Archived Derive the general solution for current in a lossless transmission line
Homework Statement 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. Homework Equations V(z,t)= f+(t-z/vp) + f-(t+z/vp) [1]...- biker.josh07

Water Chemistry Cation Determination
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. TDS(Total...- biker.josh07

Work-Kinetic Energy Theorem applied to a Spring Force
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...- biker.josh07

Work-Kinetic Energy Theorem applied to a Spring Force
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...- biker.josh07
