what is the meaning of astronomy?
Sunday, August 28, 2011 at 3:32pm by Anonymous

The first thing you should learn when studying astronomy is that it is not astrology. Astrology is not a science. Objects weigh about 1/6 as much on the moon as they do on Earth.

At a more northern latitude, but still in the southern hemisphere. Figure out how many degrees of longitude correspond to 100 km and add it to -45. It's roughly one degree. Is this really what they are considering astronomy these days?

This sounds more like geology (or planetary studies) than astronomy. Presumably the direction of plate motion changed where there is a bend in the chain. So.. Divide 4000*10^3 m by 0.08 m/year. You get 50 million years.

Few question about astronomy: many centimetres is equivalent to a light-nanosecond 2. How long is an astronomical unit (AU) in light-minutes (1min, i.e., the distance that light travels in a vacuum in one minute)? Please show the calculation if there is any Thanks

Intro to Astronomy
If 1% is left, (0.01) = (0.5)^N where N is the number of half-lives. N = 6.644 minimum age = 37,900 years There will be less than 1% left if the sample is older than that, so that is a minimum age. There is not much about astronomy here

As I said in my answer to your other question, you must insert a ^ before exponents. you are not going to learn much astronomy with sloppy equation writing. (a) Divide the Jupiter-sun distance (in km) by the length of 1 a.u. (also in km). That will give you the number of au's...
