From this figure we could see the axis of rotation of wheel is y axis and it's translational motion is along x axis
How would I describe it's horizontal motion in terms of rotational motion
The wheel is spinning and also moving horizontally along x axis
w being the angular frequency
hello everyone
we demonstrate the linearity in a function by a superposition principle..as in f(x)=y
f(x1+x2)=f(x1)+f(x2)
but that' the case when we have a single variable as x and if we have two variables then we modify the concept of linearity to multilinearity where f(x,y)=z
can never be...
i mean we mention differential equation to be linear..as linear differential equation..
and for the example if we take this LDE dy/dt+(x^2)*y=0
it is LDE as for the dependent variable and its deriavtive is in first degree and are not multipled together..please let me know i am wrong...
hello..
i am understanding a little bit now but if i have to say linearity of functions involving more than two variables then i can't always refer to superposition principle or is there any superposition involving more than two variables..!!
and if i have to consider the linearity among...
need help understanding "Superposition Principle"..!!
hello everyone..
if we have a function y=f(x) then in-order to prove linearity we try to justify according to superposition principle as :
let x1 and x2 be two inputs then f(x1+x2)=f(x1)+f(x2)
please correct me if i am wrong upto here...
hello
amm..so i guess it all depends on perspective and the matter in which the label is associated with the company..and we could say it anything and it all depends on the marketing strategy...
correct me if i am wrong thanks..!!
how do we define and categorize technology..??
there are presently different aspects in which the technologies are discussed
if i say semiconductor technology then should it mean..
1) technology that processes semiconductor materials to get high performance electronic devices..??
2)...
i totally consider the fact that electric field lines are merely (rather continuous) the tangential representations of force acting on unit charge at that point which is definitely a vector and flux measures the flow of electric field lines through a particular defined surface δs and that is...
what is flux...?? is it a scalar or a vector and difference bet flux and flux density
i have read the articles where the flux (either in case of electric flux or magnetic )is described as the no of lines passing through a surface area ( open in case of magnetic characterized by boundary and...
difference between particular integral and particular solution..??
particular integral and particular solution are used to find the solution of differential equation..but sometimes they are used interchangeably but what's the difference between two..??
please state examples..!!
no what i actually wanted to refer is that double layer helps or actually shields the electrodes allowing the discharge only through connecting wires..!!
although it doesn't allows passage of electrons but still because of ions it is still conductive..!!
so on the overall this dl thing helps...
ok so can i say that any n by 1 or 1 by n matrix has rank of 1 ..!!
but what if the independent rows or row vectors and columns or column vectors have value more than 1 like i have an example as:-
x1=(1,3,4,2)
x2=(3,-5,2,2)
x3=(2,-1,3,2)
so here i have three vetors x1,x2,x3 out of which two are...
i agree with fact that something being stated as conductor is one that responds to electric field with its own charges..as ions in case of electrolyte and in case of solids in which tere are no free ions the electrons serve as charges for conduction...!!
but i am here concerned about the point...
ok..but here you have mentioned about column rank...but i am asking here is a different thing..i am asking about how to find the rank of column matrix or column vector i should say..!!
that's because electrolyte is a good conductor..and if the attached load is of mega ohms or
an other higher value..won't the electrolyte would provide the shorter path between the terminals...!!
won't the electrons prefer the shorter path instead of going a way long from one electrode to...
hi there
infact i am quite asking about how to calculate the rank of a column or row matrix..??
and here i have just taken the example of row matrix..but i would also like to know about determining rank of a column matrix..!!
ok so what it is that's preventing the movement of electrons in electrolyte but yet allows the movement of ions..??
why we observe this kind of behavior..!!
hi there
ok so electrons can not go though but ions can..is this all happening due to the formation of DL(double layer) that acts as an insulator between electrode and electrolyte..!!
http://en.wikipedia.org/wiki/Helmholtz_double_layer
hey guys
i have put this question to clarify some points on battery anode cathode reactions...let me describe this..if we consider the cell to be two electrodes with in between electrolyte ..
at anode one has the situation:
metal=metal ion+electron released
i.e oxidation takes place..!!
so...
how to calculate rank of 2 by 1 matrix..??
hey guys so i am well familiar with finding out rank of square matrices but if matrix is just a row or column vector then how to determine its rank..considering the example below:
a=[x1
x2
x3]
where is column matrix while x1,x2,x3 are...
ok so nuclear reactions don't produce something from nothing but they however converting the electron positron pairs from neutrons that is something that resides in nucleus and the relation e=mc^2 is just a conversion factor to judge the energy of a body...!! can i say this by summing all..??
so can we say this conversion of E=mc^2 doesn't happen at all
because it what we perceive from different reference frames due to account of special relativity
and we can't say that
actually a some lump let say of m mass is vanishing(or more precisely should i say converting to energy)...
can wave particle duality be viewed at macroscopic scale...??
ok so far we have discussed the wave particle duality in case of electrons of-course at microscopic level through the
1) interference phenomenon showing its wave behavior
2)photoelectric effect discussing its particle...
