bump for mechanics

Are you trying to find the equation for the movement or the velocity? I think it's not possible in this case

The frictional force will never be greater than the force applied to the object that it is opposing, it increases as the opposing force does until it caps out at F(max). The way of calculating it is V(object)*mu(static or kinetic). As you know, mu only varies with object material.

sample questions:
____thousand = 8,000 ones

700 = ___ tens

I don't get it

fuck off

>does not rotate
>has spin
If that's the case then physicists must have some crazy definition of spin.

It has it's spin in an "abstract" coordinate system. Just next dims.

How do you cope with living in the kernel of a rank 1 map?

In my domain it's image looks so blue.

are you talking about stem tillering rate?
because theoretically a long lived perennial wit strong tillering tendencies could cover an entire lawn within a few years from one single seedling, 30 days seems a bit excessive
please clarify further

>>7628786

Upper right. The point is to add all the boxes on the same side and then substract all the right boxes from the left boxes of same colour.

>>7642345
2 black squares on the left.
It's pretty self explanatory.

Use Basic Mathematics by Lang, it's what I'm using and it's good.

>>7642283
A book? I would prefer to do it on the internet if possible?

>>7642283
Actually I Googled that book and I think it's too advanced for me.

I just need something really basic.

>>7642191
You don't know that.

Now fuck off.

>p-progress is infinite humanity fuck yeah guys xD

>What is the Haber process

Humanity reduces local entropy on a daily basis.

>>7642110
it is trivial as the book says

>>7642115
Actually is says elementary..
Can you show me the steps or are you just here to be funny?

>>7642110
Does anyone has any idea?

>>7642029
Statistics or something, I don't know

youre going to reinvent the wheel? pokeracademy software, which has done all the maths for you, is what you want.

Study probability and learn to count cards. Black jack is the game with highest win ratio for the player (even though the house allways wins.)

Infinitesimal * infinitesimal = 0. It's part of the so-called "sloppy calculus" used by physicists/engineers. (There is a rigorous way to define calculus using infinitesimals but it's normally done with limits and physicists don't use it anyway.)

dm and dv represent infinitessimal quantities of the mass and the velocity. The value of their product is so small that we can consider it zero.

>>7642033

Why is dm and dv infinitesimal?

Arent they variables - surely they could be anything? or am i being dumb

It's sad that /his/ neglects the other humanities so much...

Anyway, yeah, you can't seem to get around the induction principle
(Just like you e.g. can't prove that it's not the case that 10 minutes ago aliens came to us and implemented memories in our brains that do not involve them + that make most people disregard the possibility that aliens just did this manipulation.)

So you adopt the scientific method as a <method> that has been proven useful.

Also, Feyerabend reminds me of Feynman...
"Fey" \implies student fucker

>>7642070
Some anons seemed to be making the point that due to these problems, science should not be taken more seriously than other branches of thought.
e.g. saying 'science proves x=y' is not necessarily any better than saying 'Marx has shown y=z'
Apparently the scientific method is not impartial or neutral and is in fact an ideological tool of the powerful to enforce their own interests.
I just went there to talk about the Romans, but I got interested in a lot of the philosophy threads, and how people were not genuflecting to empirical research and being very skeptical of any claims of sciences superiority to other disciplines.

Surely fucking students is the only reason anyone goes into academia? Hawking knew he wouldn't get pussy on the street

>is itself an ideology
a completely uncontroversial statement to anyone with even a cursory knowledge of philosophy of science

>not necessarily to be trusted
we knew there were problems with the scientific method long before Feyerabend was even born

huh?

>>7641706
yes

the answer is aliens

>>7641700
THE THING WITH MATH AND /SCI/ENCE IS THAT YOU CAN CALCULATE IT
FIND THE DENSITY OF AIR AND THEN ADD THE AMOUNT OF THAT AIR INTO THAT 5KM SHAFT AND SEE HOW MUCH WEIGHT IS APPLIED TO THE STYROFOAM BALL IN THAT HOLE

>>7641700
pressure is caused by the huge amount of material above the object being held in place by gravity. It's crushed by the WEIGHT of the atmosphere/ocean, so in that sense it is caused by gravity. But without any material if you sunk that same styrofoam ball in a vacuum tube, nothing would happen as long as the material in the tube itself could withstand all the pressure the ocean is exerting.
