Probably meteorites.

so something like 20 to 40 km/s?

>>9105723
Probably that manhole cover during that underground nuke test. Some of the more generous estimates put it at escape velocity.

>>9105537
Sounds like perpetual motion. It must have been explained wrong. This usually happens when the exlpainer him/herself doesn't understand the mechanics.

wind turbine still works even if its attached to a car..

how do you think a sailboat works

>dead downwind faster than the wind works
and dead upwind faster than the wind works too

The first. Erosion by water is caused by a combination of the amount of water and the velocity of it. With the quantities matched, the added velocity is going to provide extra erosion.

It's also worth noting that repeated freeze-thaw cycles can crack concrete and significantly speed up erosion, but in your case it's just going to be a single cycle and probably won't have much effect.

That's a pretty intuitive answer that makes sense to me, thanks anon.

Well that got resolved

Now what do we do next?

Culture is hereditary but not genetic.

Nobody is saying that gangsta culture is a good thing.

I don't understand the question, also the pic choice is retarded.

If it replicate can be trusted. Just like studies about Einstein Theory of Relativity.
Psychology by other hand rarely replicate, so cannot be trusted.

Replication = redo the experiment with same results by different research groups.

>>9105294
make sure it comes form a reputable journal and I guess make sure it's a couple years old so there's been some time for other papers to reanalyze the claims, and check for said papers either corroborating or disagreeing with the original paper

>>9105313
Couldn't someone argue that the replicating group matched their numbers to artificially confirm the results? I know this is going into conspiracy theory, but I'd like to cover my bases.

>>9105320
I think I'm gonna have to start documenting my go-to studies and their authors and keep them handy on my phone. "I read in a study from a university" isn't cutting it anymore.

>>9105191
If the points labelled +2V and +1V weren't blocked with diodes, the current would flow from +3V to them. Since they are blocked by ideal diodes, there is no current there. There is a +1V and +2V voltage jump from left to right over the diodes, respectively.

>>9105191
Just found a guy on youtube on some obscure page doing this exact problem. He says if all of the diodes conducted, the point to the right of them would have indicisive voltage, so only one can conduct.

Why couldn't it be the sum of all voltages?

Am I right to think that if that point was 6V by summing the voltages, then the diodes wouldn't be foward biased, so they'd be off?

>>9105200
Am I misinterpreting your explanation... Wouldnt that mean that the resulting voltage on the right side would be +6V?

Having bad grammar in a math problem is kind of a problem. I'm not even sure what you're trying to ask.

You have to stop wording your homework questions like this. We can smell it from a mile away that you're just trying to get a quick answer out of his. Maybe if ask real nicely we will help you, brainlet.

>>9105169
there is something missing - if you have say a trapeze and know the length of the parallel sides and the height, then you can still translate one of the parallel sides which doesn't change the height, but the lengths of the diagonals (the "x").

Do you even Pythagoras?

>>9105169
Your handwriting is a little unclear. What are the numbers?

Many life sciences are actually pretty interesting, but the educations themselves are relaxed and their students ends up brainlets.

When you get to the acedemic level it's much different.
A BS in math is the best degree you can have to go into post graduate studies in theoretical life sciences. Check out pick related, ecology is naturally comfy for maths.

The chemical that saved /sci/

they rarely do, it's called electron capture
the probability is small though the reason being the atomic state is more stable than the dissociated state

Simple, because like all of the other rich guys out there into this shit, he is a business man. He doesn't understand these topics. Rich people surround themselves with smart people to get shit done for them (not saying he isn't intellegient). Since they possess leadership and people skills, they can form these big companies and accomplish great things.

Eventually, these dumbasses start to think they underdtand every aspect of science from economics to solar powered dildos and go preaching as if they are some sort of saint. No, A.I. won't program itself EVER to be malicious or take over the world. Any slapdick who took a class in computer science/programming knows this. No computer has the emotional know how (and will never) to try and make itself sentient and overthrow it's creator. That's movie-tier bullshit.
