The north star was 2/3 of the way up the horizon, while (sun directly overhead) you heard that it was 10 pm in London where would you be?

OpenStudy (anonymous):

missing some astronomical information there, what are you assuming ?

OpenStudy (anonymous):

If you got lost at sea, and Polaris (the north star) was 2/3 of the way up the horizon, while at local noon (sun directly overhead) you heard on the radio that it was 10 PM in London, where would you be

OpenStudy (anonymous):

yeah but this has to assume something such as : where is polaris situated when you are at london at 10 pm. you are missing this kind of information in order to do the question. or at what time does Polaris appear in which position. ill give you an example with a known star : Sun

OpenStudy (anonymous):

if sun is at 2/3 of its place when its noon at london. it means you are at 2/3 of the 12hours... thus 6 hours away from london... its either 6pm or 6am... get it ? you are missing info on polaris or you are just not mentionning it and i honestly dont feel like making a reserch now lol

OpenStudy (anonymous):

if its 6pm or 6 am in that time zone, it should indicate where it could be: in that specific time zone... in the case of the star, you know its durring the night otherwise you wouldnt see it

OpenStudy (anonymous):

so... i hope u get the point

OpenStudy (anonymous):

this is all the gave me on the worksheeet.... hmmm i do get you but this is all they wrote down on my homework.

OpenStudy (anonymous):

i wrote the whole question down the second time

OpenStudy (anonymous):

ok let me think of this in a simplet way because in reality it is MUCH MUCH more complicated than simple math lol... it depends on the time of the year... bla bla bla... give me a few mins

OpenStudy (anonymous):

omg thank you so much! (:

OpenStudy (anonymous):

hello u still there?

OpenStudy (anonymous):

loooooooooooooool yeah

OpenStudy (anonymous):

i was killing myself researching this lol... i completely ignored the " while at local noon (sun directly overhead) you heard on the radio" part which is the most important

OpenStudy (anonymous):

i almost thought ur teacher is an idiot because this is impossible to resolve lol but i just didnt read the question fully.

OpenStudy (anonymous):

OK ! listen buddy. the question is indicating to you your Latitude and Longitudinal Coordination okay ?

OpenStudy (anonymous):

The sun will tell you you Longitudinal Coordination, and Polaris will tell you your Latitudinal. do you follow me until now ?

OpenStudy (anonymous):

if polaris is at 2/3 of the horizon, it means YOU are at 2/3 of the north hemisphere. do you get this ? (this is because Polaris is in the NORTH pole and will always be, and will never move.)

OpenStudy (anonymous):

because if you were in the SOUTH hemisphere, you would NOT see Polaris.

OpenStudy (anonymous):

the missing information was : WHAT IS POLARIS ???

OpenStudy (anonymous):

polaris is a star that never moves in the sky, it points the NORTH, ALL THE TIME.

OpenStudy (anonymous):

if you are in the south pole, you can not see it. if you are on the north pole, it will be straight up your head.

OpenStudy (anonymous):

THUS, if you can see it it is because you are in the NORTH hemisphere, more precisely at 2/3 !

OpenStudy (anonymous):

ok i get. it thank you... i have 2 other questions i need help with they are my last two.

OpenStudy (anonymous):

i will post them

OpenStudy (anonymous):

ok but i need to go. glad you understand.

OpenStudy (anonymous):

k thanks so much

OpenStudy (anonymous):

no problem.
