if i know uranus' orbital period, i know its distance from the sun and it moves from opposition to quadrature with respect to earth, how do i work out how long it takes to move between these 2 points. a circular orbit is assumed.

radius = 19.23 AU
sidereal period = 84.33 years
synodic period = 1.012 years

i feel like this is such a simple thing to do but ive ran out of steam tonight.

cheers.

iron (III) ions in water reacting to potassium thiocyanate.

if the reaction is large then does that mean that there is a lot of iron in the water? and if a small reaction occurs then there is a small amount of iron in the water? why?
if you have a website so i can site it from it would be helpful but if you don't then it's fine.

A star creates an absorbtion spectrum because when light given off by the hot solid, it passes through a cool gas. Then, how come when we look at our sun, it is a continuous spectrum? I asked my teacher this, and she didn't know why. She told me to look it up myself for extra credit, but i can't find it anywhere. Please answer ASAP. Thanks!

The Circumference C if a circle and it's diameter d are related by the equation C=(pie symbol)d.

ok i have no idea my math teacher didnt explain this to me. can you help me understand better.

Hi i have a scince fair in March and i have an idea for it. What if i got frog legs and tried to harness eletricity to them and make them move?!?! how would i do that? getting the legs is no problem, but which kind should i use? ( i am not killing a live frog) and if this wont work please igve me winnning science project ideas thanks.

burn? How easy/difficult will it be to ignite with the flint?

Yes, I KNOW that there are other ways and other things I could use, but please answer this question before you start asking why I didn't ask where to buy a butane lighter.

On a related topic, (optional question for extra credit) I've seen liquid fuel lighters with flint igniters and gas fuel lighters with piezoelectric igniters, but I've never seen liquid fuel lighters with piezo igniters or gas fuel lighters with flint igniters. I've even asked Zippo representatives at tobacco shops and they're clueless. Anybody know of a reason why the alternative variants wouldn't work? I'd love to have a lighter where I never needed to replace the flint, just fill it with fluid every so often.

Paleogravity is the theory that the apparent low-gravity characteristics of dinosaurs ("too heavy to support their weight on land") are due to an actual lower surface gravity of the planet beyond 65 million years ago. I have proposed that this was possible due to higher core temperatures, and therefore an expanded Earth volume. Thus, the dinosaurs would have lived in the gravity zone where some of our satellites orbit today. So, how do I calculate the number of miles the Earth's radius would have to increase to reduce the surface gravity by such-and-such a percentage? I used to study analytic geometry but that was some years ago... I'm going to start re-learning that but thought I would throw this out there in case anyone else is willing. Some other fellas and I are arguing the theory at:
