McGehee, P2. If you are standing in California and your friend lives in Alaska, and you are both observing a particular starat the same moment, which coordinate(s) would be the same for both of you?Same Not Sameа.Zenithb. North Celestial Poleс.Altitude of stard.Azimuth of starе.HorizonfEcliptic1,

We are authorized to answer three subparts at a time since you have not mentioned which part you are looking for, so we are answering the first three subparts, please repost your question separately for the remaining subpart. California is the United States which is specifically on the western side of the United States and Alaska is more of the Northwestern part of the United States. There are certain parameters like Zenith or North celestial pole on the basis of which both states coordinates can be compared. A. The zenith is basically the star altitude height just above an observer. It is basically the subtraction of angular distance minus the altitude of that place. Being in different altitudes Zenith would not be the same for California and Alaska. B. North Celestial pole is the ideal extension point that directly overlies the observer,s head and that is an imaginary point that has been extended in both North and South directions in space. This would be the same for both California and Alaska. C. Altitude of a star depends on the latitude of the location and angle of the star from the horizon point. Star angle is equally maintained in both directions, North and South like any star is North having 45o angle more then it has a 45o less in the South. So it would not be the same for California and Alaska.
