You have mass flow rate and velocity, but the area this is spread over will say a lot - $$\dot{m} v = F = 1 {{kg} \over {s}} \cdot 1,000 {{km} \over {s}} \cdot 1,000 {{m}\over{km}}= 1 \times 10^{6...
Tornados and the thunderstorms that often spawn them are driven by rising columns of air. Such "thermals" are stronger and more likely in open terrain, like is prevalent in Tornado Alley. Let the...
Whatever means you use, it would make sense to have two measurements: Time To Destination (TTD) relative to yourself, and TTD relative to the destination. E.g one year for you, two years for the pe...
I'd recommend a Kalman filter to increase measurement accuracy to the overlap of multiple system errors so that you get the best result. For inputs, may I recommend - a calculation of doppler s...
I think it's unlikely. Colloquially a year is 365 days. But if you actually watch Earth complete an orbit in space, it will not be at the same rotation around its axis at the end as when it starte...
No, the scheme described doesn't make sense, regardless if it is digital or analog. Anybody can intercept the public key and decrypt so the scheme doesn't protect against eavesdroppers. The entiti...
I've noticed that some questions have a mismatch between the number of answers showing in the question list page, and the number of answers showing on the specific question page. For example, the R...
Golf morphs into a multiple players action sport Nothing could be more boring than watching one person hit a small ball, then trudging after it while wearing trés chic golf pants and visored caps....
Previous Concepts I did a quick literature review for this on google scholar, and unfortunately it seems like there isn't much research on the topic. I did however find this short article, which h...
I think a reasonable assumption is that you don't want to accumulate entropy from the Dyson sphere. That is, the entropy you get from the star must not be lower than the entropy you send to outer s...
Both the other answers (at this time) suggests making the orbit eccentric. The variable distance from the sun makes the planet hot or cold. This is correct. But there is one important aspect of ...
As L.Dutch said, lightning is super energetic and any plant probably wouldn't survive it's strike. What I can imagine is the forest benefiting from some of its trees taking the hit for the team and...
Depends on the orbit I'm drawing on my answer to a different question here. Let's start with an overview of why there are seasons. I really like this description: We have seasons because the e...
Yes, it can. We can determine the distance to the source if we have an idea of what's causing that shift in velocity. Let's say that we have a source moving at a speed $v$ away from us. If it emit...
It would depend on the eccentricity of the orbit and the size of the orbit. So there are a number of orbital possibilities to consider. The problem even more complex because of a number of other va...
Not gonna lie here, that looks way more like an disadvantage than an advantage. The main problem here is that this seems like an unnecessary redundancy. Yes, morays have 2 sets of Jaws, but the se...
Your star is not going to work, so the planet won't either. Mass of star: 1.04 M☉ Radius of star: 0.69 R☉ Surface temperature of star: 4,620° K Luminosity of star: 0.2 L☉ ...
Leaving aside the durability issue, you should probably be looking at electronic paper. They work by moving colored particles back and forth to create the image. The term you're looking for is call...
No. The way we define latitude and longitude is based on the planet's axis of rotation. You can certainly (AFAIK) have a planet with a 90° axial inclination, or (probably) a planet that is identica...
For an in-situ born planet, it can happen, though it is hard to have the exact chain of events. Basically you need to have a series of gravitational slingshots with a larger body that put your pla...
I think that this topic is one that's likely to generate a lot of misconceptions when people answer it, since it's a complicated topic and analogies/explanations that are given by pop science are o...
Let me see if I got this right. You want to conjure an object, have it contain enough mass and gravity to collapse on itself without dissipating, motivate it to move at FTL speed, drag your vesse...
Interpretation: ET's blood equivalent is primarily composed of caramel, with some additional components, but without hemoglobin. The flesh tastes terrible, without rendering the caramel blood ined...
I'd imagine that they'd build double skinned shield walls to deflect the noise from waterfalls. The most expensive parts of the city would also be the quietest, while the slums would be where the s...
100% YES It s called an updraft tower. You can actually even do that on earth in the Deserts (solar updraft towers). https://en.wikipedia.org/wiki/Solar_updraft_tower On Venus you wouldn't even...
