General Knowledge!

[·WídgêT·]

I thought the question itself was pretty simple, but since I'm also studying Aerospace Engineering then it makes sense why some people wouldn't really get the question. Just thought I'd post a question that interested me is all 

I propose this: since im 99% positive Enigma knows this he can feel free to answer, and he can propose a question that's more 'general,' fair?

geocentric and .... ummm...

They are clearly given by, within good approximation (assuming the earth dominates the gravitational force), the following differential equation:

They are types of elliptic functions, of course.

Hmm, I should have simplified that a little more to combine some terms, but meh.

three60's answer is also stolen from Chamber's 2011.

You unscrupulous person!

I vote Widget goes.

You honest person!

Of course.

Goes without saying.

You really should have.

So messy.

Assuming we are talking about satellites orbiting earth.

Polar Orbit
Satellite orbit that passes over, or very close to both poles of the Earth. During a 12 hour day, a satellite in such an orbit can observe all points on the Earth. Polar orbits are 90 degree inclination orbits, meaning that the orbit is at 90 degrees to the plane of the equator. As the earth rotates this enables the satellite to pass over all longitudes. The path of the satellite's own orbit allows it to pass over all latitudes.

Equatorial Orbit
zero degrees inclination to the equator - allows for the fastest revisit time

Geosynchronous
Matches earth's rotation and speed so the satellite can remain over the same area. It is an equatorial orbit.

There are also designations for altitude: Low Earth, Medium but don't think that is what you were looking for.

Of course.

What, it's true *shrug* Same for a pendulum, though different kinds.

LEO, GEO, etc. were actually the first that came to mind but like I predicted you would have the answer, have at it Enigma

How about Hockey:

One NHL team won 5 consecutive Stanley Cups any idea which team and the years?

bonus question: Two teams won 4 consecutive any idea on the teams and their years?

[BFM_Kiwi]

The only "dynasty" type teams I can think of recently are the NY Islanders and the Edmonton Oilers in the late 80's and early 90's, and Detroit in the last decade or so.  I really don't think any of them won more than 2-3 in a row though. 

Montreal, Toronto and Boston would have had good teams in the 70's or 80's (and earlier), no idea how many they won.

I'd guess Boston in the Bobby Orr years (no idea what decade that was, 60's?) or Montreal in the 60's or 70's.

Good one
Montreal 55-56, 56-57, 57-58, 58-59, 59-60

Now this
Montreal 75-76, 76-77, 77-78, 78-79
NY Islanders 79-80, 80-81, 81-82, 82-83
well this one to Ottawa 1902-03, 03-04, 04-05, 05-06

Good one
Montreal 55-56, 56-57, 57-58, 58-59, 59-60

Now this
Montreal 75-76, 76-77, 77-78, 78-79
NY Islanders 79-80, 80-81, 81-82, 82-83
well this one to Ottawa 1902-03, 03-04, 04-05, 05-06

Wow!   Looks like we've got a real NHL fan here, folks!

I think he got them ALL, and with their years, too!

 

[BFM_Enigma]

I knew Rick would get this one, if he noticed the post . Good job

Only team to win 5 straight Montreal in the 50's/60 Rick has the years correct.

Later, Montreal and New York Islanders both won 4 straight, again Rick has the years correct.


Rick you are up !!
