Err, I am somewhat impressed that you get away on
Bugger, ThorGod did beat me to this...
Could we please, at least on this site where people are supposed to have at least little better clue of mathematics than the average population, round prices intelligently and not fall for that bloody '99$ is not 100 !" ?!?
I don't think that anyone would use the exact price tag for a laptop of, say, 699$ rather than 700$...
So, this is a 100$ tablet for all practical purposes and now get off my lawn you stupid advertisement goons !
*g* No, it's not balanced by the centrifugal force, since the centrifugal force doesn't exist. If it was balanced, the sum of both forces would be zero and the trajectory of the rocket/satellite/whatever would be straight. Turning means that you must have a force which in turn provides an acceleration which in turn changes the velocity vector. In the case of a circular orbit the velocity vector will only change it's *direction* due to the force, but not it's *value*, since both are at a right angle to eahc other all the time.
Ok, to be a little clearer:
The centripetal force to stay in orbit around the earth (and this is also needed for any circular (or curved) movement BTW) is provided by the gravitational pull of the moon/earth, e.g. the gravitational force.
Again, the force is directed towards the center of the (circular) orbit, hence the name centriPETAL.
You got it almost right.
Centripetal force IS gravity.
The centripetal force that is needed for any circular (or curved) movement is provided by the gravitational pull of the moon/earth, e.g. the gravitational force. They are not opposite to each other.

Considering how many people foget to switch their phone off every day and how much reception of texts or data packets takes places while it's in their pocket, I've always foud it quite astounding that obviously no plane has aver fallen from the sky and it was still considered being a security risk...
That said, social aspects of the issue set aside.
What about moving out of the US of A ? I hear there are other countries with running water now...
If you depend on driving a car to stay in shape either you are a professional rallye driver or the guy who spends endless time delivering stuff with a crappy old truck on winding backcountry roads. For the rest of us it won't make much of a difference IMHO...
If it's too hot, e.g. hotter than what's endurable with minimal socially acceptable clothing, I try to find a room that's a little colder to work in.
In any event, in any device, in any change, some human needs to be responsible for it. When it comes to my car, that someone can't just be me. When it comes to my sister, it can't be her. It's that simple.
True, wrong, wrong.
I would certainly trust myself with working on a car/plane/boat that I have MY ass in/on rather than anybody else. No one in the whole world does have a better reason to take special care than I do in this case and as an "amateur" I can spend the time and have an extra deep look at everything in general or a thing that has raised my suspicion in one way or another.
And I have certainly seen dangerously bad jobs done on cars by those "professionals"...
>Is that slightly better?
Yes, it is. He/she is going to get a live impression of me first rather than anything else.
>If there's something bad to learn about you, you're out of luck, no matter when you are googled.
If there is something to learn, knowing me in person firsthand might make a big difference on how this is perceived. This does not have to be the sex offender list, but my profession alone might be enough. If I was a physician, perhaps I don't want to hear people's medical problems immediately. I have been in situations where people told me afterwards that they would have treated me differently if they had known immediately that I was a foreigner. Prejudice against other nationalities and all. Once they realized first that I am a fairly normal person everything was fine all the way through.
Everyone wearing stupid Google glasses, in a dystopian future.
I hope I am not the only one here who would have an awkward feeling if I knew that someone I meet just did at least the equivalent of a Google search on me before we even talk.
And no, I don't give a fuck about sex offender list crazyness.
I do not want *anybody* to tell me who i should be afraid of or not.
