In cylindrical coordinates, let p = 0 for p < 1 mm, p₂ = 2 sin(2000p) nC/m³ for 1mm < p < 1.5 mm, and p = 0 for p > 1.5 mm. Find D everywhere: ly

Two coaxial conducting cylinders of radius 5 cm and 9 cm have a length of 4.56m. The region between the cylinders contains a layer of dielectric from p = 2 to p = 6 with ER = 13. Find the capacitance in pF. Round your answer to 2 decimal places. Add your answer

I am trying to measure curl of del cross product A where A = -(cos(x) sin(y) + sin(x)cos(y)  ⛛XA   = -(cos(x)sin(y))+(sin(x)cos(y)) Thank you for your time and help!

For the circuit shown in Figure:a. Determine the reluctance values and show themagnetic circuit, assuming that μ = 3,000μ0.b. Determine the inductance of the device.c. The inductance of the device can be modified bycutting an air gap in the magnetic structure. If a gapof 0.1 mm is cut in the arm of length l3, what is thenew value of inductance?d. As the gap is increased in size (length), what is thelimiting value of inductance? Neglect leakage fluxand fringing effects.
