intrinsic magnitude


How do you know when a girl is tired of you?

She ignores you. When she does talk to you, she answers with short, quick, & cold responses. She avoids talking to you or any contact at all with you.


What should you do if someone you like ignores you?

Maybe your not spending enough time with them. Maybe you need to get noticed! How about if you just be yourself. They will eventually notice you, but if they don't I'm afraid they might not be interested in you? No one knows, but there is lot of girls out there so don't stick with one that doesn't want anything to do with you.


Does the sun's gravity affect your weight?

Technically, yes. But certainly not enough that you would notice it.In my drawer full of file folders full of articles that describe gadgets which I willbuild some day, there is one for an electronic thing that monitors minute changesin the force and direction of local gravity. But I mean really truly minute changes ...if you build it with enough care, so it says, you can see the daily variations thatare due to the over passing of the sun and moon. Now that's minute!The ratio of (your weight towards the Earth) and (your weight towards the sun)should beearth's mass/sun's mass times [distance to sun's center/distance to Earth's center]2 .When I plug some numbers into that, I get about 1,623 . So if, for your mass, yourweight on Earth should be 200 pounds, then the influence of the sun would makeyou appear to be something like 2 ounces lighter than that at noon, and 2 ouncesheavier at midnight. (This completely ignores any influence of the moon, whichprobably ought to figure into it too.)I used:Earth radius . . . 4,000 milesSun distance . . . 93 million milesEarth mass . . . . 5.9742 x 1024 kgSolar mass . . . . 1.989 x 1030 kg


Imagine a Earth-Moon-Sun system in which the moon was much smaller than the present Moon How would this effect solar eclipces as seen on earth?

The way things are right now a total eclipse of the sun by the moon is a pretty close match in size. The only part of the sun not covered by a total eclipse is the photosphere, and during a total eclipse is one of the rare occasions when scientists can observe it directly. If the moon was smaller you would see a ring of sun when the eclipse was 'full'. It would be more of a transition than a true eclipse.
