Homework Statement
From Hayt "Engineering Circuit Analysis". I'm just wondering how the imaginary "j" multipliers appeared.

Find the general solution for the current I(z,t) associated with the voltage V(z,t).Do this by substituting [1] into [2] and [3], integrate with respect to time, and then take the derivative with respect to z.

V(z,t)= f+(t-z/vp) + f-(t+z/vp) [1]...
I'm having some trouble with this one
A water sample contains the following ions (all in mg/L except HCO3-)
K+=70, Sr+2=20, Ca+2=180, Mg+2=80, HCO3-=230 mg/L as CaCO3-2, SO4-2=164, NO3-=37, Cl-=400, CO3-2=35, and B=?? has a valence number of 2 but the sign is unknown.

Good point,I forgot to mention that the system is isolated,horizontal and on a frictionless surface.And now I realize that this question relates to more generally to Conservation of Energy rather than to the work-kinetic energy theorem.
OK,with that in mind,say that the object compresses the...
If I apply the Work-Kinetic Energy theorem to a situation in which an object is lifted or lowered then I can form the equation K(f)-K(i)=W(net)=W(applied)+W(gravity)
This equation shows that if K(f)=K(i) then the above equation reduces to:
W(applied)= -W(gravity)
Now in the situation in...
