Hey! I'm taking my laptop into school to play music, but I want to lock my computer into iTunes so that other people can't get out of it, unless they have a password or something. Anyone got any ideas? I only want people to be able to access iTunes :)

Hey everyone :) I have a movie file on my computer that is 120 minutes and 800MB. I want to transfer that onto a DVD CD so that I can play it on a DVD player at my friends house. The movie file is in AVI format. How do I put that file onto the DVD CD? Do I need a special programme or...

My friend has laser eyes already, so I think we will evolve into x-men like creatures.

Hey:) I'm trying to think of ways in which Banks play a role in the economy as a whole, and what you would gain in terms of experience in the field of finance. I just wanted to know how those two areas of business are linked to Banking. Thanks!

Has anyone else wondered how long it took to come out?

I saw an advert on TV the other day asking for donations for people who's pensions have been destroyed over there. I remember I went there in 2000, when it was a lot better, but still bad. When they sold soft drinks in glass bottles, they actually refunded you nearly half your money if you...

I'm not sure. Is a mutation a result of evolution? :bugeye: Surely the initial variance in species would be due to a mutation, and through that mutation species have evolved and become more varied? I'm not 100% let's see what other people think. _Mayday_

Hello, I've been doing a bit of reading into Nicotine, but I am somewhat stuck. Any help would be much appreciated. Nicotine binds with Cholinergic binding sites, or acetylcholine binding sites. My question is how do they differ? Why is Nicotine addictive, if without it you have Acetylcholine...

3b) input current x input voltage = output voltage x output current 240V x input current = 5000 x 0.5 input current = 10.42A is this correct? 4a) i got 120 primary turns b) I used the formula from 3b) and i got 72 in the end. I would like some clarification here. thanks a...

Hello. 3) A step up transformer increases the mains voltage of 230V to 5000V. a) calculate the ratio Number of primary turns/Number of secondary Turns I know the formula input voltage/output voltage = Primary turn/ Secondary Turns So i did 230/5000 = 0.046. This as a fraction is...

Oh nevermind, I found another source, on the same site on like a fact sheet. They have like ranges, so I will average them I think, as I only want to gain an idea of trends etc.

From that table 2 I want to pick out 5 or 6 of the alloys say 2Ni-based 2Fe-based and 2Co-Based or something like that and then link those figures to the one on temperature and stress rupture. I thought something like A-286 NCF-3015 Waspalloy Pyromet 41 Pyromet 706 Is there another place...

Hey Astro thanks for the links, I will look at them now. On this link in table 1 under Fe for some of the alloys it says "bal." what does that actually mean? http://www.cartech.com/news/wr_age_harden_superalloys.html

Hey Again. Does anyone have any data that would tell me which materials where used in the turbine blades over time? Almost like an evolution of materials? I've found this incredibly difficult, and also with these materials I would like to be able compare things like tensile strength, melting...
