if anyone could help with either of these questions, it would be greatly appreciated, thank you (:

1) how long does a day on the moon last and why?
2) how many times larger does the Earth look if you were on the moon,compared to seeing the moon from earth? (provide calculation)

thanks a lot!
(:

Have you done anything on this yourself? I entered "a day on the moon" into google and got the answer quickly. (It is about a "moonth"!) And it is probably in your textbook.

As for the second question do you know the diameters of the moon and the earth? Do you know the distance from the Earth to the moon? You could probably look those up in your textbook or on google.

What would the circumference of a circle, with radius equal to the distance from the Earth to the moon be? What part of that would the diameters of the Earth and moon be? Do you see why that will give you your answer?

If that's not a typo, then that's a terrible joke! And I love it!
