A synchronous rotation is when the moon or other such object has the same face towards the object which it is a moon of or which it is rotating around.

Our moon is a good example in that as the moon rotates around the Earth it rotates on its axxis in such a way that the same face of the moon faces the Earth. ( I know that there is a extremely slight difference BUT we see basically the same side of the moon )

I rrecently read that most moons have this same property in that the same face of the moon faces the planet or other object which it rotates around.

Is there some well know reason for this and what is it called (if it has a special name ) and or what would I search for other than synchronous rotation

Face it, if a person was cloned from another person who has no real country, would they person be illegal by American standards? The cloned person wasn't born, but created by science. What's your own thoughts on this matter?

Multiply:
(√[3] + 4√[5])(2√[3] – √[5])

Please show steps as I can not seem to figure this problem out. You do not have to give the final answer, just help me get on track with the way to work this problem. Thanks all in advance.

Is a geometric distribution a reasonable probability model for this case?


Suppose that one of every 100 people in a certain community is infected with HIV. You want to identify an HIV-positive person to include in a study of an experimental new drug.
Explain why or why not a geometric distribution is reasonable probabilty model for this case? Give your reasons


Also, if you can...How many individuals would you expect to have to interview in order to find the first peron who is HIV positive?

In an RC circuit diagram, if there are two capacitors on either side of a corner, but they are not parallel, would they be considered a series?

I'm not sure if my description makes sense, but I don't know how else to explain it...maybe, imagine a square, and stick one corner in between the two capacitors...
