that guy is a fucking nerd.. it requires more skill to be a professional athlete than a scientist.. theres plenty of retards that are scientists

Yeah, but it's much easier to become a famous athlete than a famous scientist. Note the difference between fame and success.

How many scientists can the average person name if asked? How many sportspeople?

The steepest railroad track that allows trains to move using their own
locomotion and the friction between their wheels and the track is located
in France. The track makes an angle of 5.2° with the horizontal.
Suppose the rails become greasy and the train slides down the track
even though the wheels are locked and held in place with blocks. If the
train slides down the tracks with a constant velocity, what is the coefficient
of kinetic friction between the wheels and track?
Oh and by the way the answer is .089

thanks though i doubt i could get these on my own

close, remember, a full circle is 2pi not pi.
so throw a 2 on your angles and youre there

Prove that .99999...=1 using series. Just did that myself.

here is a classic:

an hiv test has a false positive 1/10000.
1 / 100 is a false negative.

you take two, and the first is positive and the second is negative. what is the chance you have HIV?

dude you guys are not even asking homework questions you are just asking brain benders or shit you know the answer to...

MINE are actual homework questions due in a few days... that i don't already know the answers to... so...

>> No.2133638

>>2133627
So homework is something you don't know the answer to? The .999999=1 was relevant to some homework I did already today. I'm probably going to go through my Number Theory shit so if I find something there I can't get i'll post it sure.
