thanks, i didnt know about wikipedia :approve: I've added it to my favourites thanks x

How does other galaxies differ from out own?

What is the distance to the nearest star? Is the nearst star Proxima Centauri (and it being 4.3 lightyearsaway)? Whats the Distance across a galaxy and the size of te observable Universe? :bugeye:

hey, doing some revision and am getting slightly confused. When Rutherford did his experiment when did deflection occur and when did defraction occur? Is it when a alpha paticle is fired through gold foil (10^-6 thick) it defracted, and when alpha is fired through a necleus it deflected. Any...

is it: Q2 = ((n/2 * f)/fc) * c b - lower class boundary f - sum of all frequencies below b fc - frequency of the class width containing quartile required c - class width of required class n - total frequency

I was doing some last minute skimming through my book for my exam tomorrow and panic. Can someone please please tell me about finding the median by interpolation and perhaps an example of how it would could used or asked, i will be forever greatful :cool: yasmin x (i can only find a...

gee u got this paper early

:blushing: I am getting confused. electrons, protons, which finger goes where in the left hand rule... agh! lol, I am muddling myself all up. i understand the rule (well i hope i do by now as that means the rest of my homework is wrong) but the last question of my h/w is almost killing me...

thank you :smile:

Hey, I am stuck on a question on capacitors, I have been doing physics all day so my brain might just be fizzled out a bit, but it is bugging me so if anyone could help it would great.Thanks, A 50 μF capacitor is charged by connecting it to a 6V battery then discharged through a 100kΩ...

thank you!

sorry just read the sticky after posting This is how i attempted to do it, but then realized how completely stupid and random it was F/Q = E = V/d -> v/o = (2.1 x 10 ^ -3) / 2 -> 1.05 x 10 ^-3 (1.05 x 10 ^ -3) / 0.068 = (2.1 x 10 ^ -3) / Q Q= (2.1 x 10 ^-3) / (1.544 x 10 ^ -3) =...

I am stuck on my physics homework. I can manage the latter question, how ever when i work out the first one my working out has no rhyme nor reason (nor a right answer). Any help will be great. A small metal sphere on an insulating rod is placed on a top pan balance, as shown in the diagram...

hmmmmmmmm [FONT=Comic Sans MS]:frown: are you sure that will happen, as my physic's teacher hinted at using superglue :confused:, - if this is the case techniqually, would we loose marks in planning to use this as it is really just a theoretical experiment (as it were) as we arent really...

Is what you mentioned both parts of the experiment?
