Hi
I'm having trouble with coming up with a minimal solution to this problem: create a 8 bit adder/sub using only one 4 bit ripple carry adder and muxes. This is what I'm thinking but I don't know how to make it any bit simpler:
We can calculate the sum of first 4 bits using the ripple carry...

To do this problem, I know that we first have to find motional emf of the loop at time t =0.032 s? I also know that emf= BxvL where v is the velocity where L= velocity*time
But when I try to plug in numbers I'm getting a wrong answer.
emf= 1.2*.4*(.4*.032) = 0.006144 Volts

Homework Statement
An infinite line of charge with linear density λ = 8.8 μC/m is positioned along the axis of a thick insulating shell of inner radius a = 2.9 cm and outer radius b = 4.1 cm. The insulating shell is uniformly charged with a volume density of ρ = -659 μC/m3.
What is Ex(R), the...
oh got it! Volume charge density*Area of the shell = Linear charge density which is
-659*pi*(.041^2-.029^2)=-1.74e-6 C/m
Now, how do I find E(y) at P? Do I just use E = q/(epsilon nought * Area of the Gaussian cylinder at P) or do I use the linear charge density in the formula?
yeah sry for those typos.
anyway, we find the volume of the shell by using formula:
=(Area of outer base-Area of inner base) * Length
=pi*(.041^2-.029^2) *Length
But i do not know the length of the cylinder, that's the main problem I am facing.

so if there are 32 bits, we have 8 decimal digits if we code the integers in BCD(4bits/integer). That means, 10^8 integers(0 to 10^8-1) can be represented in BCD with 32 bits. Is this correct?
