Homework Statement Say if you have water in the bucket and you spin it around really fast creating a vertically cricle. How come it won't fall on you when its at the top? Homework Equations The Attempt at a Solution

Okay I understand but I was wondering if I could do it in a private school where the course is easier then in day school? Cause I know a private school where the tests are easier compared to day school? So do you think I need to know the basics of grade 12 SCH4U or as much as possible...

My question is do I need to be exceptionally well in chemistry 12 university level course when going to university next year. I am planning to go into civil engineering next year in university; It deals with structural and transportation systems? All advice is appreciated.

yea sure I will do that but the book literally states in answers(unless they are wrong) 4.5a=3.19x10^9 secondsi will try one more time thanks for your help I think I will speak to teacher about this question, maybe something is wrong with it

yes that is the whole question and you are right it does not tell you the frames...Im guessing you are suppose to figure out the frames yourself.. d from Earth to star= 4.3x10^16 m v= 0.999c=3x10^8x0.999=2.9997X10^8 I used the distance time formula to find the ts(well I think the...

Homework Statement Alpha Centauri, the closest star to Earth, is 4.3x10^6 m away. How long would it take a spaceship to reach the star if it were traveling at 0.999c? Homework Equations I did get the answer as 0.2a...and the textbook also said it would take about 2 months, I do not...

yes that is what I did; My information(list), I gathered from the text; I guess I will go back again and read it over one more time. ---thanks

Homework Statement List the 4 properties and characteristics of electric field lines. Homework Equations I was not able to get them all and the ones that I did get I am confused that if it is really a characteristic or a property The Attempt at a Solution 1. Characteristic...

Its not that I don't think it WONT be conserved but rather I do not understand how? I mean what do elastic collisions got to do with an elevator that will move up in a very powerful electromagnetic field(i think).

yes i realized my mistake and I would edit it but I cannot... Either way. my main question of 'discussion' was how would the conservation of momentum and energy be applied in a space elevator.

NASA did not state; but through an article I found was compiled someone who must be part of NASA? Unless if you think the article has false data: Check it out: http://www.spaceelevator.com/docs/elevator.pdf On page 2 he does state: " Advances in these five areas over the next 10 to 20 years...

You are right. I worded it wrong. However, NASA did state that this project will be completed in about 15 years

I want to know what exactly is the free-electron laser power beaming system that will be used in our future Space elevator and how the conservation of energy and momentum is associated with this project that NASA will launch. ? Other info: I am taking grade 12 university level physics; All...

*How do I make new posts?

that was a good explanation thanks for the answer and forum info.. one last thing(you might laugh but) how do I my own post lol still can't figure it out...
