I currently am in the First Lego League Robotics Competition for my middle school, but soon I will be moving on to high school. My high school will not offer a robotics team, but I would like to continue with robotics as a "sport" as I complete my education. The prospect of battling robots interests me. Any help is appreciated.

A ball is attached to a flexible cord and swung in a horizontal circle. The angle between the cord and the horizontal is less than 45°.
(i) Which is larger, the horizontal force or vertical component of the tension force?
(ii) Which is larger, the vertical component of the tension force or the gravitational force?
(iii) Is the acceleration of the ball larger than, smaller than or the same as the acceleration of a ball falling freely in a gravitational field?

Please explain each. Thanks.

a)use function notation to write a cost equation for each type of bulb.
b)state the domain and range of each equation
c)after how long is the fluorescent bulb cheaper than the regular bulb?

The Galaxy! I want peoples theory on how it was created. It could be the Big Bang theory or just something you made up! I thinks it was always here and that it's old enough that no one will ever have the technology the see how old it is. Just so people know THE SUN'S GOING TO BLOW UP!!!!!!!!!!!!! But that's billion's of years from now and how people think in million's of years California will fall off, Global Warming will probably kill us first but that will also take a very long time. Not to worry anyone but hey it's true! To: Global Warming >:P

I mean there are all these instructions on how to do it and yet for some reason i pretty sure no one on this earth has accomplished anything yet. Why? and hypothiticly, if it did exsit then there would be a whole new kind/type of energy to study. Is there any scientifi proof of anykind of energy the brain has that can effect the physical world?

This happens a lot I can be talking about maybe a song I haven't heard in a lomg time and it suddenly starts playing on the radio. Or I could be changing a light bulb that just went out, and a light bulb ad comes on TV. Today I was looking at some UNICEF Xmas cards sitting in my bed room, and my 5 yr old grandson starting singing trick or treat for UNICEF in another room!

I am starting to wonder why whatever I am talking about,or even thinking about shows up on the air the same time I"am thinking about it. It's just too weird, and it is happening more and more often. Why is this happening, and how much can actually be summed up as coincidence, what are the odds?

I have just found a sort of insect on my sister's floor on a peice of food that i have found in my bed before but im sure its not a bed bug. It is hairy and shaped a bit like a bed bug and has small legs like a woodlouse. It is not at all big...about the size of a louse. It is dark brown with a little bit of white on the end...If there are any suggestions to what this is..please answer!!

Question was:
A fisherman and his young nephew are in a boat on a small pond. Both are wearing life jackets. The nephew is holding a large floating helium filled balloon by a string. Consider each action below independently, and indicate whether the level of the water in the pond R-Rises, F-Falls, S-Stays the Same, C-Can't tell. (If in the first the level Rises, in the second it Falls, and for the rest one Cannot tell, enter RFCCCC)

A) The nephew pops the balloon.
B) The nephew gets in the water, looses his grip on the string, letting the balloon escape upwards.
C) The fisherman lowers himself in the water and floats.
D) The fisherman fills a glass with water from the pond and drinks it.
E) The fisherman knocks the tackle box overboard and it sinks to the bottom.
F) The fisherman lowers the anchor and it hangs vertically, one foot above the bottom of the pond.
