In technical safety terms, combustibles are harder to ignite than flammables. So diesel and olive oil are combustibles, for example, because neither of them give off enough ignitable vapour at room temperature. Ethanol does, so it gets classified as flammable, and you need to store and handle it more carefully than diesel. Then there's really horrible stuff like triethylborane which will catch fire upon meeting oxygen even at temperatures well below the freezing point of water
Of course in casual usage they mean the same thing
That's part of the "make appropriate estimates" bit. You can just pick any reasonable number for the angular resolution Legolas needs and answer the question using that. Provided you do the method right, you'll get the marks.
Your pupil is functionally the same as the aperture on a camera. Whenever light passes through an aperture, there is some diffraction that happens to it; the angle of the light changes. This is separate to anything the lens does. If there's too much diffraction, you won't be able to tell two different sources of light apart. The amount of diffraction depends on the wavelength of the light and the size of the aperture. Bigger apertures and shorter wavelengths diffract less. This "diffraction limit" has a formula accordingly.
So for the question, we make some basic assumptions: take the wavelength of red light as it's the longest wavelength for visible light, and assume he needs to be able to tell apart two light sources 2 metres apart at a distance of 15 miles to distinguish individual riders. We figure out the angle between two points 15 miles away and 2 metres apart and now we know the angular resolution necessary. We know that the diffraction limit of Legolas' eyes has to be at least as small as that resolution. We also know our wavelength, so we can stick those into the formula and find out the minimum aperture (ie, the minimum diameter of Legolas' pupils to make out the riders at that distance)
If you get 50m above the ground and have nothing in the way, you can see 5 leagues away as well. Good luck counting individual people from that distance though. The anime eyes are a necessity
I'd also add that CK3 is a step above most Paradox games in terms of beginner-friendliness. Everything has a tooltip defining what it does, and most of the game-specific words in that tooltip have tooltips of their own. It's not like the older games and their "lol keep the wiki open and good fucking luck" approach to explaining themselves
He's hitting countries like this the hardest too due to his ChatGPT-special formula for calculating tariffs. America has big trade deficits with poorer countries because they are too poor to buy much American stuff, and now he's punishing them for it
Coordinate with China on this shit. The EU and China may have their differences, but they have a common goal here and together they substantially outweigh the US
It's super interesting that they're not social animals either. So much of our brainpower goes towards complex social bonds and effective cooperation, whereas octopuses generally just do not care about that stuff
Since the kW part can cancel out, the resulting kWh/kWp value is basically measured in hours. There are 8,766 hours in a year and half of those are at night, so these numbers would make sense if you think of them as "this is how many hours of peak production equivalent you will actually get each year". You're in the Sahara, you get the equivalent of 2,400 hours of peak production. You're in Finland, you get the equivalent of 1,000 hours. If it actually magically ran at the peak production value all year 24/7, you get 8,766.
Yeah but did he do it with a typewriter? Didn't think so
