    Finding magnetic field in wire with non-uniform current density

    I ended up getting it. You solved for C first by defining dA as 2*pi*r*dr... that was the part I couldn't get.

    Finding magnetic field in wire with non-uniform current density

    Homework Statement Find an expression for the magnetic field inside a wire carrying a current density J = Cr2 where C is a constant to be determined in the problem. The total current in the wire is I and the radius of the wire is R. Your answer should be a function of r, R and I, but should not...

    How long does it take for the cone to drain completely?

    Technically I know that A= .5(m2)∏...but I can't write that like I can dA/dt I can write V in terms of m -> V=∏m3,and get an equation for dV/dm...does this help?

    How long does it take for the cone to drain completely?

    Homework Statement A circular cone (height H = 2m, radius of the top R = 1m) with a vertical axis and the vertex pointing down is fi lled with water. At t = 0 a small circular hole is opened at the vertex. By Torricelli's law, the rate of change of the volume V = V (t) of water in the...

    Moment of interia about axis d

    I thought you used d and L-d because that was the length over which you were integrating. It's always just over the total length?
