If anyone could help it would be great! I am having some trouble on this assignment.

1)If you are standing on the moon will the phases of the earth be like those on the moon but only opposite? And will the earth rise and set like the moon?

2)T/F The occurence of solar and lunar eclipses disproves the notion that the sun and moon orbit around earth.

3)Say if you shot a cannon from Brazil to the equator, would the coriolis effect play a part or is it too close the the equator?

4)If the Earth were a perfect sphere with a radius of 6400km:
a)What is the distance at Earth's equator that corresponds to 1deg lat. and 1deg long?

b)Estimate the distance corresponding to 1 deg of long. at lat. of 30deg and 60deg

c)What would be the distance of 1deg of lat at these same latitudes?

Any help would be great especially on that last one. Thanks!
