Explanation / Answer

11.a) 31 arcmin, 0.5 degrees Explanation: (both moon and sun have similar angular size when observed from earth. 13a) total eclipse. 13b) Annular eclipse Explanation: when moon is near to earth, it is away from sun and sufficient enough to hide the sun and thats why it is called total eclipse, when it is near to sun and away from earth then it cannot cover the sun and hence a small circular portion of the sun will be visible around the moon in annular eclipse. 14.a) umbra Explanation: observers within the umbra can observe a total eclipse of the Sun where the Sun is hidden by the moon completely. 14.b) partial eclipse.
