anonymous · Answer

Distance from brain to toe in meters is..?

anonymous · Answer

well, it takes a finite time for your brain to register that pain. So, given that this signal travels along the nerves at 100m/s & given that the distance between you toe & your brain
is about 6 feet, calculate the time it takes that info to reach the brain.

anonymous · Answer

$$vt=d$$
$$v=100 m/s$$

estimate $d$

shubhamsrg · Answer

ohh..get it now..hmmn

lgbasallote · Answer

i see...so we make the distance into 6 feet?

anonymous · Answer

Your height, yes

lgbasallote · Answer

that was easier than i thought o.O lol

anonymous · Answer

if we were being really precise d = length of human + length of foot ftw

anonymous · Answer

yeah, approximately. I think they just want you to get a feel for the time, qualitatively.

anonymous · Answer

java, how long is a string?

anonymous · Answer

thats easy, its limitless :)

lol

anonymous · Answer

another reference :D http://www.youtube.com/watch?v=JLIwuWNOWBk

lgbasallote · Answer

suppose im 1.68 meters tall do i do it $$time = \frac{1.68}{100} = 0.0168s$$

anonymous · Answer

where are you going with this? is the the origin of your alias ?

anonymous · Answer

nope, java. just a relevant reference.

anonymous · Answer

click the url and watch that

anonymous · Answer

yes, lgba.

anonymous · Answer

v = d / t
t = d /v

lgbasallote · Answer

great!!!

anonymous · Answer

il watch it later cheers

anonymous · Answer

now do you know what 17 milliseconds feels like?

anonymous · Answer

but we can still feel that lag? do u know what i mean?
