequence stars. Using the HR diagram below, determine the missing piece of information in cell ii.)  

The critical temperature the core must reach for a star to shine by hydrogen fusion is:
