Astronomy physics questions I need answering urgently please.?

Hm. That sounds like a fairly respectable sopre astronomy test. Answering the first question requires that you understand spherical trigonometry (or just find and apply the formulas) and coordinate transformations. You might also need to reduce the orbital elements of Earth and Venus to determine the right ascension and declination of the sun and Venus on a specific date. I could do those things for you, but you really ought to do them yourself. I'd not help a woman seeking to become a firefighter over the obstacle course wall, either, even though it might be the one time she'd let me put my hands on her .
