WHAT CAUSE AN ELECTRON TO OCCUPY A HIGHER ORBIT?? Do you really mean an electron or are you really referring to a planet or satellite since the title of your post is astronomy? If you really meant a planet or satellite: Consider a satellite in a circular orbit around the earth...

1.If you mande a model of the solar system with the Earth. The size of a tennis ball [about 6.5c.m in diameter] How big would your model of the sun be? 2.How far away from the tennis ball Earth would your model Sum be.If you kept the size and distance to scale? Since the Sun's...

gimme a side of what physical science is. I know there's no shortcuts but it means alot of ev'rything I gotta know. Sho' me. I have little understanding of what you wrote. When one tries to communicate in non-standard English, the results are unpredictable. Here is a ...

Two stars in a binary system are determined from their position on the H-R diagram and the mass-luminiosity relation to have a combined mass of 8 M. Their orbital period, P, is 1 year. What is their orbital seperation, a? http://en.wikibooks.org/wiki/Astronomy/Mass

Thank you for using the Jiskha Homework Help Forum. Hopefully you can find that information in the following Venus fact sites: 1. http://mars.sgi.com/worlds/CyberMarz/Venus/HTML/index.html 2. http://library.thinkquest.org/29033/solarsystem/venus.htm 3. http://nssdc.gsfc.nasa....

Need some help with Astronomy. I need to figure out the acceleration of gravity on the surface of certain planets. For example, I need to find the acceleration of gravity on Mars when the mass is .11 times the mass of Earth and the radius is .53 times the radius of Earth. ...

Both. The acceleration in a crash is high because one or both vehicles had a high velocity to begin with. Seat belts actually provide the force necessary to decelerate the body. It is better to have the force applied to the body by belts than to the head by a windshield. I don...

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?

what good has astronomy produced?

Few question about astronomy: 1.how 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

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...

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.

This is definitely NOT my area, so here are some Astronomy Tutorials (quasars) to go through: http://www.google.com/search?q=ASTRONOMY+TUTORIALS+-+QUASARS&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a Sra

The parallax angle, in radians, is the ratio of the Earth orbit diameter to the stellar distance. It is the size of the angle that the stellar position changes relative to stars much farther away, during the course of a year. Read this for a good review: http://www.astronomy....

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

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.
