Hi,
I am currently majoring in computer engineering and I don't know if going in the right path. I am enjoying my computer engineering courses but I also want to do a lot of the stuff that is offered in software engineering. My questions are:
1) How much of a difference (programming wise)...
Homework Statement
test if (1+4^n)/(1+3^n) is convergent or divergent.
Homework Equations
The Attempt at a Solution
using the ratio test. i got it equal to 5/4 which is > 1, so it diverges. can someone check this? what other methods are available?
Homework Statement
integral of cos(x)/(x^4)
Homework Equations
The Attempt at a Solution
tried using integration by parts but lead to tons of work!. is there a simpler way?
Homework Statement
Find the equivalent capacitance of the picture in the attachment file
Homework Equations
The Attempt at a Solution
The circuit is neither in parallel or series. I tried breaking it up into series and parallel but it seem too easy to be correct. Any tips on solving this?
im not an expert so I am not 100% sure but...
a=F/m
the forces acting on each other is equal but the masses are different.
the proton, which has a bigger mass, will have a slower acceleration
the electron, which has a smaller mass, will have a faster acceleration.
in my conclusion, i think...
Homework Statement
1)Coulomb's law states that the electric force becomes weaker with increasing distance. Suppose that instead the electric force between two charged particles were independent of distance. In this case, would a charged comb still cause a neutral insulator to become polarized...
yes, it should look like that. thanks.
i don't know how to find the forces.
would it be like this? assuming the Q's are: Q1(top left), Q2(top right), -Q3(bottom left), -Q4(bottom right)
FQ1=[k(Q1Q2)/x2]+[k(Q1-Q3)/d2]+[k(Q1-Q4)/(x2+d2)]?
and i do this for Q2, -Q3, -Q4?
