  1. If its based on the old A-Z then yes these have been available for time. I am always using http://www.streetmap.co.uk to plan my journeys. If you're interested in aerial photos then try http://www.multimap.com I believe the photos were shot using a helicopter that traveled the UK, and compiled a map of britain using the photos.
  2. You want brits to be thought of as eccentric people with emotional issues, suppressed by their wives and with a fetish for giving beats to people from Barcelona????? There are quite a few films that portray us badly but there are just as many if not more that portray us well. For example how cool is James Bond??? and with British films getting more recognition than ever (italian job, trainspotting, bend it like beckham, bride and prejudice, lock stock, snatch, etc.) I don't think a small scene in die hard will do much harm. I should think they see lots of TV over there too, including music artists, etc.
  3. In short, it is the mean angular velocity. I say mean because most orbits are elliptical such that the velocity changes depending on the radius at each point.
  4. http://www.geocities.com/bushatbooker/ ???? Probably debateable, but then all contentious stuff usually is. Take what you will from: http://news.bbc.co.uk/1/hi/uk/1522987.stm - Deployment to middle east 1 week before 9/11 attack http://www.thedebate.org/ - website questioning the ideas of the war on terror (Iraq and Afghanistan) http://news.bbc.co.uk/2/hi/programmes/newsnight/4354269.stm - Secret US plans http://www.alternet.org/waroniraq/21535/ - Secret US plans http://www.gregpalast.com/opeconthemarch.html - Secret US plans http://smh.com.au/articles/2002/10/06/1033538848021.html?oneclick=true - Foreign Policy Agenda http://www.mapsofworld.com/world-top-ten/world-top-ten-oil-reserves-countries-map.html - Top Oil reserves I can't deny I'm suspicious but there is no way of coming up with the answer as there will always be conjecture. As to pro-antiterror campaigns suggest 9/11 and the history of al-queda, saddam, etc. be looked at. Have fun.
  5. Sounds like the microbes that are naturally swiming around your eye, going across your line of sight.

    Linear Scale.

    Here we are http://mechanical-eng.mme.tcd.ie/~clyons/calibrations.pdf

    Linear Scale.

    Any instrument technician should be able to tell you (or someone that's had some instrumentation training) measuring instruments of this kind are not exactly linear. If you plotted the output of a measuring device against the known input, you'll find that the graph will be sort of exponential but curving off at the top. A bit like a culmulative frequency curve, not sure if there's a formula for it. There is section of this curve however that is more or less linear which is where the instrument is calibrated to by adjusting its "span" and "zero". In essence the scales will only work within their range on the display.
  9. Just a quick tip I've found when I feel a bit close wanting to meet the "porcelain throne", is to suck on an ice cube. And when you think its really close just clench on the ice cube a bit more. I don't know why but whenever I've had too much, this little trick has avoided any embarassing projections. And if you order the right drink you'll never be far from one.
  10. Hmmmm, takes me back to the days of my HNC eletronics . . .. last year. The 1st question has three choices to solve it, Norton's theorum, Thevein's theorum or Superposition theroum. The 2nd seems easier, as its simply ohms law. The power of the generator is given by its emf * circuit current, the dissipation rate is how much the resistance dissipates, and the chemical rate battery emf * circuit current. Efficiency is the power taken by the load (battery) divided by the power supplied by the source (generator)
  11. I can't see this. The flux is emitted in all directions like a light bulb. This flux acts onto a surface area to give luminance. Its, if you like, a measure of how much light is received from a radial source. The intensity is more linear in that it looks at how much "energy" there is at a given distance away. In this case the r refers to the distance from the point source. The formula should actually be I = L / {4 * pi * d^2}. The 4pi indicating where the steradian is. The formulas are used in different concepts, the 1st is as it is received on to a surface, the 2nd is how the source is perceived at a certain distance. Chalk and Cheese clearly even is it is both about light.
  12. It means inverse tan. Another way of writing it would be theta = 2 * arctan(h/2d) also d = h / {2 * tan(theta/2)}
  13. I still think the answer to a) is -40N The acceleration between the two surfaces is 2ms-2. So the answer to a) is 20kg x -2ms-2 = -40N I agree to the workings of b) and c) however. Only my answers would be b) Net force = 720N, Force F = 760N c) a = 7.6ms-2
