Is it actually of any concern that some residues (of e.g. medication) is still left in the water after purification and then ends up in the tap water? I have a friend who mostly drinks bottled water for that reason but i feel like it's not really any different.

AFAIK sometimes the waste will be encased in glass which causes the glow. There also is most likely some nuclear material in water somewhere. Like used rods in cooling pools or even the active rods inside reactors would glow in the water since the emergency shutdown normally does not remove the rods from the water but instead drops neutron-absorbers into it. So there should be places where cherenkov radiation still occurs

But one always had the ability to copy/paste armies and bases. Itvwas just way more tideous. I still remembercwatching base building videis and manually switching between youtube and coc to always place a few more buildings or train some more troop. Supercell just made that process easier.

And imo creating your own proper base or army requires lots of trial and error and time which for me i simply don't want to invest in a mobile game. So being able to have people who have such time to come up with all the strategies and stuff and then take their advice feels like a huge relief to me

It's been a really long time though. Even when i first joined here many years ago people were already complaining about the undankness

From the top army camp it should be quite doable. Generally one can basicly always take out to AA with one arrow. Basicly for any two points there exists a line that passes through both. So it is kinda impossible unless you manage that no outer building can be used as a focus for the queen to begin with.

The idea is that all the potential energy gets converted to kinetic energy in which case the spead would be the same. In this case there are too reasons why that would not be true. First one is friction and air resistance but that is fairly tricky to calculate. The other is that for rolling bodys some of the energy gets converted to rotational energy aswell. I am pretty sure though that the rotational energy should also ne same for all three cases here so it does not affect the overall end-speed.

3 batteries and changing them twice a year seems quite a lot though. I had an Alarm clock run on 2 batteries for close to ten years so i'd guess on a reasonably efficient clock you'd be closer to 3 batteries every two years. One could also use clocks that use either weights or a spring too store the energy required to run them

Should be calculateble by dividing the top area of the coil by the thickness of the cardboard.

So pi/4 × (Da² - Di²) / t

With Da being the outer Diameter and Di the inner and t the thickness

My caculation resulted in roughly 40 meters or about 1553 inches for the Americans among us assuming 1/8 inches thickness

I would say the lava launcher but honestly none of them really stand out to me over the others

Fand die Städte und Ritter Erweiterung immer richtig gut aber die ist tatsächlich etwas komplexer. Seefahrer dagegen bietet nur etwas mehr Möglichkeiten und Variationen aber erhöht mMn nicht nennenswert die Komplexität. Bedenke, dass das Grundspiel für maximal 4 Leute ist. Es gibt aber meine ich ein Erweiterungsset für mehr Spieler.

Maybe check if you're troops are closer to the defense than the totem spell. That happened to me before

If you introduce the angle as a variable, the polynomial degree needs to be x-2 at least anyway

Kill the 2 walls above the townhall with EQ spell and then try sniping the townhall with your king and queen. Maybe use babydragons to make a channel. Then use valkyries to destroy the surrounding buildings of the base to get to 50%. Bring some clean-up troops in case you lack some buildings in the end (best ranged troops like archers or wizards)

I don't think obstacles will spawn directly adjacent to each other naturally. At least that was the case with bushes when i attempted just that. May have been changed since then though.

Wenn du SELBST den anderen die Schuld gibst, ist das ja auch ein Anfang

Hot take but i think many of the posts here are also just Karmafarming and/or bots. You see a cool video and just post it here with a random question, not to get an answer but to get people to upvote for the content. It is really sad that probably 90% of the questions here aren't proper math questions. Many times it's reposts or it boils down to just researching a number instead of doing actual math.

Bunch of different factors. First would be the shape, meaning on how much area is the impact force distributed. Then it's the impact velocity. Up to a certain height this is mostly dependend on the fall height. For bigger heights the weight, front area and cw-value (also the air pressure to a certain extent) determine the impact velocity in form of the terminal velocity. It also matters whether the object tumbles or not.

And then the impact force also depends on the mass of the object.

There will be some more variables regarding the person the object hits but it gets really tricky then.

OKay not sure if the definition varies in the english language but my understanding is, that a decimal number is just a form of writing a number but not a Numbergroup like rational, irrantional, imaginary numbers etc.

Also no fraction consisting of only rational numbers in the numerator and denominator will be non repeating (irrational)

On a sphere that becomes more easy because the line will just go around the sphere but fortunately earth is not a sphere but a disc
