Very interesting. Thanks for the help.

Ah yes, my bad. Plus or minus one? So I could in theory get that thing to equal 1, but that doesn't mean the product of this and the sine of a sine function is maximum does it?

Homework Statement A mask with 2 slits is illuminated by a light of 589nm wavelength. Slits each have a 0.1mm width separated (centre to centre) by 3.0mm. Calculate the distance between adjacent bright fringes on the screen if a screen is placed 5.0m away from the slits. Homework...

If eight flashlight batteries in series have an emf of about 12 V, similar to that of a car battery, could they be used to start a car with a dead battery? Why or why not? My friend posed to me this question and then I just sort of stumbled and was dumbfounded. I answered it by saying the...

I'm fine solving DE with a reducible quadratic, but what happens when the quadratic is irreducible, how would I go about solving the DE? So for example, \frac{dP}{dt}=-P^{2}+10P-26 Thanks in advance.

Hey all, Just a bit of background info: I'm doing an investigation on low temperature plasmas and one of the things I've come across is that electron temperature is always much higher than ion temperature. Now I believe one of the reasons that causes this is that ions lose a lot more...

Wow Genius! Thank Youuuuuuuuuu! Love You Mannnn! Love You Soooo Sooo Much! ^_______^

Homework Statement Ok, given 3 planes pi1, pi2 and pi3 with vector equations r.n1=0, r.n2=0 and (r-a).n3=0 respectively, where a, n1, n2, n3 are given vectors. No 2 planes are parallel and the third plane is parallel to the line, L, given by the intersection of planes pi1 and pi2. Consider the...

Well, thanks for all your unconditional help everyone. I think I've got some new ideas now even though I still don't know what to do with the apparatus. Yeah, I guess we'll stop here now.

I think it MAY be trying to get to the atomic model. Like, they'll try to be as far apart as possible. However, since they're hung together, it's like the nucleus holding the electrons together... And 4 charged particles... all of the same charge? Otherwise, the tetrahedral shape... So like...

I've thought about a video camera, but the quality is not as good as a picture camera... Plus, I can't put a video on my paper. O.o and explaining what I've done would take up 2000 words... Pointless talk, so yeah. I think Multi-flash would still be better than a video. Which still doesn't solve...

However, my question remains un-answered. I need an apparatus other than the multi-flash camera, which will be troublesome to borrow from school and move around, to determine the varying velocity in the horizontal dimention with a certain initial velocity (also need to be found by the...

Ok, this is what I have in mind. I am writing my extended essay (IB) on badminton. Firstly I'd like to find the coefficient of drag by measuring the terminal velocity (dropping cock vertically down) with a multi-flash camera and then subbing into the drag equation. I really want to use the...

utterly confused by taht equation, but if it helps to determine the range of the shuttlecock (which is the final aim of the whole essay) at given the initial velocity and angle then I better understand it. Still, how do any of those equations help me come up with an experiment that will record...

Which is also what I'm trying to do. If I can find the acceleration of the cock at any time by experiment, I can find the force of drag (since i can find out the weight force of the cock) at those certain times. Now the other problem with integration to find the range of the shuttlecock is that...
