If we create a high vacuum in a bottle and immerse it in water and then open the cork.which way will it go ?
will the bottle move backward (towards the nozzle) or forward?
i have a doubt which popped up when i was looking up rc copters.
which is better multiple rotors or a single rotor?
which provides better thrust to power ratio?
which is more efficient?
assuming ideal conditions?
so you mean total angular momentum of small disk about axis 1 is the sum of angular momentum of the disk about axis 2(here, assuming it doesn't rotate about axis 1) and the angular momentum of the small disk about axis1 (here, assuming it doesn't rotate about axis 2)?
Homework Statement
if a disk is rotating on another stationary disk and someone standing on the stationary disk stops it what will the final angular velocity of both the disks be?
the catch is that both the disks are not co axial. assume ω angular velocity, M mass of big disk.m mass of small...

how do we get the n th term of a sequence if it is given in form of
##x_{ n+1 }=f({ x }_{ n })##
and the p th term is given

I figured we may get it if we get it in the form of
##x_{ n+1 }-{ x }_{ n }## but how?can we even get it?if yes,under...
Recently me and my friends started undergraduate courses following our interests(mostly engineering, science and maths).
can anyone suggest some great books for reference and to use as guides for the respective courses?

well the ratio of successive terms is
##\frac { 10 }{ x+1 } ##
and for x>9 the ratio is <1.so that means, as x→∞ the ratio tends to 0.so if we continue multiplying the equation with ##\frac { 10 }{ x+1 } ## ultimately it tends to zero so the limit is zero!
is my logic correct?
Homework Statement
find limit
##\lim _{ x\rightarrow \infty }{ \frac { { 10 }^{ x } }{ x! } } ##

l'hopitals rule
The Attempt at a Solution
on substitution we get
##\frac { \infty }{ \infty } ##
on using l'hopitals rule,what is the result of differentiation of x!?

how does a slow spinning gyroscope behave?
does it behave as a normal fast spinning gyroscope would?
if the mass of the gyro is large so that the angular momentum equals a fast spinning gyro does its precession equal a fast moving one?
can anybody explain?please.
