    8 bit adder/sub with 4 bit ripple adder and muxes only

    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...

    What is the motional emf of the loop at time t = 0.032 s?

    EDiT: 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

    What is the motional emf of the loop at time t = 0.032 s?

    Homework Statement A conducting loop is made in the form of two squares of sides s1 = 3.8cm and s2 = 6 cm as shown. At time t = 0, the loop enters a region of length L = 18.6 cm that contains a uniform magnetic field B = 1.2 T, directed in the positive z-direction. The loop continues through...

    Is B={0,1,R,F,X} a Boolean Algebra?

    AND | 0 1 R F X ---- |--------- ---0 | 0 0 0 0 0 ---1 | 0 1 R F X ---R | 0 R R X X ---F | 0 F X F X ---X | 0 X X X X NOT x |~x ------ 0 |1 1 |0 R |F F |R X |X so obviously R' =F and vice versa

    Line Charge and Charged Cylindrical Shell

    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...

    Line Charge+ insulating Cylindrical Shell

    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?

    Line Charge+ insulating Cylindrical Shell

    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.

    Exploring 8-bit BCD and Integers: How Many Can be Represented?

    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?
